Overview

EN 60745-1:2006 - "Hand‑held motor‑operated electric tools - Safety - Part 1: General requirements" (CLC / CENELEC) is the European adoption of IEC 60745‑1 that sets general safety and test requirements for hand‑held motor‑operated or magnetically driven electric tools. It covers tools with rated voltages up to 250 V (single‑phase a.c. or d.c.) and 440 V (three‑phase a.c.) and addresses common hazards in normal use and reasonably foreseeable misuse. Part 1 establishes the baseline safety, while separate Part 2 documents address specific tool types.

Key Topics

• Scope and conformity: Defines how Part 1 works with Part 2 to meet essential health and safety requirements of the EU Machinery Directive.
• Safety principles: General design and construction requirements to reduce risks for operators and bystanders in typical use and foreseeable misuse.
• Environmental requirements - Noise:
  • Noise reduction at source is emphasized as part of design.
  • Prescribed noise test code (grade 2) and measurement procedures (sound power and emission sound pressure).
  • Use of EN ISO 3744 and EN ISO 11203 methods, A‑weighted sound power levels (dB(A)), and reporting of uncertainties.
  • Measurement geometry: hemispherical/cylindrical surface with five microphone positions at 1 m from the tool’s geometric centre; declared correction Q = 11 dB for workstation sound pressure level.
• Testing conditions: Specifies tool mounting, operating conditions (no‑load/load), measurement intervals and averaging (3 or 5 runs), and reproducibility expectations.
• Vibration and acoustic considerations: Normative references added for measurement and declaration of vibration and noise emission values.

Practical Applications

• Manufacturers use EN 60745‑1 to design safer hand‑held tools, implement noise‑reduction measures, and prepare compliant user information and noise declarations.
• Test laboratories apply the specified measurement geometry and procedures when determining sound power and emission levels for product certification.
• Compliance engineers and CE marking teams rely on this standard (together with relevant Part 2) to demonstrate conformity with the Machinery Directive.
• Procurement and safety managers use declared noise and vibration data to assess tools for workplace risk assessments and purchase decisions.

Related Standards

EN 60745‑1 references and aligns with a number of standards, for example:

• EN ISO 3744 (sound power)
• EN ISO 11203 (emission sound pressure at workstation)
• EN ISO 4871 (noise declaration)
• EN ISO 5349 / EN ISO 20643 (hand‑transmitted vibration)
• EN ISO 11688‑1 and EN ISO 11690‑3 (low‑noise design and workplace noise prediction)
• EN ISO 8041 (vibration instrumentation)

Using EN 60745‑1 helps ensure robust safety design, repeatable acoustic testing, and clearer product declarations for hand‑held power tools.

This European Standard has been prepared under a mandate given to CEN and CENELEC by the
European Commission and the European Free Trade Association and covers essential health and
safety requirements of the Machinery Directive.
Compliance with the clauses of Part 1 together with a Part 2 provides one means of conforming to
the essential health and safety requirements of the Directive concerned.
A relevant Part 2 is one in which the type of the tool or an accessory which is to be used with the
tool is within the scope of that Part 2.
When a relevant Part 2 does not exist, Part 1 can help to establish the requirements for the tool,
but will not by itself provide a means of conforming to the relevant essential health and safety
requirements of the Machinery Directive.
Other standards referred to in this European Standard are also listed in Clause 2, which gives the
valid edition of those documents at the time of issue of this EN.
CEN Technical Committees have produced a range of standards dealing with a similar range of
non-electrically powered tools. Where necessary normative references are made to these
standards in the relevant Part 2.
This European Standard follows the overall requirements of EN ISO 12100-1 and
EN ISO 12100-2.
This European Standard is divided into two parts:
Part 1: General requirements which are common to most hand-held electric motor operated tools
(for the purpose of this standard referred to simply as tools) which could come within the
scope of this standard;
Part 2: Requirements for particular types of tools which either supplement or modify the
requirements given in Part 1 to account for the particular hazards and characteristics of
these specific tools.

