Foreword
The text of the International Standard IEC 60745-2-8:2003, prepared by SC 61F (transformed into
IEC TC 116, Safety of hand-held motor-operated electric tools), together with the common
modifications prepared by the Technical Committee CENELEC TC 61F (transformed into TC 116) was
submitted to the formal vote and was approved by CENELEC as EN 60745-2-8 on 2003-02-01.
A draft amendment (prAB) was prepared to align Subclause 6.2 with the new Subclause 6.2 in
EN 60745-1. Moreover, vibration values determined with the new 6.2 are complying with the
requirements of the Physical Agents Directive Vibration 2002/44/EC. The text of the draft was
submitted to the Unique Acceptance Procedure and was approved by CENELEC as amendment A11
to EN 60745-2-8:2003 on 2007-06-01.
The text of document 61F/735/FDIS, future amendment 1 to IEC 60745-2-8:2003, was submitted to
the IEC-CENELEC parallel vote and was approved by CENELEC as amendment A1 to
EN 60745-2-8:2003 on 2009-04-22.
A further draft amendment (prAC), extending Annex ZZ to include the new MD 2006/42/EC, was
submitted to the formal vote.
The combined texts were approved by CENELEC as a new edition of EN 60745-2-8 on 2009-07-01.
This European Standard supersedes EN 60745-2-8:2003 + A11:2007 + A1:2009.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-02-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-05-01
This standard is divided into two parts:
Part 1: General requirements which are common to most hand-held electric motor-operated tools (for
the purpose of this standard referred to simply as tools) which could come within the scope of
this standard;
Part 2: Requirements for particular types of tools which either supplement or modify the requirements
given in Part 1 to account for the particular hazards and characteristics of these specific tools.
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and supports the essential requirements of
EC Directive 98/37/EC (Machinery Directive), amended by EC Directive 98/79/EC, and of EC Directive
2006/42/EC. See Annexes ZZA and ZZB.
Compliance with the clauses of Part 1 together with this Part 2 provides one means of conforming with
the essential health and safety requirements of the Directive concerned.
CEN/TC 255 is producing standards for non-electric shears and nibblers (EN 792-11).
Warning: Other requirements and other EC Directives can be applicable to the products falling
within the scope of this standard.
This standard follows the overall requirements of EN ISO 12100-1 and EN ISO 12100-2.

Subclauses, tables and figures which are additional to those in IEC 60745-2-8 are prefixed “Z”.
NOTE In this standard, the following print types are used:
- Requirements: in roman type;
- Test specification: in italic type;
- Notes: in smaller roman type.

6.2.6.3 Operating conditions
Modification:
Table Z101 – Operating conditions for shears and nibblers
Orientation Cutting a horizontal strip of sheet metal with a minimum length of 400 mm and a
minimum width of 400 mm.
The metal sheet shall have the maximum thickness specified in 8.1 (tensile strength =
390 N/mm²).
The metal sheet used in the test shall be firmly secured to the test rig using resilient
material. It shall be mounted so that it does not have any significant resonance in the
frequency range that can influence the test result. A typical test rig is shown in
Figure Z102.
Each cut strip of 50 mm wide for the width of 400 mm shall be as near as possible to the
support.
During the test, the tool shall be arranged so that the operator can have an upright or
almost upright posture and work the nibbler or shear cutting horizontally. The operator
shall be able to hold the tool comfortably during the test.
Tool bit Nibblers are operated with a punch and die of the size specified for the sheet metal
used in the test.
Shears are operated with shear blades of the size specified for the sheet metal used in
the test.
They shall be sharp and in good condition.
Feed force Suitable feed force shall be applied to ensure a stable and smooth operation.
Test cycle Cutting off one 50 mm wide strip across the 400 mm width of the sheet metal.
The measurement starts when the blade enters the sheet metal and finishes when the
blade leaves the sheet metal.
6.2.7.2 Declaration of the vibration total value
Addition:
The vibration total value a of the handle with the highest emission and the uncertainty K shall be declared.
