Foreword
The text of the International Standard IEC 60745-2-2:2003, prepared by SC 61F (transformed into
IEC TC 116, Safety of hand-held motor-operated electric tools), together with the common modifications
prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116) was submitted to the
Unique Acceptance Procedure and was approved by CENELEC as EN 60745-2-2 on 2002-12-01.
A number of amendments to EN 60745-2-2 have since been voted on and published as amendments
A11, A1 and A12.
A further draft amendment (FprAD) including improvements to the vibration test code was submitted to
the Unique Acceptance Procedure.
The combined texts were approved by CENELEC as a new edition of EN 60745-2-2 on 2010-02-01.
This European Standard supersedes EN 60745-2-2:2003 + A11:2007 + A1:2009 + A12:2009.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2011-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2013-02-01
This 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.
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 supports the essential health and
safety requirements of the Machinery Directive 2006/42/EC. See Annex ZZ.
Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with
the essential health and safety requirements of the Directives concerned.
CEN/TC 255 is producing standards for non-electric screwdrivers and impact wrenches (EN 792-6).
Warning: Other requirements and other EC Directives can be applicable to the products falling within
the scope of this standard.
The standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2.
This Part 2-2 is to be used in conjunction with EN 60745-1:2009. When this standard states "addition",
"modification" or "replacement", the relevant text in Part 1 is to be adapted accordingly.
Subclauses and figures which are additional to those in Part 1 are numbered starting from 101.
Annexes, subclauses, tables and figures which are additional to those in IEC 60745-2-2 are prefixed “Z”.

6.1.2.5 Modification:
Screwdrivers are tested at no-load.
Impact wrenches are tested under load. The load is applied by means of a brake system, so that the
-1
and the impact mechanism is caused to
socket driving the brake rotates at a test speed of (45 ± 5) min
operate continuously. The brake as shown in Figure Z101 is supported on a resilient material and
mounted on a bench such that the geometric centre of the tool is 1 m above the reflecting plane. The
details of the brake system are given in EN ISO 28927-2:200X, Annex C.
To prevent chattering noise from items 2, 3 and 5 of the brake shown in EN ISO 28927-2:200X,
Figures C.1 and C.2, these parts may be insulated between each other by material such as rubber.
The feed force shall be just sufficient to obtain a stable operation.
The measurement time shall be approximately 10 s.
6.2 Vibration
6.2.4.2 Location of measurement
Addition:
Figures Z102 and Z103 show the positions for different screwdrivers and impact wrenches
6.2.6.3 Operating conditions
Modification:
Table Z101 — Operating conditions for screwdrivers without impact mechanism
Orientation Screwdrivers are tested at no-load.
The screwdriver is hold horizontally during the test.
Tool bit
Tool bit of medium length and size.
Grip force Hold the machine with normal gripping force, avoiding excessive gripping force.
Test cycle One test cycle is given when the tool is switched on for no load at max. speed for more than 10 s and
then switched off again.
The measurement is conducted during 10 s within this period.
NOTE As it is difficult to measure load applications of screwdrivers in laboratories and results have shown that the load has no
influence on the vibration results, the measurements are conducted with no-load only.

Table Z102 — Operating conditions for screwdrivers with impact mechanism and impact wrenches
Orientation The tools are tested under load.
Either a hexagon head bolt is screwed into a nut or a hexagon nut is screwed onto a bolt using a
steel plate as part of a test fixture according to Figure Z104. The test fixture shall be either mounted
on the floor or on a concrete block at least the size of the test fixture with a minimum thickness of
200 mm.
NOTE Figure Z104 shows an example for mounting the test fixture.
The bolts or nuts are of the biggest capacities of the tool under test. The screw case is a hard joint
with one steel washer under the head. The initial setting of the bolt or nut shall provide 10 mm of
exposed length from the steel plate to provide the run up. The test fixture shall not turn or move
during the test.
The steel plate shall be long enough to accept 5 fixings with a clearance between each fixing of at
least the dimension of the head of the bolt or nut or a dimension distance which does not cause
interference with the adjacent fixing.
Tool bit Hex head sockets of the size and depth needed for the bolts or nuts defined above.
Feed force Provide sufficient grip and feed force to maintain safe control. Avoid excessive grip and feed force.
Test cycle The test cycle will be one fixing for the specified bolt or nut for a period of run down and 5 s from
first impact (one test series contains five cycles).
The measurement starts from switch on of the tool with the socket / bit engaged with the bolts or
nuts to the end of 5 s of impact with continuous operation. This includes the time to cover run up of
10 mm.
6.2.7.2 Declaration of the vibration total value
Addition:
The vibration total value a of the handle with the highest emission and the uncertainty K shall be
h
declared and:
− for screwdrivers usable without impact
the work mode description “screw driving without impact”;
− for screwdrivers with impact mechanism and impact wrenches
the work mode description “impact tightening of fasteners of the maximum capacity of the tool”.
