This European Standard was approved by CENELEC on 2009-06-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Cyprus, the
Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain,
Sweden, Switzerland and the United Kingdom.

Foreword
The text of document 31/708/FDIS, future edition 5 of IEC 60079-0, prepared by IEC TC 31, Equipment
for explosive atmospheres, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60079-0 on 2009-06-01.
This European Standard supersedes EN 60079-0:2006 and EN 61241-0:2006.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2010-03-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2012-06-01
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission to provide a means of conforming to Essential Requirements of the New Approach Directive
94/9/EC, for electrical equipment of Equipment Groups I and II, Equipment Categories M1, M2, 1G, 2G,
3G, 1D, 2D and 3D. See Annex ZZ.
CENELEC/TC 31 as the responsible committee has concluded that this new edition of EN 60079-0 does
not contain substantial changes regarding the ESRs.
Annexes ZA, ZY and ZZ have been added by CENELEC.
EN 60079-0 will be supplemented by standards EN 60079-X for specific types of protection and by
standards for specific products. In all cases requirements given in these standards result from an ignition
hazard assessment made on the electrical equipment. The ignition sources taken into account are those
found associated with this type of equipment, such as hot surfaces, mechanically generated sparks,
thermite reactions, electrical arcing and static electric discharge.
