– 2 – 60745-2-1 Amend. 1 © IEC:2008
FOREWORD
This amendment 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.
The text of this amendment is based on the following documents:
FDIS Report on voting
61F/731/FDIS 61F/751/RVD
Full information on the voting for the approval of this amendment can be found in the report on
voting indicated in the above table.
With this amendment, this Part 2 is established on the basis of the fourth edition (2006) of
IEC 60745-1, Hand-held motor-operated electric tools – Safety – Part 1: General requirements.
Main changes include editorial modifications to match with the fourth edition of IEC 60745-1
and the addition of a new safety warning to Clause 8: Marking and instructions.
The committee has decided that the contents of this amendment and the base publication will
remain unchanged until the maintenance result date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
_____________
1 Scope
Replace the existing text of Clause 1 by the following:
This clause of Part 1 is applicable, except as follows:
Addition:
This standard applies to drills and impact drills.
3 Definitions
Change the title of Clause 3 to read:
3 Terms and definitions
8 Marking and instructions
Replace the existing text of 8.12.1 by the following:

60745-2-1 Amend. 1 © IEC:2008 – 3 –
8.12.1.1 Addition:
Drill safety warnings
− Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
NOTE The above warning applies only to impact drills and may be omitted for drills other than impact drills.
− Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal
injury.
− Hold power tool by insulated gripping surfaces, when performing an operation where
the cutting accessory may contact hidden wiring or its own cord. Cutting accessory
contacting a "live" wire may make exposed metal parts of the power tool "live" and could
give the operator an electric shock.
12 Heating
Replace the existing text of 12.3 by the following:
12.3 Addition:
The temperature-rise limit specified for the external enclosure does not apply to the enclosure
of the impact mechanism.
17 Endurance
Replace the existing text of 17.2 by the following:
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.

– 4 – 60745-2-1 Amend. 1 © IEC:2008
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.
21 Construction
Replace the existing text of 21.18 by the following:
21.18 Addition:
A switch lock-on device, if any, shall be located outside the grasping area, or so designed that
it is not likely to be unintentionally locked on by the user’s hand during intended left- or right-
handed operation. This grasping area is considered to be the contact area between either hand
and the tool while the index finger of th
