Publisher: IEC




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. 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 . 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.
