Foreword
This document (EN 61029-2-11:2012) consists of the text of IEC 61029-2-11:2001 prepared by
IEC/SC 61F (transformed into IEC TC 116 "Safety of hand-held motor-operated electric tools"), together
with the common modifications prepared by CLC/TC 116 "Safety of motor-operated electric tools".
The following dates are fixed:
(dop) 2013-09-03
• latest date by which the document has to be
implemented at national level
by publication of an identical
national standard or by endorsement
(dow) 2015-09-03
• latest date by which the national standards
conflicting with the
document have to be withdrawn
This document supersedes EN 61029-2-11:2009.
EN 61029-2-11:2012 includes the following significant technical changes with respect to
EN 61029-2-11:2009:
– introduction of 'linked action'
– rewording of some clauses;
– improvement and clarification of Clause 18.
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all
such patent rights.
This European Standard is divided into two parts:
Part 1 General requirements, which are common to most transportable motor, operated tools (for the
purpose of this European Standard referred to simply as tools) which could come within the scope
of this European Standard.
Part 2 Requirements for particular types of tool which either supplement or modify the requirements
given in Part 1 to account for the particular hazards and characteristics of these specific tools.
Compliance with the relevant clauses of Part 1 together with a relevant Part 2 of this European Standard
provides one means of conforming to the specified essential requirements of the Directive.
This European Standard follows the overall requirements of EN ISO 12100.
For noise and vibration, this European Standard covers the requirements for their measurement, the
provisions of information arising from these measurements and the provision of information about the
Personal Protective Equipment required. Specific requirements for the reduction of the risk arising from
noise and vibration through the design of the tool are not given as this reflects the current state of art.
Other requirements arising from other EU Directives can be applicable to the products

CEN has prepared standards for industrial machines, which may extend to transportable machines.
Although CEN and CENELEC have where appropriate used common solutions to provide uniform levels
of protection, persons using this European Standard should check the scope of both this and CEN
standards to ensure that a correct standard is used.
This Part 2-11 is to be used in conjunction with EN 61029-1:2009. This Part 2-11 supplements or modifies
the corresponding clauses of EN 61029-1, so as to convert it into the European Standard: “Particular
requirements for combined mitre and bench saws”.
Where a particular subclause of Part 1 is not mentioned in this Part 2-11, that subclause applies as far as
reasonable. Where this Part 2-11 states "addition" "modification" or "replacement", the relevant text of
Part 1 is to be adapted accordingly.
Clauses, subclauses, notes, tables and figures which are additional to those in Part 1 are numbered
starting from 101.
Clauses, subclauses, notes, tables and figures which are additional to those in IEC 61029-2-11 are
prefixed "Z".
NOTE In this European Standard, the following print types are used:
- requirements proper: in roman type;
- test specifications: in italic type;
- explanatory matter: in smaller roman type.
This document has been prepared under a mandate given to CENELEC by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive.
For the relationship with EU Directive 2006/42/EC, see informative Annex ZZ, which is an integral part of
this document.
Endorsement notice
The text of the International Standard IEC 61029-2-11:2001 was approved by CENELEC as a
European Standard with agreed common modifications.

2.Z101
type “A” saw
combined mitre and bench saw equipped with two tables: a mitre saw table having a fence to support the
material to be cut as the saw blade is brought down and a bench table which supports the material to be
