Wire and Cable Fire Resistance Tester IEC 60331
Introduction:
Fire-resistant cable refers to a cable that can keep a safe running time in the case of flame combustion.
IEC 60331 divides the fire resistance test into A, and B two classes, The flame temperature of A grade is 950 ~ 1000 ºC, and the continue flaming time is 90min, B grade flame temperature is 750 ~ 800 ºC, the flaming time is 90 min. In addition, the test specimen shall bear the rated voltage during the test. The fire Resistance Tester is designed according to the requirements of IEC60331-11 and used to obtain the refractory characteristics of a fire-resistant cable or optical cable under flame conditions.
Standards:
IEC 60331 Part 11
IEC 60331 Part 21
BS 6387(Option)
Main Features:
1. All fixtures are made of stainless steel;
2. The burner is a belt-type propane blowtorch with a Venturi mixer, and the burner nozzle is length 500mm, width 15mm;
3. Those burning holes are staggered into 3 rows, and the front width is 15mm, the holes diameter is 1.32mm and these holes center distance is 3.2mm;
