IEC 60079-14:1996

Gives guidance on the design, selection and erection of electrical installations in areas where explosive gas atmospheres could occur. Applies to all permanent electrical installations within the scope of IEC 364-1. However, may be applied, where appropriate, to electrical installations with voltages higher than the upper limit of IEC 364-1, namely 1 000 V a.c. Wherever possible the recommendations given should also be applied to temporary electrical installations, such as experimental prototype or pilot industrial installations. This publication has the status of a technical report.

This part of IEC 60079 contains the specific requirements for the design, selection and erection of electrical installations in explosive gas atmospheres. These requirements are in addition to the requirements for installations in non-hazardous areas. This standard applies to all electrical equipment and installations in hazardous areas whether permanent, temporary, portable, transportable or hand-held. It applies to installations at all voltages. This standard does not apply to - electrical installations in mines susceptible to firedamp; - electrical installations in areas where the hazard is due to combustible dusts or fibres; - inherently explosive situations, for example explosives manufacturing and processing; - rooms used for medical purposes.
