EXECUTIVE SUMMARY
Objectives
The aims of the work reported here were:
• To assess the BS EN ISO 8662-10 (pneumatic tools) and the BS EN 60745-2-8 (electric
tools) emission test for usability and repeatability
• To assess reproducibility by comparing our results with manufacturers' declared
vibration emission values (and verifying in accordance with BS EN 12096)
• To compare vibration emission values with vibration magnitudes measured under real
operating conditions
• To assess vibration emission data as an indicator of vibration hazard.
Main Findings
1. Manufacturer’s declared emission values as measured according to BS EN ISO 866210:1998 and BS EN 50144-2-8:1996 (predecessor to BS EN 60745-2-8) were verified
according to the criteria in BS EN 12096:1997 in 4 out of 7 cases; 2 out of 7 cases were not
verifiable. The remaining case was partially verified dependent on the test material and
direction of operation.
2. The current standard test methods do not specify one particular test material or a range of
test materials. It is therefore unclear to what type of material the manufacturer’s declared
emissions relate. This research has shown that for one tool cutting three different types of
material, the total vibration value can vary by up to 30ms-2.
3. Based on the data in this study, single axis a emission values may be lower than the total
triaxial a emission values by up to 62.2%.
4. There is great potential for vibration levels to vary between materials, operators, tools and a
combination of all three factors. Operator skill and experience also play a role.
5. The amount of material to cut off for the purpose of a repeatable and reproducible
laboratory test is undetermined due to the amount of variation possible. Varying the width
of material to cut off introduces another variable into an already complex situation. The
specifications in EN 60745-2-8/prAA will help.
6. For electric tools, the triaxial transducer locations on top of the tool in EN 60745-2-8/prAA
will yield a higher vibration value than the current standard test (single axis underneath the
tool). For pneumatic tools, BS EN ISO 8662-10 (transducers located underneath the tool)
triaxial measurement will yield a higher vibration value than the current single axis
requirement.
7. Transducer location influences vibration magnitudes. For electric tools, EN 60745-28/prAA overestimates the mean in-use values (transducers on top). For pneumatic tools,
BS EN ISO 8662-10 underestimates the mean in-use values (transducers underneath). End
users of the tools are at risk of not being in possession of data representative of vibration
hazard.
8. It was not possible to investigate in-use values in terms of emission upper quartile data due
to a lack of field sites.
9. The current test methods do not take the efficiency of the tool into account. Vibration data
should not be used in isolation to identify the best tool for a particular application.
v
Consideration must also be given to the rate of work achieved and suitability for the
application.
10. Tools with plastic handles, whether the main handle or an auxiliary handle, can resonate
which influences measured vibration data. This can be identified by unrealistically high
and/or wide ranging measured vibration data e.g. tool E has a total value range of 22.7ms-2
to 40ms-2.
11. Measuring the vibration level when the cut is as near the test bench as the tool under test
allows will give a worst-case scenario i.e. gives the highest value.
Recommendations
The data in this report show that for any one tool, performing any one task on any one material,
a range of vibration data may be applicable depending on these parameters and the additional
influences of operator skill and experience. There is evidence to suggest that current test codes,
with single axis data, underestimate operator exposure, although this is being addressed to some
extent in the revision to the electrical tools test codes. It may be prudent to investigate similar
circumstances for the pneumatic tools.
Tools with (hollow) plastic handles, be they the main handle or an auxiliary handle, yield
unrealistically high and/or wide ranging vibration emission values due to complex modal
resonances and dependant on transducer location. Previous HSL research has suggested that this
may be the case for a number of tool types and not just those investigated here. Future revisions
of standard test codes – not just for nibblers and shears but hand-held tools in general - should
address the anomalies associated with the design of light plastic handles of novel shape.
Current standard test codes do not specify what type of material to use for cutting. Whilst it has
been shown that the choice of a single material is difficult due to the range of materials a single
tool is able to cut, there is evidence to suggest that thicker materials within a tool’s cutting
capacity give higher vibration values. Specifying a range of materials of different tensile
strengths and thicknesses in the standard test would yield a range of emission values
representative of the tool’s usage.
There is evidence to suggest that hand-held nibblers and shears are no longer commonplace on
the shop floor. This has been demonstrated by the difficulty encountered when trying to find
sites for the field measurement phase of this project. Correspondence with potential field sites
revealed that mechanised processes such as plasma cutting have slowly replaced traditional use
of the tools. Where the tools are still used on the shop floor, the trigger times are short and the
frequency of usage low. Tool usage may still be found on construction sites, trimming cladding
or ducting to size, but the trigger times here are even shorter and the frequency of usage even
lower than on the shop floor.
These tools appear to present low risk unless used extensively and deserve a relatively low
priority.

