Part 2-1: Particular requirements for drills and impact drills
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.

17 Endurance
This clause of Part 1 is applicable, except as follows:
17.2 Replacement for impact drills:
Impact drills are operated with no load and, if the impact mechanism can be engaged and
disengaged at will, the impact mechanism shall remain disengaged, for 12 h at 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 speed is adjusted to the highest value of the highest range.
Each cycle of operation comprises an “on” period of 100 s and an “off” period of 20 s, the off
periods being included in the specified operating time.
During the test, the tool is placed in three different positions, the operating time, at each
voltage, being approximately 4 h for each position.
During this test, replacement of the carbon brushes is allowed, and the tool is oiled and
greased as in normal use.
The tool may be switched on and off by means of a switch other than that incorporated in the tool.
The impact drills are then mounted vertically in a test apparatus as shown in Figure 101 and
are operated at rated voltage or at the mean value of the rated voltage range, for four periods
of 6 h each, the interval between these periods being at least 30 min; if the impact mechanism
can be engaged and disengaged at will, the impact mechanism shall remain engaged.
During these tests, the impact drills are operated intermittently, each cycle comprising a period
of operation of 30 s and a rest period of 90 s during which the tool remains switched off.
During the tests, an axial force, just enough to ensure steady operation of the impact
mechanism, is applied to the impact drill through a resilient medium.

60745-2-1 © IEC:2003+A1:2008 – 7 –
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.
During these tests, overload protection devices shall not operate.
NOTE 1 Monitoring of external temperatures will help avoid mechanical failures.
NOTE 2 The change of position is made to prevent abnormal accumulation of carbon dust in any particular place.
Examples of the three positions are horizontal, vertically up and vertically down.
18 Abnormal operation
This clause of Part 1 is applicable.
19 Mechanical hazards
This clause of Part 1 is applicable, except as follows:
19.1 Addition:
Chuck keys shall be so designed that they drop easily out of position when released. This
requirement does not exclude the provision of clips for holding the key in place when not in
use; metal clips fixed to the flexible cable or cord are not allowed.
Compliance is checked by inspection and manual test.
The key is inserted in the chuck and, without tightening, the tool is turned such that the key is
facing down. The key shall fall out.
19.101 The force on the hand due to static stalling torque shall not be excessive.
Compliance is checked by the following test.
Static stalling torque or slip torque of a clutch is measured on the locked output spindle of the
tool in the cold condition (M ).
R
The tool is connected to rated voltage. The mechanical gears are adjusted to the lowest speed.
Electronic regulators are adjusted to their maximum speed setting. The tool switch is to be in
the full “on” position. The mean value of the torque measured shall not exceed the relevant
maximum value in Figure 102 and Figure 103.
