Execution Standards：
This tester is Designed in accordance with the corresponding provisions of UL1581-2006 section 1080 (VW-1 burning test), 1100 sections (horizontal sample / FT2 burning test).
Main function:
The UL1581 combustion chamber is suitable for testing the flame retardant properties of the insulation layer of wires and cables under abnormal conditions such as overheating and overcurrent. The laboratory consists of a test section and a control section. The control system has a high degree of automation. It has the functions of automatic ignition and temperature control, digital display of temperature and time, convenient observation and recording, and stable and reliable use.
Technical Parameters:
1.High anti-corrosion steel plate seal, spray high anti-corrosive paint, no air circulation during test
2.The front of the box is provided with a toughened glass observation door to facilitate the observation of the test
3.The operation panel is located on the right side of the observation door to facilitate observation of the test situation
