IEC 60079-0:1983 ED2

Electrical apparatus for explosive gas atmospheres. Part 0: General requirements IEC 60079-0:1983 ED2

Publication date:   Jan 1, 1983

Scope

Specifies general requirements for construction, testing and
marking of electrical apparatus for explosive gas atmospheres.
Applies to electrical apparatus where atmospheric conditions for
the explosion characteristics of the explosive gas atmosphere are
considered as having pressures in the range 80 kPa (0.8 bar) to 110
kPa (1.1 bar) at a temperature in the range -20°C to +60°C.
Atmospheric conditions outside this range may need special
consideration.
Does not apply to devices whose stated electrical parameters do not
exceed any of the values 1-2 V, 0.1 A, 20 µJ or 25 mW, which need
not be certified or marked as required by IEC 79. However, such
devices are subject to the requirements of the various parts of IEC
79 if they are connected to a device which contains a source or a
storage element of electrical energy which could cause the circuit
to exceed these parameters.

Supersedes IEC 79-8 and 79-9.
