Abstract

IEC 60079-31:2019 is applicable to equipment protected by enclosure and surface temperature limitation for use in explosive dust atmospheres. It specifies requirements for design, construction and testing of Ex Equipment and Ex Components.
This document supplements and modifies the general requirements of IEC 60079-0. Where a requirement of this document conflicts with a requirement of IEC 60079-0, the requirement of this document takes precedence.
This document does not apply to dusts of explosives, which do not require atmospheric oxygen for combustion, or to pyrophoric substances.
This document does not apply to Ex Equipment or Ex Components intended for use in underground parts of mines as well as those parts of surface installations of such mines endangered by firedamp and/or combustible dust.
This document does not take account of any risk due to an emission of flammable or toxic gas from the dust.
