Publisher: IEC

1.0/1963 Spark test apparatus for intrinsically safe circuits (Withdrawn) Part 10 Ed. Explosive atmospheres — Part 1: Equipment protection by flameproof enclosures 'd' Delete I.S./EN 50018. 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). Electrical apparatus for explosive gas atmospheres — Part 0: General requirements. 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. Table 1 - IEC 79 classification of hazardous area zones. The British Standard BS 5345 Part 2 will become obsolete and replaced by BS/EN/IEC 60079-10. The increase in the use of fieldbus systems in hazardous areas was given a significant boost by the development of an international IEC standard for intrinsically safe (IS) fieldbus systems. The factors relevant to the classifications of a hazardous area are the nature of the gases or dust present in the potentially explosive atmosphere. Zone classification: Zone 2: At end of definition insert: Note: The words 'places' and 'areas' are synonymous. Table 1 shows the IEC 79-10 zone classification used in Europe and most other parts of the world.
