Foreword
The text of ISO/IEC 80079-34:2011 has been prepared by Technical Committee IEC TC 31 “Equipment for
explosive atmospheres” of the International Electrotechnical Commission (IEC) and has been taken over as
EN ISO/IEC 80079-34:2011 by Technical Committee CEN/TC 305 “Potentially explosive atmospheres –
Explosion prevention and protection” the secretariat of which is held by DIN. The enquiry took place at
ISO/CEN level (31M/31/CDV, CEN Project = WI 00305114). However, the vote on 31M/45/FDIS took place
at IEC/CLC level (agreement between ISO and IEC, see also D130/103), under the responsibility of the
Technical Committee CENELEC TC 31 “Electrical apparatus for potentially explosive atmospheres”.
The text of document 31M/45/FDIS, future edition 1 of ISO/IEC 80079-34:2010, prepared by Technical
Committee IEC TC 31 “Equipment for explosive atmospheres”, was submitted to the IEC-CENELEC parallel
vote.
A draft amendment, prepared by the Technical Committee CEN TC 305 “Electrical Potentially explosive
atmospheres – Explosion prevention and protection ", was submitted to the CENELEC formal vote.
The combined texts were approved by CEN and CENELEC as EN ISO/IEC 80079-34 on 2011-05-25.
This document supersedes EN 13980:2002.
The significant changes with respect to EN 13980:2002 are the following:
references have been changed, especially references to CEN/CENELEC and their publications have
been changed to references to international available publications;
foreword and scope have been adapted to international requirements;
terminology has been changed and adapted to terminology being more customary in the international
standardization (e. g. "notified body" has been modified to "body responsible for verification");
information relevant to particular types of protection has been amended with
Ex t - dust ignition protection by enclosure,
gas detectors and
flame arresters;
Annex B has been renamed as "Verification criteria for elements with non-measurable paths used as an
integral part of a type of protection";
B.3 has been modified;
information relevant to equipment and protective systems according to standards harmonized under
Directive 94/9/EC are given in new Annex ZB.
This standard should be read in conjunction with EN ISO 9001:2008.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an harmonized
national standard or by endorsement (dop) 2012-05-25
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2014-05-25

Annex ZB
(informative)
Information relevant to equipment and protective systems

ZB.1 Introduction
This annex provides information on those aspects that the quality system should address with respect to
particular protection laid down in harmonized standards under Directive 94/9/EC, e.g. types of protection for
non-electrical equipment or components, equipment according to specific product standards and
autonomous protective systems. It does not add to or otherwise change the requirements of this standard.
This annex provides information how to meet the requirements of this standard, recognizing that other
methods achieving the same objectives are equally acceptable; it also draws attention to aspects of
requirements that may not be readily apparent to those unfamiliar with quality systems for products intended
for use in potentially explosive atmospheres.
The examples can be used by manufacturers to check whether the safety-relevant aspects are considered in
the quality system and covered by adequate procedures (see 7.1). They can also be used for internal or
external quality audits (see 8.2).
NOTE The following examples do not cover all protection concepts but give some advice and will be supplemented
to in the next edition.
