ActiveTesting method and judging rule of safety to friction spark of metallic material for coal mine
煤矿用金属材料摩擦火花安全性试验方法和判定规则
Application Summary AI generated
This standard specifies the testing method and judging criteria for evaluating the safety of metallic materials used in coal mines against friction-induced sparks. It is applied to assess the fire and explosion risk when metal components, such as mining tools or machinery parts, come into contact with rock or other metals in potentially explosive coal mine atmospheres. The standard ensures that only materials meeting the spark safety requirements are used in underground coal mining operations to prevent ignitions.
