Description of the instrument
IEC 60332 Single Insulated Wire or Cable Vertical Flammability Tester is used for conductor diameter greater than 8mm (cross-sectional area greater than 0.5mm2) or less than 8mm (cross-sectional area less than 0.5mm2) of the single wire and cable flammability assessment. It is suitable for the research, production and quality inspection departments of electrical and electronic products and components such as lighting equipment, low voltage electrical appliances, household appliances, machine tools, electrical appliances, electric tools, electronic instruments, electrical instruments, electrical connectors and accessories. In line with IEC 60332.

Why is flammability testing important?
In order to minimize the risk of fire or explosion, it is important to evaluate the flammability characteristics of the material to understand key characteristics such as the lower flammability limit, upper flammability limit, limiting oxygen concentration and deflagration index.
