DJC-1 wire and cable vertical burning test equipment Introduction
The single wire and cable vertical burning tester is mainly for the flammability of a single wire and cable with a conductor diameter greater than 8 mm (cross-sectional area greater than 0.5 mm2) or less than 8 mm (cross-sectional area less than 0.5 mm2). 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 tools, electrical machinery, power tools, electronic instruments, electrical instruments, electrical connectors and accessories. Features
The single wire and cable vertical burning test uses a Bunsen burner of a specified size and a specific gas source (propane) to ignite the sample in a vertical state at a certain flame height and a certain flame angle. Test igniting, duration of combustion, and length of combustion are used to assess flammability and fire hazard. Technical Parameters
