EN 60079-2:2007

Explosive atmospheres - Part 2: Equipment protection by pressurized enclosure "p"

This part of IEC 60079 contains the specific requirements for the construction and testing of electrical apparatus with pressurized enclosures, of type of protection 'p', intended for use in explosive gas atmospheres. It specifies requirements for pressurized enclosures containing a limited release of a flammable substance. The significant changes with respect to the previous edition is the introduction of the 'Equipment protection level concept'.

Explosionsfähige Atmosphäre - Teil 2: Geräteschutz durch Überdruckkapselung "p"

Atmosphères explosives - Partie 2: Protection du matériel par enveloppe à surpression interne "p"

La présente partie de la CEI 60079 contient les exigences spécifiques pour la construction et les essais des matériels électriques avec enveloppes à surpression interne à mode de protection 'p', destinés à l'utilisation dans les atmosphères explosives gazeuses.

Foreword
The text of document 31/668/FDIS, future edition 5 of IEC 60079-2, prepared by IEC TC 31, Equipment
for explosive atmospheres, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 60079-2 on 2007-11-01.
This European Standard supersedes EN 60079-2:2004 + corrigendum April 2006.
The significant changes with respect to EN 60079-2:2004 are listed below:
– introduction of the “Equipment protection level concept” – See Annex H;
– 3.13 eliminate reference to “room” in the definition of pressurization;
– 5.3.3 restrict to type px;
– 5.3.3 add warning for type pz and type py for any cover removable without the use of a tool;
– 7.6 move wording “For type px” to beginning of subclause to clarify 7.6 only applies to type px;
– 7.7 c) clarify that the instruction label should specify purge time and pressure/flow;
– 18.7 collect marking requirements throughout the document in the “Marking” clause.
This European Standard is to be read in conjunction with EN 60079-0:2006.
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) 2008-08-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-11-01
This European Standard was prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and supports the essential requirements of
Directive 94/9/EC. See Annex ZZ.
