Vertical and horizontal combustion tester

The UL94 Vertical and Horizontal Flammability Tester is primarily used to assess the flammability of materials classified as V-0, V-1, V-2, HB, and 5V. It is applicable to various electrical and electronic products, including lighting equipment, electronic wires, low-voltage electrical appliances, household appliances, machine tools, electrical connectors and accessories, motors, power tools, electronic instruments, and electrical instruments. This testing equipment is also suitable for the insulation materials, engineering plastics, and other industries dealing with solid combustible materials. It can be used to conduct flammability tests on wire and cable insulating materials, printed circuit board materials, IC insulators, and other organic materials. The test involves placing the specimen on top of the fire, burning it for 15 seconds, extinguishing it for 15 seconds, and then examining the extent of incineration after repeating the test.
