IEC 79-10 :1995 -Electrical Apparatus for Explosive Gas Atmospheres, part 10 Classification of hazardous areas. Electrical apparatus for explosive gas atmospheres — Part 0: General requirements. IP Part 15, 1990- Area Classification Code for Petroleum Installations. IEC 60079-10-Electrical apparatus for explosive gas atmospheres-Part 10-Classification. Type 'n' equipment: Delete I.S./EN 50021. Posted by A.K.Hait on 12 July, 2007 - 10:42 pm The reason for sealing between zone-1 and Zone-2 is not only to stop an explosion from propagating between locations but also to prevent the migration of gas or vapour through the conduit. The requirements for equipment to be certified as Ex d or Ex e are set out in various Standards - IEC 60079-1 for Ex d Flameproof equipment, and IEC 60079-7 for Ex e Increased Safety equipment (and documents based on these). 3.0 b:2002, Electrical apparatus for explosive gas . 10 of IEC Standard IEC 60079-14 "Electrical apparatus for explosive gas atmospheres Part 14: Electrical installations in hazardous areas. Zone classification: Zone 2: At end of definition insert: Note: The words 'places' and 'areas' are synonymous. Zone 0 describes areas in which there is a flammable gas atmosphere present for more than 1000 hours per annum ('continuously'); Zone 1 covers areas where a flammable gas atmosphere is present intermittently for more than 10 hours pa but less . 2 BS 970 Part 1: 1996 Wrought Steels for Mechanical and Allied Engineering Purposes 3 BS 2594: 1975 .
