  • This part of IEC 60079 contains the specific requirements forconstruction and assessment of intrinsically safe electricalsystems, type of protection "i", intended for use, as a whole or inpart, in locations in which the use of Group I, II or III apparatusis required.

    NOTE 1 This standard is intended for use by the designer of thesystem who may be a manufacturer, a specialist consultant or amember of the end-user's staff.

    This standard supplements and modifies the general requirementsof IEC 60079-0 and the intrinsic safety standard IEC 60079-11.Where a requirement of this standard conflicts with a requirementof IEC 60079-0 or IEC 60079-11, the requirement of this standardtakes precedence.

    This standard supplements IEC 60079-11, the requirements ofwhich apply to electrical apparatus used in intrinsically safeelectrical systems.

    The installation requirements of Group II or Group III systemsdesigned in accordance with this standard are specified in IEC60079-14.

    NOTE 2 Group I installation requirements are presently notprovided in IEC 60079-14.
