This European Standard specifies the requirements for the construction and testing of oil-immersed electrical apparatus, oil-immersed parts of electrical apparatus and Ex components in the type of protection 'o', intended for use in potentially explosive atmospheres of gas, vapour and mist. Potentially explosive atmospheres include the presence of combustible dusts. This European Standard covers Category 2G and Category M2 only. This European Standard supplements EN 50014, in so far that it applies to oil-immersed electrical apparatus. This European Standard is applicable to electrical apparatus and parts of electrical apparatus which are not ignition capable in normal operation. Compliance of the electrical apparatus shall be assessed against IEC 60079-15 except for those parts designed to comply with EN 50020. NOTE: This European Standard assumes that the electrical apparatus immersed in the protective liquid is fixed in its operating position in accordance with the installation instructions
