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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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 60745-2-23 has been prepared IEC technical committee 116:

Safety of motor-operated electric tools.
The text of this standard is based on the following documents:
FDIS Report on voting
116/111/FDIS 116/120/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

This part 2 is to be used in conjunction with the latest edition of IEC 60745-1 and its

amendments. It was established on the basis of the fourth edition (2006) of that standard.

NOTE 1 When “Part 1” is mentioned in this standard, it refers to IEC 60745-1.

This part 2 supplements or modifies the corresponding clauses in IEC 60745-1, so as to

convert that publication into the IEC standard: Safety requirements for die grinders and small

rotary tools.

When a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies

as far as is reasonable. When this standard states “addition”, “modification” or “replacement”,

the relevant text in Part 1 is to be adapted accordingly.
NOTE 2 The following numbering system is used:

– subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1;

– unless notes are in a new subclause or involve notes in Part 1, they are numbered starting from 101, including

those in a replaced clause or subclause;
– additional annexes are lettered AA, BB, etc.
NOTE 3 In this standard, the following print types are used:
– requirements: in roman type;
– test specifications: in italic type;
– notes: in small roman type.

Words in bold in the text are defined in Clause 3. When a definition concerns an adjective, the adjective and the

associated noun are also in bold.

A list of all parts of the IEC 60745 series, under the general title: Hand-held motor-operated

electric tools – Safety, can be found on the IEC website.

The committee has decided that the contents of this publication will remain unchanged until

the stability 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.

n……………………….rated speed
8.12.1 Addition:

For the following safety instructions specified in 8.12.1.101 to 8.12.1.104, the terms such as

grinding/grinder, sanding/sander, wire brushing/wire brush, polishing/polisher, carving/carving

tool or cutting-off/cut-off tool, are selected as recommended by the manufacturer. These

terms in the warnings and headings shall be consistently used or deleted based on the

selected operations. The “and”/“or” conjunctions may be used as appropriate.

If the power tool is recommended only for one of the listed operations, the heading of that

section is to be used for all warnings.
8.12.1.101 Safety instructions for all operations

Safety warnings common for grinding, sanding, wire brushing, polishing, carving or

abrasive cutting-off operations:
NOTE In the above heading those operations not applicable are omitted.

a) This power tool is intended to function as a grinder, sander, wire brush, polisher,

carving or cut-off tool. Read all safety warnings, instructions, illustrations and

specifications provided with this power tool. Failure to follow all instructions listed

below may result in electric shock, fire and/or serious injury.
NOTE List only those operations that are applicable.

b) Operations such as grinding, sanding, wire brushing, polishing or cutting-off are

not recommended to be performed with this power tool. Operations for which the
power tool was not designed may create a hazard and cause personal injury.

NOTE List only those operations that were not included in the first warning. If all listed operations are

applicable, then this warning is omitted, but all subsequent warnings are given without exclusion.

c) Do not use accessories which are not specifically designed and recommended by

the tool manufacturer. Just because the accessory can be attached to your power tool, it

does not assure safe operation.

d) The rated speed of the grinding accessories must be at least equal to the maximum

speed marked on the power tool. Grinding accessories running faster than their rated

speed can break and fly apart.
e) The outside diameter and the thickness of your accessory must be within the

capacity rating of your power tool. Incorrectly sized accessories cannot be adequately

controlled.

f) The arbour size of wheels, sanding drums or any other accessory must properly fit

the spindle or collet of the power tool. Accessories that do not match the mounting

hardware of the power tool will run out of balance, vibrate excessively and may cause loss

of control.
