This European Standard contains the specific requirements for the construction and testing of increased safety electrical apparatus, type of protection e, intended for use in potentially explosive atmospheres. This European Standard supplements European Standard EN 50 014 General Requirements, the requirements of which apply to increased safety electrical apparatus. This European Standard applies to electrical apparatus and parts of electrical apparatus which do not produce sparks or arcs or dangerous temperatures in normal service and which have rated voltages not exceeding 11 kV. Note: Electrical apparatus which does not produce electric sparks or arcs in normal service attains the degree of safety required for electrical apparatus of type of protection increased safety e only by the application of the specific measures prescribed in this European Standard
