IEC 60079-35-2:2011

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

IEC 60079-35-2:2011 details those performance and other safety features of caplights, including those with a point of connection for another equipment, not covered in IEC 60079-35-1, but which are important for the safety and working conditions of the user. It may also be applied to caplights for use in mines not likely to be endangered by firedamp. 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.

Atmosphères explosives - Partie 35-2: Lampes chapeaux utilisables dans les mines grisouteuses - Performances et autres sujets relatifs à la sécurité

La CEI 60079-35-2:2011 détaille les performances et les autres caractéristiques de sécurité des lampes-chapeaux, y compris de celles ayant un point de connexion pour un autre appareil, qui ne sont pas couvertes par la CEI 60079-35-1, mais qui sont importantes pour la sécurité et les conditions de travail de l'utilisateur. Elle peut aussi s'appliquer aux lampes-chapeaux utilisées dans les mines non grisouteuses. La présente première édition de la CEI 60079-35-2 annule et remplace la deuxième édition (2005) de la CEI 62013-2 publiée en 2005 dont elle constitue une révision technique complète. La révision générale et la mise à jour de l'édition 2 de la CEI 62013-2 sont devenues indispensables avec l'avènement des nouvelles technologies touchant la conception des lampes chapeaux, en particulier celles liées aux sources de lumière à diodes électroluminescentes (LED). Il est prévu de lier plus fortement la Partie 1 (Construction) et la Partie 2 (Performance) de la présente norme en modifiant le contenu du domaine d'application de la partie 1 de note en exigence. En outre, la présente norme ayant été intégrée à la série CEI 60079, des modifications ont été apportées dans un souci de plus grande cohérence avec les autres parties de la série par l'ajout de références croisées. Ceci a permis une réduction à la fois du nombre et de la longueur des articles de la présente norme.

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.

The text of this standard is based on the following documents:
FDIS Report on voting
31/955/FDIS 31/963/RVD

voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all the parts in the IEC 60079 series, under the general title Explosive atmospheres,
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