INTRODUCTION
The Health & Safety Executive (HSE) has an ongoing programme of research with the Health &
Safety Laboratory (HSL) which investigates the relationship between manufacturer’s declared
vibration emission, HSL measured emission and vibration measured during simulated real or
real use for different categories of tool. This report describes the investigation which has been
carried out for nibblers and shears.
1.1
DECLARATION OF VIBRATION EMISSION
The Supply of Machinery (Safety) Regulations require that, among other information, suppliers
of machinery must declare the vibration emission of their tools and machines. The purpose of
declaring such information is to allow purchasers and users of tools and machinery to make
informed choices regarding the vibration emission of a potential purchase.
The method of declaring vibration emission is to apply a standard test to a machine or tool. The
purpose of the standard test is to provide a repeatable and reproducible method of estimating
vibration emission. To achieve this, many standard tests are based on artificial operations. For
this reason, there is concern that the vibration emission data produced from the standard test
may not reflect the vibration produced by the tool when in normal use. For hand-held power
tools, the declared vibration level will generally be derived from a CEN or ISO standard test
code, such as the ISO 8662 series or the BS EN 60745 series of standards. The current versions
of these standards mostly specify the measurement of highest axis vibration. However, a
recently issued B-standard, BS EN ISO 20643:2005 which replaced EN 1033:1995, now
requires that new test codes for vibration emission of machines should both;
• measure the total value of the frequency weighted vibration (derived from the
root-sum-of-squares of the vibration in three axes) and
• be designed to produce emission values which correspond to the upper quartile
of vibration magnitudes resulting from intended uses of the machinery.
This will bring the process of emission declaration in line with the techniques for assessment of
human exposure to hand transmitted vibration as defined in BS EN ISO 5349:2001 and as called
for in the requirements for quantification of exposure in the Control of Vibration at Work
Regulations (2005).
The declaration of vibration emission values is standardised under EN 12096:1997. This
standard defines the following vibration related parameters:
1.
Measured vibration emission value, a, in m/s² represents the measured vibration
emission value of a single machine or the mean value of a reasonably large sample from
a batch of machines.
2.
Uncertainty, K, in m/s² is a value representing the measurement uncertainty of the
measured vibration emission value a, and also, in the case of batches, production
variations of machinery.
3.
Declared vibration emission value, a+K is the measured vibration emission value, a,
and its associated individual deviation value, K. The sum of a and K indicates the limit
below which the vibration value of an individual machine, and/or a specified large
proportion of the vibration values of a batch of machines, are stated to lie when the
machines are new.

OUTLINE OF WORK
The aims of the work reported here were:
• To assess the BS EN ISO 8662-10 (pneumatic tools) and the BS EN 60745-2-8 (electric
tools) emission test for usability and repeatability
• To assess reproducibility by comparing our results with manufacturers' declared
vibration emission values (and verifying in accordance with BS EN 12096)
• To compare vibration emission values with vibration magnitudes measured under real
operating conditions
• To assess vibration emission data as an indicator of vibration hazard
In order to achieve these aims the vibration emission of each tool was simultaneously measured
according to the relevant vibration test code (single axis), the recently re-issued B-standard (tri­
axial) and the proposed revised electrical tool test code. Additional laboratory tests were carried
out with the electric tools investigating the influence of the work piece, distance from the test
bench and direction of cutting on the measured vibration magnitudes.
After laboratory testing the tools were taken into a typical work situation where their vibration
emission under (simulated) real operating conditions was measured.
1.3
TERMINOLOGY FOR EMISSION DATA
The vibration emission measured by HSL for the purposes of this project is referred to as the
‘measured emission’. The vibration emission declared by the manufacturer, and supplied with
the tool, is referred to as the ‘declared emission’.

TOOLS TESTED
Hand-held nibblers and shears are a rare species. Once commonplace in the industrial working
environment, they have slowly been replaced by mechanised processes such as plasma cutters.
The choice of tools to test for this project was governed primarily by manufacturers who still
make and supply hand-held nibblers and shears. Manufacturers of the tools were approached
and asked if they would be interested in taking part in the project by providing tools in return
for a copy of the report.
Seven tools were used in the project, four nibblers (two pneumatic and two electric) and three
shears (one pneumatic and two electric). The nibblers were all of a punch and die design whilst
the shears were of two different designs (see Figure 1).

Fig1b. Shear type 1
Fig1c. Shear type 2
The nibbler design allows for both straight line and, with adjustment to the die housing, curved
cutting. Shear type 1 is only suitable for straight line cutting whilst type 2 can also
accommodate curved cutting.
Details of the seven tools tested are given in Table 1.

LABORATORY TESTING OF VIBRATION EMISSION
EMISSION TEST CODES
The current test codes for nibblers and shears are BS EN ISO 8662-10:1998 for pneumatic tools
and BS EN 60745-2-8:2003 for electric tools. These require that measurements be made in the
z-axis direction only. The more recently published BS EN ISO 20643:2005 specifies new
criteria for the design of such test codes and requires, amongst other things, that triaxial
vibration measurements are made. The change from single axis to triaxial measurement will
bring the process of emission declaration in line with the techniques for assessment of human
exposure to hand transmitted vibration as defined in BS EN ISO 5349-1:2001. The process of
modifying existing tool test codes is underway. A draft revision of BS EN 60745-2-8:2003 was
made available to HSL for the purposes of this project and was tried out as part of the project.
This is covered in more detail in section 4.1. No such revision was available for
BS EN ISO 8662-10:1998 although triaxial measurements were made. Currently applicable test
codes are summarised in Table 2.
For the purposes of comparing manufacturer’s declared emission with HSL measured emission
it was necessary to measure according to the same test codes to which the manufacturers had
declared. In the case of the electric tools this meant returning to a superseded standard,
BS EN 50144-2-8:1996. For the purposes of vibration measurement, there are no differences
between this standard and the 2003 text of EN 60745.

