Fire Testing Equipment UL1581 Sect 1080.1~1080.14 Large Combustion Cabinet / Carge Combustion Box

Large Combustion Cabinet / Carge Combustion Box

Uses

Large combustion cabinet / large combustion chamber is strictly in accordance with UL1581 sect 1080.1~1080.14 standard, and fully comply with VW-1 (V-ertical-specimen) Flame Test. Economically applicable and widely used by the wire and cable industry
Experimental principle: The parameters of the large combustion cabinet/large combustion chamber are as follows: The whole test is carried out in a laboratory with a volume of 4.32 cubic meters. Test method: adjust the flame height, place the top of the flame under the test piece, burn for 15 seconds, extinguish for 15 seconds, repeat the test after 5 times and check the burning of the test piece, set the burning time, the extinguishing time and the number of repetitions, and automatically operating.

What are the different types of fire testing?
Fire testing – such as reaction and resistance to fire testing of materials and structures, and the performance testing of fire suppression components and systems (eg extinguishers and sprinklers), of detection and alarm systems and cables, and of smoke and heat ventilation systems.
