This testing machine is designed according to the corresponding clauses of Section 1080 (VW-1 Burning Test) and Section 1100 (Horizontal Sample/FT2 Burning Test) of UL1581-2006.
The UL1581 combustion Test Chamber is suitable for testing the flame retardancy of the insulation layer of wires and cables under abnormal conditions such as overheating and overcurrent. The laboratory consists of a test part and a control part. The control system has a high degree of automation, with automatic ignition and temperature calibration functions, digital display of temperature and time, convenient observation and recording, and stable and reliable use.
Sealed with high anti-corrosion steel plate, sprayed with high anti-corrosion paint, no air circulation during the test
There is a toughened glass observation door on the front of the box, which is convenient for observing the test situation
The operation panel is located on the right side of the observation door, which is convenient for observing the test situation
Internal volume ≥ 4.0m3
Dimensions: 2100*1360*2200mm
Thermal sensor (electrolytic copper block 10.0±0.05g and thermocouple)
K-type thermocouple, equipped with a jacket of 0.5mm diameter stainless steel tube
The intelligent PID temperature control meter is matched with the K-type thermocouple, and its reading can reach 1000°C
Timer: 0 ~ 99H99 / 99M99 / 99S99 can be set arbitrarily, the minimum resolution can reach 0.01S
It takes 54s±2s for the test flame to rise from 100℃±2℃ to 700℃±3℃
Main Fixtures: Test Stand and Burning Blowtorch
Test bracket: made of SUS304# stainless steel, divided into horizontal bracket and vertical bracket