EMISSION TEST PROCEDURE
The methodology for BS EN ISO 8662-10 and BS EN 50144-2-8 is the same, both ultimately
requiring three series – i.e. three operators - of five consecutive tests per tool. There are minor
differences between the test procedures, the latter requiring that the tool be run in for five
minutes prior to measurement and that three series of seven consecutive tests are carried out, the
upper and lower values of these being disregarded each time and the average reading taken from
the remaining five results.
3.2.1
Method
Measurements were made on the main handle of the tool, where the operator would normally
hold the tool and apply the feed force. The location of the transducer(s) – simultaneous triaxial
measurements were made – was on the underside of the handle halfway along its length as close
as possible to the hand position between the index and the middle finger without impeding the
use of the trigger or tool. The feed force was not specified other than that the feed force applied
should ensure a stable and smooth operation of the tool. The test configuration was arranged
such that the operator was able to have and maintain an upright or almost upright posture and
work the tool cutting horizontally. During measurement, the tool cut a metal sheet of length
long enough to allow the measurements to be finalised. The cut was as near the material support
4
as the tool under test allowed. The metal sheet had the maximum thickness specified by the
manufacturer for the given material. The metal sheet used in the test was firmly secured to the
test rig and mounted such that it did not have any significant resonance in the frequency range
of interest (see Figure 2). The metal sheet was broad enough to support the tool. Three operators
carried out one test series of five runs with each tool under test. For each test run, stable tool
operation was established before measurement commenced. Measurement readings were taken
over a period of not less than four seconds. A test series was considered valid when the
coefficient of variation of the five consecutive weighted values, for the same operator, were less
than 0.15 or the standard deviation was less than 0.30 m/s2.

3.2.2
Deviations from the standard test method
3.2.2.1
Test material
The range of tools under test presented a possible range of materials to be tested. Each tool is
able to cut materials of differing specifications. It was therefore decided at an early stage in the
project to select a range of materials representative of the possibilities of the tool set and to test
each tool on as many of the test materials as possible. This would then present a range of results
for each tool. Table 3 details each tool’s cutting capacity and on which of the four chosen test
materials each tool was tested.
With different thicknesses of material, differing feed forces were required; and although the
upright posture was maintained as far as reasonably practicable throughout, the thicker materials
required a lot of effort on the part of the operators.
For all test materials, the sheet size was 0.5m x 1.0m with the shorter edge presented for cutting.
This was limited by the depth of the test bench and the width of the clamp on the test bench.
The distance of the cut from the edge of the bench varied between 0.07m and 0.11m depending
on the tool under test. This took into account the body of the tool and safe handling of the waste
material. Each cutting action removed a strip of metal 0.01m wide from the test material. After
each cut the test material was unclamped and moved to maintain the same distance from the cut
to the edge of the test bench.

3.2.2.2
Measurement period
To ensure a valid measurement, measurement periods of less than eight seconds were discarded
from the measurement series and a retest carried out. Average measurement times were
approximately 10 seconds. This varied depending on the thickness of the material and if the
operator was able to find the ‘sweet spot’ of the tool.
3.2.2.3
Left hand tool operation versus right hand tool operation
Manufacturer’s instructions are unclear as to whether tools are designed for both left and righthanded operators or whether they suit one of these better than the other. With the test bench set
up as in Figure 2a, a right-handed tool operator finds tool operation easier standing with the test
6
bench on their right due to the posture and ergonomic issues. This also applies to a left-handed
tool operator standing with the test bench on their left. This did not present an issue with the
nibblers tested or with shear type 1. However, shear type 2 cuts differently depending on which
way round it is held. This is covered in more detail in section 4.2.
3.2.2.4
Tool C’s auxiliary handle
Tool C has, as an optional extra, a hollow plastic auxiliary handle. This can be screwed into a
mounting location directly above the cutting base and reciprocating elements of the tool.
Measurements were made on the top of this handle as well as at the specified measurement
location. This is covered in more detail in section 4.3.
3.2.2.5
Tool E’s measurement locations
Tool E is the only tool where the measurement locations specified in the test code could not be
used due to the tool design. The main handle, rather than being the body of the tool, is of a
hollow plastic design. Previous HSL research has indicated that handles of a similar design and
construction may have complex modal resonances that can influence the measured vibration
data (HSL reports NV/03/08 and NV/06/18).

