1. Scope
This Standard defines the specific requirements for the design, selection and mounting of electrical installations in explosive gas atmospheres. These requirements are complementary to the requirements for electrical installations in non-hazardous areas.
This Standard applies to all electrical equipment and installations in hazardous areas whether permanent, temporary, movable, transportable or hand-held.
This Standard does not apply to:
— electrical installations under the shaft of mines;
Note： This standard may apply to electrical installations under the shaft of mines with other explosive gas other than firedamp and electrical installations on the ground of mines.
— electrical installations in areas where the hazard is due to combustible dusts or fibres;
— inherently explosive situations, for example explosive manufacturing and processing;
— room used for medical purpose.
