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

NEW! IEC 60079-2:2014 is available as IEC Standards+ 60079-2:2014 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. 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 explosi ve 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

Explosionsgefährdete Bereiche - Teil 2: Geräteschutz durch Überdruckkapselung "p"

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

NEW! IEC 60079-2:2014 est disponible sous forme de IEC Standards+ 60079-2:2014 qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente. L'IEC 60079-2:2014 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 ou les atmosphères de poussière explosives. Elle inclut également les exigences pour les enveloppes à surpression interne contenant un dégagement limité de substance inflammable. La présente Norme complète et modifie les exigences générales de l'IEC 60079-0. Lorsqu'une exigence de la présente Norme entre en conflit avec une exigence de l'IEC 60079-0, c'est l'exigence de la présente Norme qui prévaut. La présente Norme ne comprend pas les exigences pour: - les enveloppes à surpression interne lorsque le système de confinement peut dégager de l'air avec une teneur en oxygène supérieure à la normale, ou un mélange d'oxygène et de gaz inerte dans une proportion d'oxygène supérieure à 21 %; - les salles à surpression interne ou les bâtiments pour analyseurs; voir l'IEC 60079-13; - les enveloppes à surpression interne utilisées lorsque des "explosifs" ou des éléments pyrotechniques sont présents; - les enveloppes à surpression interne utilisées lorsque des mélanges hybrides de gaz/vapeur et de poussière combustible sont présents; - les enveloppes à surpression interne utilisées lorsque des substances pyrophoriques telles que des explosifs ou des charges de poudre contenant leurs propres oxydants sont présentes; - les enveloppes à surpression interne avec une source interne de dégagement de poussière combustible. Cette sixième édition annule et remplace la cinquième édition parue en 2007. Cette sixième édition annule et remplace la première édition de l'IEC 61241-4 parue en 2001. Cette sixième édition constitue une révision technique. L'importance des modifications entre l'IEC 60079-2, Édition 6.0, 2014 et l'IEC 60079-2, Édition 5.0, 2007, sont identifiés dans l'avant-propos du document. Mots clés: matériels électriques avec enveloppes à surpression interne, mode de protection "p", atmosphères explosives gazeuses, atmosphères de poussière explosives

Eksplozivne atmosfere - 2. del: Zaščita opreme z nadtlakom "p" (IEC 60079-2:2014)

Ta del standarda IEC 60079 vsebuje specifične zahteve za konstrukcijo in preskušanje električne opreme, zaščitene z nadtlakom »p«, ki je namenjena za uporabo v eksplozivnih plinskih atmosferah ali eksplozivnih prašnih atmosferah. Vključuje tudi zahteve za ohišja v nadtlaku z omejenim sproščanjem vnetljivih snovi.
Ta standard dopolnjuje in spreminja splošne zahteve standarda IEC 60079-0. Kadar je zahteva iz tega standarda v nasprotju z zahtevo iz standarda IEC 60079-0, ima prednost zahteva iz tega standarda.
Ta standard ne določa zahtev za:
• ohišja v nadtlaku, pri katerih zadrževalni sistem lahko sprosti
a) zrak z vsebnostjo kisika, višjo od običajne, ali
b) kisik v kombinaciji z inertnim plinom, pri čemer je vsebnost kisika višja od 21 %.
• zaprte prostore z nadtlakom ali prostore za analiziranje; glej standard IEC 60079-13;
• ohišja v nadtlaku, ki se uporabljajo ob prisotnosti »eksplozivov« ali pirotehnike;
• ohišja v nadtlaku, ki se uporabljajo ob prisotnosti hibridnih mešanic plina/hlapov in gorljivega prahu;
• ohišja v nadtlaku, ki se uporabljajo ob prisotnosti pirofornih snovi, kot so eksplozivi ali pogonska goriva, ki vsebujejo svoje oksidante;
• ohišja v nadtlaku, ki vsebujejo notranji vir sproščanja gorljivega prahu.
OPOMBA Ko je uporabnik v vlogi izdelovalca, je običajno uporabnik odgovoren, da zagotovi uveljavitev vseh ustreznih delov tega standarda pri izdelavi in preskušanju opreme.
