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
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
