Describes specific requirements related to risk of gas explosion for construction and testing caplights for use in mines susceptible to firedamp (electrical apparatus for potentially explosive atmospheres of group I). These requirements are supplemented by the following requirements for caplights for mines susceptible to firedamp: -6.3 'Electrostatic charges of enclosures of plastics material' and 7.1 (permitted light alloys for enclosures) of EN 50014; -3.2 'internal connections, 3.5 'solid insulating materials' and 3.8 'Internal wiring' of EN 50019.