Fig3. Tool E’s measurement locations
Figure 3 shows where the relative ‘underneath’ and ‘on top’ measurement locations were. The
‘on top’ location was mounted using an aluminium mounting block, studs and super glue. These
locations were settled upon as the best compromise after several trial runs with the transducers
at different locations on and around the handle.
3.3
DATA ACQUISITION AND ANALYSIS
In accordance with the standard, each tool was tested with three different operators. For each
operator, five eight-second (minimum) analyses were made using a Brüel & Kjær (B&K) Pulse
multi-channel real time frequency analyser. One-third octave band analyses of the data were
carried out. The data were also frequency weighted in accordance with BS EN ISO 53491:2001 and then stored on the analyser. The overall frequency weighted vibration magnitude at
each measurement position was recorded after each test.
After five tests the coefficient of variation, Cv, was calculated. This is equal to the standard
deviation of the five measurements divided by the mean of the five measurements. The value of
Cv should be <0.15, for the data to be valid. If Cv was >0.15 then testing continued until a set of
data was produced with a Cv < 0.15.
7
For each tool, the overall arithmetic mean was obtained from the mean value for each operator.
A value for the individual deviation K, was calculated from the results of all the three operators,
according to the provisions of BS EN 12096:1997, where a single tool is used to declare the
vibration emission.
3.4
EMISSION TEST RESULTS
The full results for each of the emission tests including frequency spectra are given in
Appendices A to H. Table 4 contains the results of the HSL vibration emission measurements
made according to the test codes as declared by the tool manufacturers. These results are strictly
in terms of the z-axis direction (direction of the reciprocating action). The values reported are
the highest obtained regardless of whether the tool operation was left handed or right handed.

ADDITIONAL LABORATORY MEASUREMENTS
BS EN 60745-2-8:2003 vs EN 60745-2-8/prAA APRIL 2006
To understand the proposed revision of the electric tool test code BS EN 60745-2-8:2003 it is
also necessary to understand the proposed revision to the parent standard of this standard series,
BS EN 60745-1. The proposed revision to Clause 6.2 of the parent standard, which relates to
vibration, incorporates a complete re-write. This includes, amongst other things, references to
triaxial measurement, measurement procedure and validity and declaration of measurement.
EN 60745-2-8/prAA April 2006 incorporates three major changes:
1. Use of triaxial measurements
2. Change of measurement location from underneath the tool to on top of the tool
3. Clear description of size of test material and how much to cut for a test cycle
All three issues have been investigated during the course of this project.
4.1.1
Single axis to triaxial measurement & transducer location
Throughout the laboratory emission testing stage of this project, simultaneous triaxial
measurements on all the electric tools were made both underneath and on top of the tool (Figure
5). This allowed for direct comparison between single axis and triaxial measurement results. It
also allowed for comparison between the current measurement location and the proposed new
location.

In the majority of cases, it can be seen that the triaxial measurement on top of the tool, as per the
proposed revision of BS EN 60745-2-8, yields a higher vibration value than the triaxial
measurement made underneath the tool. In all cases, the on top triaxial measurement is equal to
or greater than both the declared and measured single axis emissions, except for tool C. This
11
difference ranges by a factor of 1.8 (tool C) to a factor of 6.5 (tool D). The large K factor
associated with tool E may be attributed to the mounting location of the transducers as discussed
in section 3.2.2.5.
4.1.2
Test material – how much to cut off
All results presented in this report relate to cutting off a 10mm strip of metal from a sheet of test
material, as described in section 3.2.2.1, unless otherwise stated. This procedure was adopted
because no guidance was available from the current test codes. This was also deemed to be best
practice to achieve maximum use of the test materials and avoid unnecessary waste. The
proposed revision to BS EN 60745-2-8 clearly states that a test cycle should consist of “cutting
off one 50mm wide strip across the 400mm width of sheet metal”. An investigation was made
into the possible effect of cutting off different width strips of metal on the measured vibration
level. Tools C and E were chosen for this investigation as the most and least repeatable tools
respectively. The test material was clamped to the test rig as for the emission testing and cuts
were made as close to the edge of the test bench as possible. Three operators were asked to use
tool C to cut off five 10mm wide strips each on test materials W and Y. They were then asked to
repeat the process for tool E. Triaxial measurements were made on top of the tool. The operators
were then asked to do the same again but to cut off 50mm strips instead.
Figures 8 and 9 show not only the variation in vibration levels for cutting off different widths of
metal on a single tool, but also the possible variations between operators for a given tool on a
given material and the possible variation in vibration levels obtainable for a single operator on a
single tool on a given material.

The results from this part of the investigation show that the amount of material to cut off for the
purpose of a repeatable laboratory test is undetermined due to the amount of variation possible.
Other influencing factors are also present including operator skill and experience, the tool and
how it cuts and the material selected. The difference seen for tool C cutting 10mm strips from
1.2mm aluminium and 2.5mm aluminium is about 30ms-2.
4.2
LEFT HAND TOOL OPERATION VS RIGHT HAND TOOL OPERATION
As highlighted in Section 3.2.2.3, manufacturer’s instructions are unclear as to whether tools are
designed for both left and right-handed use or whether they suit one of these better than the
other. The waste material from the cutting process behaves differently depending on the
direction of the cut. This is clearly shown in Figures 11a and 11b; the former shows how when
the waste material is to the right of the operator, it is a flat sheet; the latter shows that when the
waste material is to the left of the operator the waste material forms into a coil.

Example of how the same tool can be used in a right-handed operation but approaching the
material to be cut from two different directions. Fig11a is from a manufacturer’s instruction
manual; Fig11b is taken from the manufacturer’s website for the same tool.
A brief investigation was conducted using tool C (most repeatable) and test materials W and Y.
Use of the thicker test materials was attempted but was abandoned due to risk of operator injury.