6 Environmental requirements
6.1 Noise
6.1.1 Noise reduction
Noise reduction at tools is an integral part of the design process and shall be achieved by
particularly applying measures at source to control noise, see for example EN ISO 11688-1. The
success of the applied noise reduction measures is assessed on the basis of the actual noise
emission values in relation to other machines of the same type with comparable non acoustical
technical data.
The major sound sources of tools are: motor, fan, gear.
6.1.2 Noise test code (grade 2)
6.1.2.1 General
Noise emission values like the emission sound pressure level L and the sound power level
pA
L to be quoted in the user instructions as required by 8.12.2 Za)1) shall be measured according
WA
to the test procedure described in 6.1.2.1 to 6.1.2.6.
The overall noise can be divided into the pure machine noise and the noise of processing the
workpiece. Both are influenced by the method of operation, however for percussive tools the
noise emission of the workpiece can be dominant. The load conditions for particular tools are
therefore specified in the relevant Part 2.
Noise emission values obtained under these measurement conditions will not necessarily
correspond to the noise levels produced under the operational conditions of practical use.
NOTE It is not possible to simulate all conditions of practical use. A statement of process noise could
therefore
- be misleading and cause faulty assessment of the risk in individual cases,
- discourage the development of more silent machines,
- lead to low repeatability of measurements and thus cause problems when verifying declared noise values,
- make the comparison of the noise emission from different tools difficult.
6.1.2.2 Sound power level determination
The sound power level shall be measured according to EN ISO 3744, where the acoustic
environment, instrumentation, quantities to be measured, quantities to be determined, and the
measurement procedure are specified.
The sound power level shall be given as A-weighted sound power level in dB reference 1 pW. The
A-weighted sound pressure levels, from which the sound power is to be determined, shall be
measured directly, and not calculated from frequency band data. Measurements shall be made in
an essentially free field over a reflecting plane.
For all hand-held electric power tools, the sound power level shall be determined by using a
hemispherical / cylindrical measurement surface according to Figure Z2.
The hemispherical / cylindrical measurement surface is described by a hemisphere standing on a
cylindrical pedestal (see Figure Z2). Five microphone positions shall be located 1 m from the
geometric centre of the power tool. Four positions shall be spaced at regular intervals on a plane
defined as passing through the geometric centre of the power tool and parallel to the reflecting
plane; the fifth position shall be located at a distance of 1 m above geometric centre of the power
tool.
The A-weighted sound power level, L , shall be calculated, in accordance with Subclause 8.6 of
WA
EN ISO 3744 as follows :

L = L +10lg( ) , in dB (Z1)

