Flame-retardant Cables: ibec60332-3 / bs4066-3 flame-retardant grades (BunchedWires or Cables vertical Flame On BunchedWires/Cables) this is a beam cable. According to the test regulations, the 3.5m long cable samples are fixed with iron wire on the trapezoid frame, and the number of samples is determined according to the non-metallic materials required for different classification. The sample is hung vertically on the back wall of the furnace and air is introduced into the furnace through the inlet on the bottom plate. At 750 ℃ flame propane plane and the sample, the sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on its own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.
