Explosive atmospheres - Part 35-1: Caplights for use in mines susceptible to firedamp - General requirements - Construction and testing in relation to the risk of explosion
This part of IEC 60079-35 specifies requirements for the construction, testing and marking of caplights, including caplights with a point of connection for other equipment, for use in mines susceptible to firedamp (Group I – electrical equipment for explosive gas atmospheres as defined in IEC 60079-0:2007). It deals only with the risk of the caplight becoming a source of ignition.The requirements for performance are in IEC 60079-35-2.2This standard supplements and modifies the general requirements of IEC 60079-0:2007except as indicated in Table 1. Where a requirement of this standard conflicts with a requirement of IEC 60079-0:2007, the requirements of this