For the hemispherical / cylindrical measurement surface shown in Figure Z2, the area S of the
measurement surface is calculated as follows:
S = 2π(R + Rd) , in m. (Z2)
where
d = 1 m is the height of the distance of the geometrical centre of the power tool above the
reflecting plane
and
R = 1 m is the radius of the hemisphere and of the cylinder which comprise the measurement
surface.
Therefore,
S = 4π m ,
so, from equation (Z1)
L = L +11, in dB. (Z3)
WA pfA
6.1.2.3 Emission sound pressure level determination
The A-weighted emission sound pressure level at the work station, L , shall be determined in
pA
accordance with EN ISO 11203 as follows:
L = L −Q , in dB (Z4)
pA WA
where
Q = 11, in dB
- 7 - EN 60745-1:2006
NOTE 1 This value of Q has been determined, during experimental investigations, to be applicable to hand-held power
tools. The resulting A-weighted emission sound pressure level at the workstation is equivalent to the value of the surface
sound pressure level at a distance of 1 m from the power tool. This distance has been chosen to give satisfactory
reproducibility of results, and to permit comparison of the acoustic performance of different hand-held power tools which
do not, in general, have uniquely defined work stations. Under free field conditions, where it may be required to estimate
the emission sound pressure level, L , at a distance r in m from the geometric centre of the power tool, this may be
pA1 1
done by applying the formula :
L = L + 20 lg ( ), in dB
pA1 pA
r
NOTE 2 At any given position in relation to a particular machine, and for given mounting and operating conditions, the
emission sound pressure levels determined by the method of this European Standard will in general be lower than the
directly measured sound pressure levels for the same machine in the typical workroom where it is used. This is due to
the influence of sound reflecting surfaces in the workroom compared to the free field conditions of the test specified here.
A method of calculating the sound pressure levels in the vicinity of a machine operating alone in a workroom is given in
EN ISO 11690-3. Commonly observed differences are 1 dB to 5 dB, but in extreme cases the difference may be even
greater.
If required, the C-weighted peak emission sound pressure level L shall be measured at each
pCpeak
of the five measurement positions specified in 6.1.2.2. The C-weighted peak emission sound
pressure level at the work station is the highest C-weighted peak sound pressure level measured
at any of the five microphone positions; no corrections are permitted.
6.1.2.4 Installation and mounting conditions of the power tools during noise tests
The installation and mounting conditions shall be the same for the determination of both sound
power level and emission sound pressure level at the work station.
The power tool under test shall be new and equipped with accessories which affect the acoustic
properties, as recommended by the manufacturer. Prior to commencing testing, the power tool
(including any required ancillary equipment) shall be set up in a stable condition in accordance
with the manufacturer’s instructions for safe use.
The tool is held by the operator or suspended in such a way as to correspond to normal use, as
specified in the relevant Part 2.
o
If the power tool is used horizontally, it shall be positioned so that its axis is at 45 between the
microphone positions 1 - 4 and 2 - 3; its geometrical centre shall be 1 m above the ground
(reflecting plane). If these requirements are impracticable or the tool is not used horizontally, the
adopted positions shall be recorded and described in the test report.
The operator shall not be positioned directly between any microphone position and the power tool.
6.1.2.5 Operating conditions
The operating conditions shall be identical for the determination of both sound power level and
emission sound pressure level at the work station.
Measurements shall be carried out on a new tool.
Tools are tested under the two operating conditions “no load” or “load” as appropriate for the type
of tool and specified in the relevant Part 2. Before starting the test, the tool shall be operated
under these conditions for a period of at least 1 min.
A measurement under “load” is to be carried out during processing of a workpiece or under
external mechanical load equivalent to normal operation.
Where tests are required to be carried out on a bench it shall be in accordance with the test bench
shown in Figure Z1.
Care shall be taken that the location of the work piece on its support does not adversely affect the
result of the test. If necessary, or when specified in the Part 2, the work piece shall be supported
on a resilient material 20 mm thick compressed to 10 mm under the weight of the work piece.
Three consecutive tests for no-load or five for load shall be carried out and the result of the test
L shall be the arithmetic mean, rounded to the nearest decibel, of the three or five tests.
WA
During measurements, the power tool shall operate under stable conditions. Once the noise
emission is steady, the measurement time interval shall be at least 15 s, unless the operating
conditions specified in the relevant Part 2 do not require another time interval. If measurements
are to be made in octave or one-third octave frequency bands, the minimum period of observation
shall be 30 s for the frequency bands centred on or below 160 Hz, and 15 s for the frequency
bands centred on or above 200 Hz.
6.1.2.6 Measurement uncertainties
A standard deviation of reproducibility of less than 1,5 dB is expected for the A-weighted sound
power level determined according to EN ISO 3744 and the A-weighted emission sound pressure
level determined according to EN ISO 11203.
6.1.2.7 Information to be recorded
The information to be recorded covers all of the technical requirements of this noise test code.
Any deviations from this noise test code or from the basic standards upon which it is based are to
be recorded together with the technical justification for such deviations.
6.1.2.8 Information to be reported
The information to be included in the test report is at least that which is required to prepare a
noise declaration or to verify the declared values. Thus as a minimum the following information
shall be included:
− reference to this noise test code and to the basic standards used;
− description of the power tool;
− description of the mounting and operating conditions;
− the noise emission values obtained.
It shall be confirmed that all requirements of the noise test code have been fulfilled, or, if this is
not the case, any unfulfilled requirements shall be identified. Deviations from the requirements
shall be stated and technical justification for the deviations shall be given.
6.1.2.9 Declaration and verification of noise emission values
The declaration of the noise emission values shall be a dual number according to EN ISO 4871. It
shall declare the noise emission value L (L , L and L ) and separately the respective
pA pCpeak WA
uncertainty K (K , K and K ).
pA pCpeak WA
For a standard deviation of reproducibility of 1,5 dB and for a typical standard deviation of
production, the values for the uncertainty, K , K and K respectively, are expected to be
pA pCpeak WA
3 dB.
The noise declaration shall state that the noise emission values have been obtained according to
this noise test code. If this statement is not true, the noise declaration shall indicate clearly what
the deviations from this standard, and from the basic standards, are.
NOTE If the measured value is the average based on a sample of three power tools that has been properly sampled,
then K normally is 3 dB. Further guidance on sampling and uncertainty terms is given in EN 27574-4 and EN ISO 4871.
Additional noise emission quantities may also be given in the declaration.

