The series of UL94 Vertical Flame Chambers are based on UL94, GB2408-2008, GB/T5169-14 (IEC60695-11-2) "1KW Nominal Premixed Flame Equipment, Confirmation Test Methods and Guidelines", IEC60695-11-3 (5VA, 5VB grade material, flame power: 500W), IEC60695-11-4 (V-1 grade material, flame power: 50W), GB/T5169-16 (IEC60695-11-10) "50W flame test method", GB/T5169-17 (IEC60695-11-20) "500W flame test method", GB5169.15, GB11020, and other standards are designed and manufactured to simulate the influence of the early stage flame when a fire occurs around electrical and electronic products. In order to assess the degree of fire hazard by means of simulation techniques. It is mainly used to conduct horizontal and vertical flammability tests on the relative combustion characteristics of plastic and other non-metallic material parts samples, solid materials and foamed plastics with an apparent density of not less than 250kg/m' when measured according to the ISO845 method.
