Circuit Integrity Fire Conditions Apparatus

Description:

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 ℃, and the continue flaming time is 90min, B grade flame temperature is 750 ~ 800 ℃, 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
