GB/T 7957-2017
AbolishedGeneral requirements for construction，performance and explosion protected testing of caplights for use in mines susceptible to firedamp
瓦斯环境用矿灯结构、性能和防爆试验通用要求
Application Summary AI generated
This standard specifies the structural, performance, and explosion-proof testing requirements for caplights used in mines where firedamp (methane) gas may be present. It is applied to the design, manufacturing, and certification of miner's cap lamps to ensure they operate safely without igniting explosive atmospheres. The standard is critical for mining safety compliance, particularly in coal mines and other underground operations with flammable gas risks.
