Single wire and cable vertical combustion test:
The vertical combustion test of a single wire and cable uses a Bunsen burner of specified size and a specific gas source (propane) to periodically burn the vertical test sample at a certain flame height and a certain flame angle, and evaluates its flammability and fire hazard based on the ignition, combustion duration and combustion length of the test sample.
Single wire and cable vertical combustion test equipment applicable scenarios:
The single wire and cable vertical combustion tester is mainly used to evaluate the flammability of single wires and cables with a conductor diameter greater than 8mm (cross-sectional area greater than 0.5mm2) or less than 8mm (cross-sectional area less than 0.5mm2). It is suitable for the research, production and quality inspection departments of electrical and electronic products and their components such as lighting equipment, low-voltage electrical appliances, household appliances, machine tool appliances, motors, power tools, electronic instruments, electrical meters, electrical connectors and accessories.
