1 Scope<\/b><\/p>\n
This <\/p>\n
part of IEC 60079<\/p>\n
standard<\/p>\n
contains the specific requirements for construction and assessment of intrinsically safe electrical systems, type of protection \u201ci\u201d, intended for use, as a whole or in part, <\/p>\n
in Class I, Zone 0, 1, or 2, or Zone 20, 21, or 22 hazardous (classified) locations as defined by the National Electrical Code\u00ae (NEC), ANSI\/NFPA 70\u00ae<\/p>\n
in locations in which the use of Group I, II or III apparatus is required<\/p>\n
.<\/p>\n
NOTE 1 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\u2019s staff.<\/p>\n
This standard supplements and modifies the general requirements of <\/p>\n
ANSI\/ISA-60079-0 and ANSI\/ISA-61241-0<\/p>\n
IEC 60079-0<\/p>\n
and the intrinsic safety standard <\/p>\n
ANSI\/ISA-60079-11 and ANSI\/ISA-61241-11<\/p>\n
IEC 60079-11<\/p>\n
. Where a requirement of this standard conflicts with a requirement of <\/p>\n
ANSI\/ISA-60079-0, ANSI\/ISA-60079-11, ANSI\/ISA-61241-0<\/p>\n
IEC 60079-0<\/p>\n
or <\/p>\n
ANSI\/ISA-61241-11<\/p>\n
IEC 60079-11<\/p>\n
, the requirement of this standard takes precedence.<\/p>\n<\/p>\n
This standard supplements IEC 60079-11, the requirements of which apply to electrical apparatus used in intrinsically safe electrical systems.<\/p>\n<\/p>\n
The installation requirements of Group II or Group III systems designed in accordance with this standard are specified in the <\/p>\n
National Electrical Code ANSI\/NFPA 70<\/p>\n
IEC 60079-14<\/p>\n
.<\/p>\n<\/p>\n
