Annotation of standard text IEC 60079-2-ed.6.0 :
IEC 60079-2:2014 contains the specific requirements for the construction and testing of electrical equipment with pressurized enclosures, of type of protection "p", intended for use in explosive gas atmospheres or explosive dust atmospheres. It also includes the requirements for pressurized enclosures containing a limited release of a flammable substance. This standard supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this standard conflicts with a requirement of IEC 60079-0, the requirements of this standard take precedence. This standard does not include the requirements for: - pressurized enclosures where the containment system may release air with an oxygen content greater than normal, or oxygen in combination with inert gas where the oxygen is in a proportion greater than 21 %; - pressurized rooms or analyser houses; see IEC 60079-13; - pressurized enclosures used where "explosives" or pyrotechnics are present; - pressurized enclosures used where hybrid mixtures of gas/vapour and combustible dust are present; - pressurized enclosures used where pyrophoric substances such as explosives or propellants containing their own oxidizers are present; - pressurized enclosures with an internal source of release of combustible dust. This sixth edition cancels and replaces the fifth edition published in 2007. This sixth edition cancels and replaces the first edition of IEC 61241-4 published in 2001. This sixth edition constitutes a technical revision. The significance of changes between IEC 60079-2, Edition 6.0, 2014 and IEC 60079-2, Edition 5.0, 2007 are as listed in the foreword of the document. Keywords: electrical equipment with pressurized enclosures, type of protection "p", explosive gas atmospheres, explosive dust atmospheres The contents of the corrigendum of July 2015 have been included in this copy. IEC 60079-2:2014 contient les exigences specifiques pour la construction et les essais des materiels electriques avec enveloppes a surpression interne a mode de protection "p", destines a lutilisation dans les atmospheres explosives gazeuses ou les atmospheres de poussiere explosives. Elle inclut egalement les exigences pour les enveloppes a surpression interne contenant un degagement limite de substance inflammable. La presente Norme complete et modifie les exigences generales de lIEC 60079-0. Lorsquune exigence de la presente Norme entre en conflit avec une exigence de lIEC 60079-0, cest lexigence de la presente Norme qui prevaut. La presente Norme ne comprend pas les exigences pour: - les enveloppes a surpression interne lorsque le systeme de confinement peut degager de lair avec une teneur en oxygene superieure a la normale, ou un melange doxygene et de gaz inerte dans une proportion doxygene superieure a 21 %; - les salles a surpression interne ou les batiments pour analyseurs; voir lIEC 60079-13; - les enveloppes a surpression interne utilisees lorsque des "explosifs" ou des elements pyrotechniques sont presents; - les enveloppes a surpression interne utilisees lorsque des melanges hybrides de gaz/vapeur et de poussiere combustible sont presents; - les enveloppes a surpression interne utilisees lorsque des substances pyrophoriques telles que des explosifs ou des charges de poudre contenant leurs propres oxydants sont presentes; - les enveloppes a surpression interne avec une source interne de degagement de poussiere combustible. Cette sixieme edition annule et remplace la cinquieme edition parue en 2007. Cette sixieme edition annule et remplace la premiere edition de lIEC 61241-4 parue en 2001. Cette sixieme edition constitue une revision technique. Limportance des modifications entre lIEC 60079-2, Edition 6.0, 2014 et lIEC 60079-2, Edition 5.0, 2007, sont identifies dans lavant-propos du document.
