Flame-retardant Cables: ibec60332-3 / bs4066-3 flame-retardantgrades (BunchedWires or Cables vertical Flame OnBunchedWires/Cables) this is a beam cable. According to the testregulations, the 3.5m long cable samples are fixed with iron wireon the trapezoid frame, and the number of samples is determinedaccording to the non-metallic materials required for differentclassification. The sample is hung vertically on the back wall ofthe furnace and air is introduced into the furnace through theinlet on the bottom plate. At 750 ℃ flame propane plane and thesample, the sample in the compulsory blowing (5 m3 / min airemissions, wind speed 0.9 m/s), must be in vertical combustion isnot up to 20 minutes, cable within 2.5 meters flame spread out onits own. IEC60332 is divided into A, B, C and D to evaluate theflame retardant performance.