As the results in Table 5 show, when used in the left hand, the vibration levels increased. It
should be noted that the three operators used in this investigation are naturally right-handed.
The rise in the vibration levels may be attributed to the operators being unaccustomed to
controlling tools with their left hand. A left-handed operator was unavailable.
4.3
TOOL C’S AUXILIARY HANDLE
Further to section 3.2.2.4, tool C has a hollow plastic handle as an optional extra (see Figure
12). The revised text for BS EN 60745-2-8 clearly states that “the result ah is the basis for the
declared value” and that “if values have been obtained for different hand positions, the greatest
value shall be the basis for the declaration”. Triaxial measurements were made on the top of the
auxiliary handle and compared to those values obtained at the revised measurement location on
top of the body of the tool. The issue of left and right hand operation was also included.

As Figure 13 shows, the total values measured on the auxiliary handle are greater than those
measured on the body of the tool. The auxiliary handle values have not, however, been used for
the purposes of comparison in this report. Previous HSL research has indicated that handles of a
similar design and construction may have complex modal resonances that can influence the
measured vibration data (HSL reports NV/03/08 and NV/06/18).
4.4
INFLUENCE OF DISTANCE OF CUT FROM EDGE OF TEST BENCH
Both BS EN ISO 8662-10 and EN 60745-2-8/prAA state that the “cut shall be as near the
support as the power tool tested allows”. The current version of BS EN 60745-2-8 does not,
however, contain this statement. Tests were carried out to investigate the influence of the
distance from the cut to the test bench on the vibration levels from an electric tool. Tool D was
used in this instance because it had the lowest declared vibration value and was favoured as the
most efficient by the operators.
Two operators were asked to make 15 consecutive cuts in a sheet of 1.2mm thick steel. Each cut
removed a 10mm slice of metal. The test bench was set up such that the steel sheet extended
180mm from the edge of the bench. As the tool operator completed a cut, the next cut was
10mm closer to the bench. The vibration levels from each cut were measured underneath and on
top of the main body of the tool. Only those levels measured on top of the tool are considered
here and are shown in Figures 14a and 14b. Full results may be found in Appendix J.
Figure 14a shows the total vibration value drop over the first four cuts. It then rises until the
final cut. Figure 14b shows a similar trend until cut 13. At this stage during measurement, the
operator had reached the edge of the test bench and had run out of material to cut. The material
was then moved out from the test bench by 30mm and cuts 14 and 15 made. The effect on the
vibration levels is clearly shown by the lower values obtained for cuts 14 and 15.

It is possible to check for continuity of measurement in the case of operator #5 due to the
repositioning of the test material for the final two cuts. Cut 13 was made 30mm from the bench;
this means that cuts 10 and 11 were made at 60mm and 50mm respectively from the edge of the
bench. This is also the case for cuts 14 and 15. Table 6 details the numerical values for Figures
14a and 14b.

The results from this investigation show that measuring the vibration level when the cut is as
near the support as the tool under test allows will give a worst-case vibration emission value. It
should be noted that the distance between the cut and the edge of the test bench will vary
between tools.

FIELD / SIMULATED REAL MEASUREMENTS
THE PLAN
Following the laboratory emission test stage of the project it was the intention to take the tools
to a number of industrial sites where nibblers and shears are used for various applications. The
vibration levels from the tools were to be measured when the tools were used during real
applications. This proved to be far more difficult than originally anticipated as the use of hand
held nibblers and shears has been gradually phased out from the shop floor environment and
replaced by mechanised processes such as plasma cutting. In addition, where once repairs may
have been made, for example, to a vehicle body panel, it is now more economical to replace the
entire panel. The tools can sometimes be seen on construction sites, for example, during the
installation of heating and ventilation systems or fitting of corrugated roof structures when a
small amount of trimming is required. However, the trigger times involved in these operations
amount to 2-3 seconds at a time, a few times a day when appropriate. When compared to
potential shop floor trigger times of a few minutes at a time, dependent on the cut being made,
the construction site trigger times become negligible.
5.2
WHAT ACTUALLY HAPPENED
One site was located where hand held shears (type 2) were still used in the workshop, along side
a plasma cutter. The site provides ventilation ductwork products and services to the
environmental engineering sector. Such ductwork and associated products are manufactured
from varying grades of galvanised steel. Typical tool usage is when access panels need to be cut
into the side of a ventilation duct (see Figures 15a and 15b). The size of the access panels, and
in turn the amount of time required to cut them, is entirely installation dependent; e.g.
300mm x 300mm to 1000mm x 1000mm. Similarly, when a curved boot saddle, sometimes
referred to as a shoe, needs attaching to a main section of duct, the hole required can vary in size
from 300mm ∅ to 1500mm ∅ and larger.
Fig15a. Closed access panel
Fig15b. Access panel with hatch removed
The test pieces available were 500mm x 500mm x 1200mm box sections of ventilation duct
constructed from 1mm thick galvanised steel. These sections had been set aside as scrap but this
was not due to any discrepancies in the grade of the material. In order to allow enough operation
time for a statistically valid measurement (>8 seconds) access panel templates of
400mm x 400mm were chosen. Three holes per duct side could be cut. To remove as many
variables as possible associated with the structural integrity of the duct sections, the three
operators were used in the same order for each tool tested and always cut their hole at the same
location on the duct (see Figure 16). The measurement conditions were kept as close to a real
work situation as possible even though these particular duct sections were not bound for an
19
installation. Triaxial measurements on each tool were made at the same locations as in the
laboratory except for tool F where the measurement location was moved to the top of the tool
and mechanical filters were added to overcome DC shift. The thickness of the test material was
within the cutting capacity for all tools and so data was obtained for all tools. It was apparent
from observation of tool usage and the operator’s comments that not all the tools were suitable
for this task. The duration of the task was typically between 30 and 60 seconds.