- 9 - EN 60745-1:2006
If undertaken, the verification shall be performed for a batch of power tools, in accordance with
Subclause 6.3 of EN ISO 4871. The verification shall be conducted by using the same mounting,
installation and operating conditions as those used for the initial determination of noise emission
values.
6.2 Vibration
6.2.1 Vibration reduction
The vibration at the handles shall be kept as low as possible without unduly affecting the
performance and the ergonomics (weight, handling, etc.) of the tool.
In particular vibration shall be reduced by the application of engineering measures as given in
CR 1030-1. The success of the applied vibration measures is assessed by comparing the
vibration levels for the tool with those for other tools of the same type and with a comparable
specification and performance.
6.2.2 Vibration measurement - General
Details for particular types of tools are given in the relevant Part 2. The test code gives all the
information necessary to carry out efficiently the determination, declaration and verification of the
vibration emission characteristics. It shall allow comparison of test results for different tools.
EN 12096 gives guidance on how to declare the vibration emission values of machinery, and
specifies requirements for verification of declared values.
The vibration levels for hand-arm vibration a to be quoted in the user instructions, as required by
h
8.12.2 Za)3) shall be measured in accordance with the following test procedure.
The uncertainty K is provided as an indication of the measured deviation from the mean during
the test.
The measurement and assessment of human exposure to hand-transmitted vibration in the
workplace is given in EN ISO 5349-1 and EN ISO 5349-2.

6.2.4 Characterisation of vibration
6.2.4.1 Direction of measurement
Vibration transmitted to the hand is related to the three orthogonal directions X, Y and Z as shown
in Figure Z3. For particular types of tools, these directions may be defined in the relevant Part 2.
6.2.4.2 Location of measurement
Measurements shall be made in three directions at each hand position. All measurements shall be
conducted simultaneously.
Measurements shall be carried out as close as possible to the hand between the thumb and the
index finger, where an operator normally holds the machine.
If gripping areas are covered by soft surface material, precaution shall be taken to avoid
resonance effects of the transducer mounting. If soft surface material is provided in the gripping
area it shall be removed or strongly compressed by a transducer mounting clamp or suitable
adaptor.
In the case of vibration isolated handles the location of measurement can influence the vibration
significantly. If the transducer cannot be placed half way along the length of the handle, the points
of measurement shall be left and right to the hand to determine the relevant vibration over the
gripping area (see Figure Z3a). In this case, the test result for this handle is the average of the
results of these two measurement positions.
NOTE 1 E.g. at vibration-isolated handles of grinding machines, the vibration changes significantly over the length of
the gripping zone.
NOTE 2 The above paragraph is under review.
The measurement positions for particular types of tools are specified in the relevant Part 2.
When machines are operated with more than one grip or grasping surface, the vibration at the
hand positions where an operator normally holds the tool during normal operation shall be
measured and recorded. If it can be shown that the vibration magnitude at one grip is always
dominant, the vibration test code may specify that measurements are made only at that gripping
zone.
- 11 - EN 60745-1:2006
6.2.4.3 Magnitude of vibration
The quantity used to describe the magnitude of vibration shall be the frequency-weighted
acceleration a in m/s².
hw
Frequency weighting in accordance with EN ISO 5349-1 shall be used.
The r.m.s. value a in accordance with this European Standard is defined as the r.m.s. value of

