    Abstract - (Show below) - (Hide below)

    Applies to electrical apparatus protected by encapsulation type of protection mD and surface temperature limitation for use in areas where combustible dust may be present in quantities which could lead to a fire or explosion hazard.

    Scope - (Show below) - (Hide below)

    Applicable to electrical apparatus protected by encapsulation type of protection \'mD\' and surface temperature limitation for use in areas where combustible dust may be present in quantities which could lead to a fire or explosion hazard. Specifies requirements for design, construction and testing of electrical apparatus, parts of electrical apparatus and Ex components where the rated voltage does not exceed 10 kV. The application of electrical apparatus in atmospheres which may contain explosive gas as well as combustible dust, whether simultaneously or separately, requires additional protective measures.