Of the three operators used, operators 2 and 3 were very experienced whereas operator 1 was
relatively new to the industry sector with a little shop floor experience of cutting access panels.
Operator 1 generally took more time and care over the cuts whereas operators 2 and 3 were
more forceful with the tools.
All three operators used a similar cutting technique. All three were right-handed, but constantly
swapped hands, used both hands and let go of the tool during operation. This allowed them to
work from the side of the work piece. Figures 17a to 17c show how the operators used both
hands individually and together to operate the tools. It should be noted that although the
operators let go of the tool during its use, this did not unduly affect the vibration levels; these
settled early in the average 30-second measurement period.

DATA ACQUISITION AND ANALYSIS
Data acquisition for the field / simulated real tests was as for the laboratory emission tests with
the vibration levels also being recorded to DAT. For each operator a sample measurement was
made during typical use of the tool. The data were analysed whilst on site using a B&K Pulse
multi-channel real time frequency analyser. This was configured to produce one-third octave
band frequency spectra for each axis of vibration. From these, the frequency weighted
acceleration was calculated by applying the hand arm frequency weighting as defined in
BS EN ISO 5349-1:2001 to the vibration spectra.
All of the measurements for all of the tools were used to derive a mean frequency weighted
vibration magnitude and associated standard deviation.

Channels 3 (on top) and 6 (underneath) relate to the z-axis results (direction of reciprocation).
Tools B, C, D and E had measurements made on top and underneath the tool for the reasons
outlined in sections 3.1 and 4.1. The measurement location for tools A and G was underneath
the tool. For tool F the measurement location was on top of the tool. This was due to practical
restrictions of mounting the transducer block with mechanical filters. The total values for each
measurement location are also given.
Tool C was used without its auxiliary handle. The operators commented that it got in the way of
efficient tool use.

DISCUSSION
6.1
ANALYSIS OF EMISSION DATA
6.1.1
Verification of manufacturer’s declared emission
For comparison of measured and declared emission values, EN 12096:1997 states that if one
machine is evaluated, rather than a batch, the manufacturer’s declared emission is verified if the
measured vibration emission, a, is less than, or equal to, the manufacturer’s a+K value.
Table 8 shows a comparison of the measured and declared vibration emissions for each tool.
Tools A and F were declared with a K value. For those tools without a K value, the K value in
the table has been calculated as 0.4 or 0.5 of a, in accordance with the requirements of
BS EN 12096:1997 where one machine has been tested. For the HSL measured emission, the K
value has been calculated from the individual measurements for the three test subjects, also
according to BS EN 12096:1997.
The HSL vibration emission measurements were made according to the test codes as declared
by the tool manufacturers. These results are strictly in terms of the z-axis direction (direction of
the reciprocating action). The values reported are the highest obtained regardless of whether the
tool operation was left handed or right handed.

6.1.2
Analysis of HSL measured emission – total values
Figures 18a to 21b show the measured emission total values against the standard deviation of
the measurement. Displaying the data in this way highlights the grouping of the tools. Figures
18a to 21b are grouped in pairs by test material. Figures ‘a’ show the total values measured
underneath the tool for electric and pneumatic tools. Figures ‘b’ show the total values measured
underneath the tool for the pneumatic tools and the values measured on top of the tool for the
electric tools. This does mean that the data for tools A, F and G is displayed twice.
On test materials W and Y, tool G is consistently of low vibration. This is a type 1 pneumatic
shear. Tool G does not appear on the results for materials X and Z as these are outside its
cutting capacity.
For all test materials and both measurement locations, tool D has a consistently high vibration
level in the range of 10ms-2 to 20ms-2; the standard deviation is relatively consistent, averaging
2.23ms-2. Tool D was favoured during emission testing by all operators as being the most
efficient tool.
Tools A and F are consistently grouped together at the lower end of the scale. It should be
remembered that both of these tools are pneumatically driven and were therefore not subject to
the change in measurement location experienced by the electric tools.
Tool E is anomalous. As described in section 3.2.2.5, it is the only tool where the primary
measurement locations were compromised due to the tool design. The main handle, rather than
being the body of the tool, is of a hollow plastic design. Previous HSL research has indicated
that handles of a similar design and construction may have complex modal resonances that can
influence the measured vibration data (HSL reports NV/03/08 and NV/06/18). This may
account for the large variation in measurements reflected in the large standard deviation.
Tools B and C are inconsistent, sometimes grouped with the majority of the tools, sometimes
separate.
For the electric tools it is possible to calculate the percentage increase (or decrease) in the
measured emission value due to the change in measurement location as proposed in the revised
text of BS EN 60745-2-8. This is shown in Table 9. The percentages are calculated from the
total values measured underneath and on top of the tool.

