Lampes-chapeaux utilisables dans les mines grisouteuses - Partie 1: Règles générales - Construction ...
Specifies requirements for the construction and testing of caplights for use in mines susceptible to firedamp (Group I - electrical apparatus for explosive gas atmospheres as defined in IEC 60079-0). It deals only with the risk of caplight becoming a source of ignition. The requirements of IEC 60079-0 do not apply unless specified. Is also applicable to caplights intended for use in mines…
Applies to electrical and electrically operated indicating, recording and control instruments. Establishes dimensional interchangeability between instruments made by different manufacturers. To fulfil this requirement, a defined set of dimensions has been chosen. Using these dimensions, it should be easy to combine instruments of different sizes on the same panel making good use of the available…
