scope:

This part of IEC 60079 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. NOTE This standard is intended for use by the designer of the system who may be a manufacturer, a specialist consultant or a member of the end-user's staff. 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 shall take precedence. NOTE Group I installation requirements are presently not provided in IEC 60079-14. Group III requirements will be provided in a future edition of IEC 60079-14.
