1. Test standard
The test machine is designed according to the relevant provisions of UL1581-2006 1080 (VW -1 combustion test) and 1100 section (horizontal sample/FT2 combustion test).
2. Main functions
UL1581 combustion test chamber is suitable for testing the flame retardant properties of the insulation layer of the cable under abnormal conditions such as overheat and overflow. The test chamber consists of test part and control part. The control system has high degree of automation. It has automatic ignition and temperature function, temperature and time number display. It is convenient to observe and reliable.
