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. IEC 79 classification of hazardous area zones. Zone classification: Zone 2: At end of definition insert: Note: The words 'places' and 'areas' are synonymous. Type 'n' equipment: Delete I.S./EN 50021. The factors relevant to the classifications of a hazardous area are the nature of the gases or dust present in the potentially explosive atmosphere. 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. Table 1 shows the IEC 79-10 zone classification used in Europe and most other parts of the world. 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).