An integrating device equipped with linear integration facilities shall be used in order to obtain
r.m.s. values of signals substantially varying with time.
The measurement time shall be as long as reasonably possible and normally not less than 8 s for
hand-transmitted vibration measurements.
If the measurement time of 8 s for individual machines is not possible, e.g. because of short
duration of operation (defined in 6.2.6.3), this shall be specified in the relevant Part 2 of this
standard.

6.2.5.1 General
The vibration measurement equipment shall be in accordance with EN ISO 8041.
Instrumentation for measuring other parameters (e.g. for controlling the working conditions),
whose characteristics are not covered by EN ISO 8401, shall be specified in the relevant Part 2.
6.2.5.2 Transducers
6.2.5.2.1 Specification of transducers
The vibration values as specified in 6.2.4.3 shall be measured using transducers and other
appropriate measurement equipment conforming to EN ISO 8041.
The total mass of the vibration transducer and its mounting shall not be sufficient to influence the
measurement result and shall not be more than 5 g for each direction of measurement.
NOTE Lightweight plastic handles are an example, where heavy transducers may not be suitable. See EN ISO 5349-2
for further information.
Factors such as the transverse sensitivity (less than 10 %), the ambient temperature range, the
typical temperature transient sensitivity and the maximum shock acceleration shall be considered
in the selection of transducers.

6.2.5.2.2 Fastening of transducers
Guidance on mounting of transducers is given in EN ISO 5349-2. The transducer and the
mechanical filter, if used, shall be mounted rigidly and on the vibrating surface.
Mechanical filters or other appropriate means may be needed to minimize measurement errors
likely to occur when measuring vibration containing impulsive elements, such as occur in
percussive tools. For more details, see EN ISO 5349-2.
NOTE High acceleration in the high-frequency components of the vibration can cause the transducer to generate false
signals (e.g. dc shift) in the frequency range of interest because of excitation of the resonance of the transducer itself.
6.2.5.3 Calibration of the measurement chain
The whole measurement system shall be checked both before and after a sequence of
measurements using a calibrator which produces a known acceleration at a known frequency.
The transducers shall be calibrated in accordance with ISO 5347 and ISO 16063-1. The whole
measurement system shall be checked according to the requirements in EN ISO 8041.
6.2.6 Testing and operating conditions of the machinery
6.2.6.1 General
Measurements shall be carried out on a new tool that is only used for the noise and vibration tests
required by this standard.
When the test procedure is not provided in a relevant Part 2 or there is no relevant Part 2, the
operating conditions and working procedure shall be specified in sufficient detail as to achieve
appropriate reproducibility. Test procedures based on a typical real working situation are
preferred. The vibration test may simulate a single phase of a task or a working cycle, consisting
of a set of operations where the operator is being exposed to vibration.
If for reasons of better reproducibility a simulated work condition is defined, the vibration source
shall produce approximately the same magnitude of vibration as that in a typical working situation.
If necessary to provide realistic emission levels, tests shall be carried out under more than one
operating condition or set of operating conditions as defined in the relevant Part 2.
If the machinery is equipped with means or devices to reduce the vibration emission in
comparable operating conditions, these shall be used, in accordance with the user instructions,
during vibration testing. If this requires a deviation from the type test method, this shall be
reported and explained in the test report.
During the measurements the hands of the operator shall guide the machine as is necessary by
the design of the tool and as specified in the instructions supplied with the machine.
6.2.6.2 Attachment, workpiece and task
The attachment or accessories to be used with the machine shall be as recommended in the user
instruction.
If these attachments are of a vibration reduction type, it shall be reported together with the
declared vibration value.
Care shall be taken that the location of the work piece on its support does not affect the results of
the test. Details for task and work piece are given in the relevant Part 2.
NOTE It should be noted that even small differences in size, shape, material, wear, unbalance, etc. of the accessory
can alter the vibration magnitude considerably.

