HAND-HELD MOTOR-OPERATED ELECTRIC TOOLS –
SAFETY –

Part 2-2: Particular requirements for screwdrivers
and impact wrenches



FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60745-2-2 has been prepared by subcommittee 61F: Safety of
hand-held motor-operated electric tools, of IEC technical committee 61: Safety of household
and similar electrical appliances.
Main changes include Clause 12: Heating, introducing slightly different test cycles, Clause 17:
Endurance, introducing both a no-load test and a practical test, and Clause 14: Supply
connection and external flexible cords, in respect to minimum cable specifications. Subclause
2.2.23 has been removed, as the definitions of “normal load” are now generally covered by
Part 1.
This consolidated version of IEC 60745-2-2 consists of the second edition (2003) [documents
61F/461/FDIS and 61F/485/RVD] and its amendment 1 (2008) [documents 61F/732/FDIS and
61F/752/RVD].
The technical content is therefore identical to the base edition and its amendment and has
been prepared for user convenience.

8 Marking and instructions
This clause of Part 1 is applicable, except as follows:
8.12.1.1 Addition
– Hold power tool by insulated gripping surfaces, when performing an operation
where the fastener may contact hidden wiring or its own cord. Fasteners contacting a
"live" wire may make exposed metal parts of the power tool "live" and could give the
operator an electric shock.
9 Protection against access to live parts
This clause of Part 1 is applicable.
10 Starting
This clause of Part 1 is applicable.
11 Input and current
This clause of Part 1 is applicable.
12 Heating
This clause of Part 1 is applicable, except as follows:
12.4 Replacement:
The tool is operated intermittently for 30 cycles or until temperatures stabilise, whichever is
achieved first, each cycle comprising a period of continuous operation of 30 s and a rest
period of 90 s with the tool switched off, the tool loaded during the periods of operation by
means of a brake adjusted so as to attain rated input or rated current. The temperature rises
are measured at the end of the “on” period. At the manufacturer’s option the tool may be
operated continuously until thermal stabilisation.
The impact mechanism may be disabled during the test to prevent damage to the brake.
13 Leakage current
This clause of Part 1 is applicable.
14 Moisture resistance
This clause of Part 1 is applicable.
15 Electric strength
This clause of Part 1 is applicable.

16 Overload protection of transformers and associated circuits
This clause of Part 1 is applicable.
17 Endurance
This clause of Part 1 is applicable, except as follows:
17.2 Replacement:
For screwdrivers, the test of Part 1 is applicable.
For impact wrenches, replace the test of Part 1 as follows:
Impact wrenches are operated intermittently for 12 h at a supply voltage equal to 1,1 times
rated voltage and then for 12 h at a supply voltage equal to 0,9 times rated voltage.
The tool may be switched on and off by means of a switch other than that incorporated in the
tool.
Each cycle of operation comprises an “on” period of 100 s at no load and a resting period of
20 s with the tool switched “off”, the “off” periods being included in the specified operating
time.
During the tests above, the tool is placed in three different positions, the operating time, at
each test voltage, being approximately 4 h for each position.
After this, the impact wrenches are operated intermittently for 12 h at a supply voltage equal
to 1,1 times rated voltage, then for 12 h at a supply voltage equal to 0,9 times rated voltage.
Each cycle of operation comprises a tool impacting for a period of 1 s and a resting period of
9 s with the tool switched “off”, the “off” periods being included in the specified operating time.
During this test, replacement of the carbon brushes is allowed, and the tool is oiled and
greased as in normal use.
If the impact mechanism fails mechanically during the test without causing an accessible part
to become live it may be replaced by a new one.
If the temperature rise of any part of the tool exceeds the temperature rise determined during
the test of 12.1, forced cooling or rest periods are applied, the rest periods being excluded
from the specified operating time.
During these tests, overload protection devices shall not operate.
18 Abnormal operation
This clause of Part 1 is applicable.
19 Mechanical hazards
This clause of Part 1 is applicable.

with a momentary switch with no provision for being locked in the “on” position.
Compliance is checked by inspection.
24 Supply connection and external flexible cords
This clause of Part 1 is applicable, except as follows:
24.4 Replacement of paragraphs 1 and 2:
For impact wrenches, the lightest cable which can be used is:
– heavy polychloroprene sheathed flexible cable (60245 IEC 66) or equivalent.
25 Terminals for external conductors
This clause of Part 1 is applicable.
26 Provision for earthing
This clause of Part 1 is applicable.
