    Abstract - (Show below) - (Hide below)

    Specifies the design, construction and testing requirements for the flameproof enclosure of electrical equipment for use in explosive atmospheres. Technically equivalent to IEC 79-1.

    Scope - (Show below) - (Hide below)

    This Standard specifies requirements for the flameproof enclosure of electrical equipment, type of protection d, intended for use in hazardous areas.The Standard provides for the grouping of enclosures according to the dimensions of the gaps between joint surfaces, and an indication is given of the explosive gas atmosphere for which each group is appropriate. Some additional requirements may be necessary for non-metallic materials and these are left to the discretion of the testing authority (see Appendix C).This Standard does not apply to enclosures kept charged with air or other non-flammable gas so as to prevent the entry of flammable gas, or to enclosures containing hydrocarbon oil and parts of equipment into which gaseous products from the oil may enter.Electrical equipment with type of protection d shall be designed for operation within the ambient temperature range specified in AS 2380.1. For ambient temperatures below -20C, stronger enclosures may be required due to the higher explosion pressures generated at low temperatures and the possibility of brittle failure of enclosure materials. For ambient temperatures above 60C, it may be necessary to use smaller joint gaps because the maximum safe gap tends to decrease with an increase in ambient temperature.The specific requirements in this Standard are additional to the general requirements in AS 2380.1, except for Clause 2.11.2 which does not apply.
