IEC 60331 Wire and Cable Fire-Resistant Impact Tester
Hard to catch fire and having the ability to prevent or delay the spread of flame wire and cable can generally refers to IEC60332-3 test; GOLD 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 830ºC, and the case of a certain impact vibration. You can test cables A, B, C, D retardant properties.
