Fire-resistant cable refers to the cable that can keep a safe running time in the case of flame combustion.
China's national standard GB12666.6 (equivalent to IEC331) divides the fire resistance test into A, B two classes, The flame temperature of A grade is 950 ~ 1000 â, and the continue flaming time is 90min, B grade flame temperature is 750 ~ 800 â, flaming time is 90 min. In addition,tthe test specimen shall bear the rated voltage during the test.
TESTECH Fire Resistance Tester is designed according to the requirements of GB/T19216.11-2003 (alternative GB12666.6) and IEC60331-11,and used to obtain the refractory characteristics of a fire resistant cable or optical cable under flame conditions.
Model:FTech-IEC60331
