AbolishedTesting 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 test method and evaluation criteria for assessing the risk of friction sparks generated by metallic materials used in coal mines. It is applied to ensure that tools, machinery components, and structural materials do not produce incendiary sparks when rubbed against rock or other metals in underground coal mining environments, where methane or coal dust explosions are a hazard. The standard is used by mining equipment manufacturers and safety regulators to certify materials as safe for use in explosive atmospheres.