Similar graphical representation can be made using the declared emission values and their
respective K factors. This is shown in Figure 22 It can be clearly seen that tool E is separate
from all the other tools tested. The remaining tools are more or less grouped together with tool
28
G still showing as the lowest vibration tool. Interestingly, tool D is also shown as low vibration;
although this was not verified during emission testing, it was the tool favoured by all operators
as being the most efficient.

FIELD / SIMULATED REAL MEASUREMENTS
As outlined in section 5.1, the intention for this phase of the project was to take the tools
measured in the laboratory to a number of industrial sites where they are used in various
applications. The vibration levels from the tools were to be measured when the tools were used
during real applications. With a lack of suitable sites, and therefore an inherent lack of field
data, it is difficult to draw comparisons between the results from the one site that was found and
the extensive laboratory testing that was carried out. Statistical analysis in this case would be
invalid. It is however possible to show the results of the field data with certain aspects of the
laboratory testing. This is covered further in sections 6.2.1 and 6.2.2. Further applications for
the use of nibblers and shears may include the metal roofing and cladding sector and the
automotive (repair) industry, although as mentioned in section 5.1, the use of the tools appears
to be limited to installation sites and/or very short trigger times.
It should be noted that not all of the tools were suitable for the task of cutting out rectangular
pieces of metal in ductwork. Although a thin grade of galvanised steel was used (1mm), cutting
90o corners proved too much for some tools. Cutting out the access panels requires the operators
to cut at least four 90o corners. In the case of Tool D this was not possible at all. The field
results for tool D represent straight line cuts only (see Figure 23. Tool E, although managing
corners, frayed the metal. This is shown in Figure 24 The operators commented that this would
be unsatisfactory for production purposes. The operators also commented that in attempting to
cut the corners, a coaxing motion helped whereby they moved the tool in a back and forth
motion to open up the cutting area. Whilst this may aid the cutting process for shears (the blades
29
being exposed at both the front and rear), it is difficult to ascertain how this would help for
nibblers where the cutting edge of the punch is at the leading edge of the tool.
Fig23. Straight line cuts
Fig24. Frayed corners
For the tools that in the laboratory were able to cut the thicker test materials X and Z, it was not
possible to obtain additional corroborative data in the field. This is unfortunate as in the case of
tool C, a vibration magnitude in excess of 30ms-2 was observed when cutting material Z.
It was of interest to observe that the tool in use at the site was identical to tool C used in this
project. The tool in question was subjectively the most efficient and adept at performing the task
required of it at this site i.e. the right tool for the job. Where other tools required approximately
90 seconds to cut a hole, tool C required a maximum of 30 seconds.
6.2.1
Comparison of single axis emission and simulated real data
Figure 25 shows the single axis field data for each tool with both the declared emission and
relative laboratory measured emissions for test material W (1.2mm steel). For four of the seven
tools, the field data exceeded both the declared and measured emissions. For two of the seven
tools, the field data were lower; this was the case for tool G which has been consistently ranked
as the lowest vibration tool even though it was not suitable for this task. In the case of tool F,
the field data lies between the declared and measured emissions. Tool E once again
demonstrates a wide range of data possibly in part attributable to the alternative transducer
mounting locations and design of the handle. It should be remembered that the field data is for
one site, one application and one material type and is being shown for indicative purposes only.
Similarly, Figure 26 shows the declared emissions with the triaxial field and measured emission
data. For the measured emission data, the total values here represent measurement underneath
the tool for tools A, F and G and on top of the tool for B, C, D and E. For the field data, the total
values represent measurement underneath the tool for A and G and on top for tools B, C, D, E
and F.

It should be noted that the values for the tool F field data were obtained from a mounting
location on top of the tool and not underneath the tool as per the laboratory emission test. This
was due to practical restrictions of mounting the transducer block with mechanical filters. There
is no data to investigate the difference, if any, between measurements made on top of or
underneath this tool.
It is not statistically valid to investigate upper quartile values as it was not possible to obtain
sufficient field data. This is covered further in Section 6.3.
6.2.2 Comparison of triaxial emission and simulated real data – the effect of
transducer location
Figure 27 shows the triaxial data obtained for each tool under laboratory conditions and in the
field (square markers). In the case of the electric tools (B, C, D & E), triaxial data from the
proposed new measurement location on top of the tool is also shown (triangle markers).
For the pneumatic tools (A, F & G), where vibration is currently measured underneath the body
of the tool, changing to triaxial measurement is still likely to underestimate the in use values of
the tools.
For the electric tools, the change to triaxial measurement and measuring on top of the tool is
likely to overestimate the in use values of the tools.
Table 11 details the numerical values for Figure 27.

