Foreword
The text of document 31/955/FDIS, future edition 1 of IEC 60079-35-2, prepared by IEC/TC 31
"Equipment for explosive atmospheres" was submitted to the IEC-CENELEC parallel vote and approved
by CENELEC as EN 60079-35-2:2012.

The following dates are fixed:
(dop) 2013-02-10
• latest date by which the document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2015-01-11

standards conflicting with the
document have to be withdrawn

This document supersedes EN 62013-2:2006.
The general revision and updating of EN 62013-2:2006 has been necessitated by the advent of new
technologies related to caplight design, in particular those related light-emitting diode (LED) light sources.
It is intended that there should be a stronger link between Part 1 (Construction) and Part 2 (Performance)
of this standard by upgrading the reference in the scope of part 1 from a note to a requirement.
In addition, as this standard is now to become one of the EN 60079 series, changes have been made to
bring it more in line with others in the series by cross referencing. This has enabled there to be a
reduction in the number and length of clauses in the standard.
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.

Endorsement notice
The text of the International Standard IEC 60079-35-2:2011 was approved by CENELEC as a European
Standard without any modification.

Part 35-2: Caplights for use in mines susceptible to firedamp –
Performance and other safety-related matters

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 60079-35-2 has been prepared by IEC technical committee 31:
Equipment for explosive atmospheres.
This first edition of IEC 60079-35-2 cancels and replaces the second edition (2005) of
IEC 62013-2 published in 2005 and constitutes a full technical revision.
The general revision and updating of Edition 2 of IEC 62013-2 has been necessitated by the
advent of new technologies related to caplight design, in particular those related light-emitting
diode (LED) light sources. It is intended that there should be a stronger link between Part 1
(Construction) and Part 2 (Performance) of this Standard by upgrading the reference in the
Scope of part 1 from a note to a requirement.
In addition as this Standard is now to become one of the IEC 60079 series, changes have
been made to bring it more in line with others in the series by cross referencing. This has
enabled there to be a reduction in the number and length of clauses in the Standard.
