This large combustion cabinet is produced strictly in accordance with UL1581 SECT1080.1-1080.14 standards and has been approved by Guangzhou meihua UL company. It fully complies with VW-1 (V-ertical-specimen) Flame Test combustion test standards. Economical and practical, it is widely used in the wire and cable industry. The parameters are detailed as follows:
The entire experiment was conducted in a sealed laboratory with a volume of 4.32 cubic meters. Test method: Adjust the flame height properly, place the top of the flame under the specimen, burn for 15 seconds, extinguish for 15 seconds, repeat 5 times, and then check the burning condition of the specimen. The burning and extinguishing time as well as the number of repetitions can be set, and it can be operated automatically. It is applicable to VF-1 of UL1581, UL13, UL444 and UL1655, as well as FT-1 and FT-2 of CSA. I. Combustion Chamber
