    Abstract - (Show below) - (Hide below)

    Specifies design, construction and testing requirements for non-sparking electrical equipment for use in explosive atmospheres. Includes the requirements for enclosed-break devices and non-incendive components, sealed devices and restricted-breathing enclosures. Technically similar to IEC 79-15.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for the design, construction and testing of non-sparking type electrical equipment, intended for use in Class 1 Zone 2 hazardous areas.This Standard supplements AS 2380.1, except for the requirements of the following clauses which do not apply:2.1.4 Enclosed equipment2.2 Enclosures of non-metallic material2.3.2 Group II equipment2.9.3 Bonding facilities2.11.2 Conduit entry3.3 Enclosures containing fuses3.4 Plugs and socket-outlets5.2.2 Drop test5.6 Thermal shock test
