Electrical apparatus for explosive gas atmospheres - Part 1: Flameproof enclosures 'd'
Executive summaryRequirements for the construction and testing of electrical apparatus with protection flameproof enclosure ‘d’.
AbstractThis part of EN 60079 contains specific requirements for the construction and testing of electrical apparatus with the type of protection flameproof enclosure ‘d’, intended for use in explosive gas atmospheres.
This European Standard covers supplementary requirements for shafts and bearings, breathing and draining devices which form part of flameproof enclosures, fasteners, associated holes and closing devices, materials and mechanical strength of enclosures, verification and tests, and non-metallic enclosures and non-metallic parts of enclosures.