EMISSION VALUES AS AN INDICATOR OF RISK
One of the requirements of BS EN ISO 20643:2005 is that new test codes for vibration emission
of machines should both measure the total value of the frequency weighted vibration (derived
from the root-sum-of-squares of the vibration in three axes) and be designed to produce
emission values which correspond to the upper quartile of vibration magnitudes resulting from
intended uses of the machinery. In this case it was not statistically valid to calculate the upper
quartile values to then be able to assess the suitability of the emission test standard. This is
because it was only possible to locate one site where the tool type was still in use in a workshop
environment. As Figures 25 and 26 show, it is possible to gain an initial insight as to how field
data may vary from emission test data.
It is however possible to show the ratio of the measured a emission total value to the mean field
total value. This is shown in Figure 28. A ratio of 1 is achieved if the a emission and mean field
values are the same. The value of 1 on the y-axis may be considered as the target value. The
error bars on each tool represent the difference that the K value makes to the ratio.
Points below the value of 1 indicate that the emission data underestimate the field data. Points
above the value of 1 indicate that the emission data are over estimated.
Details of measurement locations on the tools are given in Table 12.

Figure 28 shows that for tools A, F and G, the measured emission total value underestimates the
mean field total value even when the K value is included. These three tools are all pneumatic.
For tools B, C, D and E the measured emission value is either equal to or overestimating the
mean field value. These tools are all electric and the emission and field total values obtained in
accordance with the proposed draft revision to the electric tools standard (EN 60745-2-8/prAA
April 2006). This confirms the results shown in Figure 26.
6.4
TOOL EFFICIENCY
It is possible to look at an example of tool efficiency against a lower vibration, but less suited,
tool for a particular task. Tool G has consistently ranked as the lowest vibration tool during this
project. This was also the case for the field data, even though the tool was not suited to the task
in hand. Tool C was the same model as used by the field site. Using vibration total values for
each of the tools it is possible to calculate an operator’s partial exposure based on the field data,
the HSL measured emission and the manufacturer’s declared emission. Table 13 shows the
results from HSE hand-arm vibration exposure calculator.

As may be seen from Table 13, if the field data is considered, the partial exposure doubles for
tool G. If, however, emission data were used to estimate daily exposure, both the HSL measured
values and the manufacturer’s declared values give identical partial exposures. This highlights
the issue that the lowest vibration tool isn’t necessarily the most suitable tool for the task. It also
35
shows that the manufacturer’s single axis data potentially underestimates exposure by up to a
factor of four in this instance.

CONCLUSIONS
The main findings of the research are as follows:
1. Manufacturer’s declared emission values as measured according to BS EN ISO 866210:1998 and BS EN 50144-2-8:1996 (predecessor to BS EN 60745-2-8) were verified
according to the criteria in BS EN 12096:1997 in 4 out of 7 cases; 2 out of 7 cases were not
verifiable. The remaining case was partially verified dependent on the test material and
direction of operation.
2. The current standard test methods do not specify one particular test material or a range of
test materials. It is therefore unclear to what type of material the manufacturer’s declared
emissions relate. This research has shown that for one tool cutting three different types of
material, the total vibration value can vary by up to 30ms-2.
3. Based on the data in this study, single axis a emission values may be lower than the total
triaxial a emission values by up to 62.2%.
4. There is great potential for vibration levels to vary between materials, operators, tools and a
combination of all three factors. Operator skill and experience also play a role.
5. The amount of material to cut off for the purpose of a repeatable and reproducible
laboratory test is undetermined due to the amount of variation possible. Varying the width
of material to cut off introduces another variable into an already complex situation. The
specifications in EN 60745-2-8/prAA will help.
6. For electric tools, the triaxial transducer locations on top of the tool in EN 60745-2-8/prAA
will yield a higher vibration value than the current standard test (single axis underneath the
tool). For pneumatic tools, BS EN ISO 8662-10 (transducers located underneath the tool)
triaxial measurement will yield a higher vibration value than the current single axis
requirement.
7. Transducer location influences vibration magnitudes. For electric tools, EN 60745-28/prAA overestimates the mean in-use values (transducers on top). For pneumatic tools,
BS EN ISO 8662-10 underestimates the mean in-use values (transducers underneath). End
users of the tools are at risk of not being in possession of data representative of vibration
hazard.
8. It was not possible to investigate in-use values in terms of emission upper quartile data due
to a lack of field sites.
9. The current test methods do not take the efficiency of the tool into account. Vibration data
should not be used in isolation to identify the best tool for a particular application.
Consideration must also be given to the rate of work achieved and suitability for the
application.
10. Tools with plastic handles, whether the main handle or an auxiliary handle, can resonate
which influences measured vibration data. This can be identified by unrealistically high
and/or wide ranging measured vibration data e.g. tool E has a total value range of 22.7ms-2
to 40ms-2.
11. Measuring the vibration level when the cut is as near the test bench as the tool under test
allows will give a worst-case scenario i.e. gives the highest value.

Correlation between vibration emission
and vibration during real use
Nibblers and shears
The aims of the work reported here were:
■
■
■
■
To assess the BS EN ISO 8662­10 (pneumatic tools)
and the BS EN 60745­2­8 (electric tools) emission
test for usability and repeatability.
To assess reproducibility by comparing our results
with manufacturers' declared vibration emission
values (and verifying in accordance with
BS EN 12096).
To compare vibration emission values with vibration
magnitudes measured under real operating
conditions.
To assess vibration emission data as an indicator of
vibration hazard. This report and the work it describes were funded by
the Health and Safety Executive (HSE). Its contents,
including any opinions and/or conclusions expressed, are
those of the author alone and do not necessarily reflect
HSE policy.
