Overview

IEC 60745-2-8:2003+AMD1:2008 CSV is an international standard developed by the International Electrotechnical Commission (IEC) focused on the safety requirements for hand-held motor-operated electric tools, specifically for shears and nibblers. It builds upon the general safety provisions set out in IEC 60745-1, detailing particular requirements applicable to these metal cutting and punching tools.

This standard applies to tools with rated voltage limits of up to 250 V for single-phase AC or DC, and up to 440 V for three-phase AC tools. It integrates the second edition from 2003 with Amendment 1 from 2008, providing a consolidated version that facilitates compliance without the need to order amendments separately.

Key Topics

• Scope and Application: The standard is specific to shears and nibblers designed for cutting or punching metal sheets, plates, and strips. It supplements the general safety requirements of IEC 60745-1 with tailored provisions to address the unique risks associated with these tools.

• Definitions:

  • Shear: A tool intended for shearing metal sheets, plates, and strips.
  • Nibbler: A tool designed for punching metal sheets, plates, and strips.

• Marking and Instructions: Tools must be clearly marked with the maximum thickness of metal, measured in millimeters, that can be safely cut. This marking refers to steel with a tensile strength of 390 N/mm² unless otherwise specified.

• Construction and Mechanical Safety: Special attention is given to the tool construction ensuring mechanical strength and protection against mechanical hazards. Certain clauses from the general Part 1 standard are modified or not applicable to better suit shears and nibblers.

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.
This part of International Standard IEC 60745 has been prepared by subcommittee 61F:

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 of IEC 60745-1, so as to
convert that publication into the IEC standard: Safety requirements for electric shears and
nibblers.
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;
– 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 smaller 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.
With amendment 1, 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 clarifications in Annex K.
The committee has decided that the contents of the base publication and its amendments 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.
