Vertical and horizontal combustion tester

Short Description:

The vertical and horizontal combustion test primarily refers to standards such as UL 94-2006, IEC 60695-11-4, IEC 60695-11-3, GB/T5169-2008, and others. These standards involve using a specified size Bunsen burner and a specific gas source (methane or propane) to ignite the specimen multiple times at a certain flame height and angle, both in the vertical and horizontal positions. This assessment is conducted to evaluate the flammability and fire risk of the specimen by measuring factors such as ignition frequency, burning duration, and length of combustion.

Application

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.
