Part 14 Installation (and selection) of equipment in hazardous areas. IEC 60079-10-Electrical apparatus for explosive gas atmospheres-Part 10-Classification. The British Standard BS 5345 Part 2 will become obsolete and replaced by BS/EN/IEC 60079-10. Request sharing the following standard IEC Ex 60079-19 Explosive atmospheres -Part 19: Equipment repair, overhaul and reclamation OR BS EN 60079-19 : Explosive atmospheres. IEC 60079- ELECTRICAL APPARATUS FOR EXPLOSIVE GAS ATMOSPHERES Part 3 Ed. IEC 60079-10-Electrical apparatus for explosive gas atmospheres-Part 10-Classification of hazardous areas. IEC 60079- ELECTRICAL APPARATUS FOR EXPLOSIVE GAS ATMOSPHERES. Part 10 Classification of hazardous areas. 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). 2 BS 970 Part 1: 1996 Wrought Steels for Mechanical and Allied Engineering Purposes 3 BS 2594: 1975 . Table 1 - IEC 79 classification of hazardous area zones. 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. Part 27 Fieldbus intrinsically safe concept (FISCO) Standards for Installation etc. The factors relevant to the classifications of a hazardous area are the nature of the gases or dust present in the potentially explosive atmosphere. 1.0/1963 Spark test apparatus for intrinsically safe circuits (Withdrawn) Part 10 Ed. 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. IntroductionWhen electrical equipment is used in locations where fire or explosion hazards may exist due to flammable gases or vapors, flammable liquids, combustible dust, or ignitible fibers or flyings, the Introduction When electrical These requirements apply to apparatus or parts of apparatus for installation and use in Class I, II, or III, Division 1 hazardous (classified) locations in accordance with the requirements of the National Electrical Code, NFPA 70. IEC 79 classification of hazardous area zones. Table 1 shows the IEC 79-10 zone classification used in Europe and most other parts of the world.
