Explosive atmospheres -- Part 25: Intrinsically safe electrical systems
IEC 60079-25:2010 contains the specific requirements for construction and assessment of intrinsically safe electrical systems, type of protection 'i', intended for use, as a whole or in part, in locations in which the use of Group I, II or III apparatus is required. This standard supplements and modifies the general requirements of IEC 60079-0 and the intrinsic safety standard IEC 60079-11. Where a requirement of this standard conflicts with a requirement of IEC 60079-0 or IEC 60079-11, the requirement of this standard takes precedence. This standard supplements IEC 60079-11, the requirements of which apply to electrical apparatus used in intrinsically safe electrical systems. The installation requirements of Group II or Group III systems designed in accordance with this standard are specified in IEC 60079-14. The significant changes with respect to the previous edition are: - extension of the scope from Group II to Groups I, II and III; - introduction of level of protection 'ic'; - addition of requirements for cables and multi-core cables; - reference to IEC 60079-11 rega
