Scope

This European Standard is applicable to electrical apparatus protected by enclosure and temperature limitation for use in areas where combustible dust may be present in quantities which could lead to a fire or explosion hazard. This standard gives guidance on the selection, installation and maintenance of electrical apparatus. NOTE: EN 50281-1-1 specifies requirements for the design, construction and testing of electrical apparatus. The ignition protection is based on the limitation of the maximum surface temperature of the enclosure and on the restriction of dust ingress into the enclosure by the use of dust-tight or dust-protected enclosures. The application of electrical apparatus in atmospheres that may contain explosive gas as well as combustible dust, whether simultaneously or separately, requires additional protection measures. The principles of this standard can also be followed when combustible fibres or flyings cause a hazard. This standard does not apply to dusts of explosives which do not require atmospheric oxygen for combustion, or to pyrophoric substances. This Standard is not applicable to electrical apparatus for use in mines susceptible to firedamp; nor does it take account of any risk because of an emission of flammable or toxic gas from the dust. This standard does not include other types of protection and is only applicable to protection by enclosure and temperature limitation
