Hard to catch fire and having the ability to prevent or delay the spread of flame wire and cable can generally refers to GB/T18380.3 (equivalent to IEC60332-3) test; TESTECH wire and cable fire-resistant impact tester in accordance with IEC 60331-12 BS6387 -2013 standard. It is used to test if the circuit will maintain integrity under flame temperature is not lower than 830℃, and the case of a certain impact vibration. You can test cables A, B, C, D retardant properties.