- 13 - EN 60745-1:2006
6.2.6.3 Operating conditions
Tools are tested under load only, unless the operating condition no-load is considered as
important in practical use (no-load accounts for more than 20 % of the time when tool is switched
on). In this case the tool shall be tested under both load and no-load condition, or at a typical work
cycle containing load and no-load. The relevant Part 2 describes the modes of operation and the
calculation of the declared emission value.
The machine shall be operated at normal working conditions and working modes according to the
user instructions, which shall be maintained for the duration of the test. Those operating
conditions shall be used that are representative of the highest vibration values likely to occur at
typical and normal use of the machine under test. The measurement may be carried out by
processing a work piece or under external mechanical load equivalent to normal operation.
Before starting the test, the tool shall be operated under these conditions of at least 1 min to
warm it up.
6.2.6.4 Operator
The vibration of the machine is influenced by the operator. The operator shall therefore be skilled
and able to operate the machine properly, i.e. he shall be experienced in the use of the tool.
The gripping force shall be as under long term working conditions and not be excessive.
6.2.7 Measurement procedure and validity
6.2.7.1 Reported vibration value
Three series of five consecutive tests shall be carried out using a different operator for each
series. If it can be shown that the vibration is not affected by operator characteristics, it is
acceptable to perform all 15 measurements with one operator only. Details are specified in the
relevant Part 2.
The measurements are made in three axes and the results of each direction shall be combined
using equation (Z6) to obtain the vibration total value a .
hv
If the coefficient of variation C of the five vibration total values a , recorded for each series, is
V hv
less than 0,15 or the standard deviation s is less than 0,3 m/s², the results are accepted
N–1
(Annex ZB provides information on possible sources of errors of measurement).
The measurement result a shall be determined as the arithmetic mean of vibration total values
h
over the tests and operators.
6.2.7.2 Declaration of the vibration emission value
The result a is the basis for the declared value. If values have been obtained for different hand
h
positions, the greatest value shall be the basis for the declaration.
If required by the relevant Part 2, the work mode description corresponding to the vibration
emission shall be stated next to each declared value.

To determine the uncertainty K of the declared value according to EN 12096, the following
formula shall be used that takes the standard deviation into account:
K = 1,65 s or K = 1,5 m/s² , whatever is higher
R
n
s = (a − a )
R hvi h
∑
n −1
i=1
with
s = standard deviation (considered equal to σ )
R R
n = 3 (number of operators)
a = average vibration total value of each operator (= result for each operator)
hvi
a = average vibration total value of all measurements (= test result)
h
The vibration value(s) a shall be declared as follows:
h
Vibration total values (triax vector sum) determined according to EN 60745:
Work mode description 1 Vibration emission value a = . m/s²
h
(if required by the relevant Part 2)
Uncertainty K = … m/s²
Work mode description 2 Vibration emission value a = . m/s²
h
(if required by the relevant Part 2)
Uncertainty K = … m/s²
6.2.8 Measurement report
The report shall, as a minimum, include the following information:
a) reference to this standard including any relevant Part 2;
b) specification of the machine tested (i.e. manufacturer, type and serial number of the machine,
etc.);
c) attachment or accessories;
d) operating and testing conditions (voltage, feed force, speed setting, duration and number of
test runs, etc.);
e) measuring institution (e.g. laboratory, manufacturer);
f) date of measurement and name of the person responsible for the test;
g) instrumentation (transducer mass, filters, integrators, recording system, etc.);
h) position and fastening of transducers, measuring directions and individual vibration values
when relevant (e.g. recorded by photos);
i) the arithmetic mean total vibration a , for each operator the total vibration value a and the
h hv
three single axis weighted acceleration values a . It is good practice to report all the
hw
measured values (i.e. for all axes of vibration, tests and operators);
j) the uncertainty K of the vibration total value a .
h
Any deviations from the vibration test code in this standard shall be reported together with the
technical justification for such deviations.
