[0001] This application relates to the field of testing equipment technology, and in particular to a glow wire ignition tester. Background Technology
[0002] To ensure that selected materials possess sufficient flame-retardant properties in their intended application environments, it is necessary to evaluate their ignition performance through a glow wire test during the material selection and design process. The glow wire tester is a testing instrument used for material combustion testing. Designed and manufactured according to the requirements of the "Glow Wire Test Method" in the glow wire test standard, it is suitable for fire hazard testing of electrical and electronic products, household appliances, and their materials. It is also used for ignition testing without a flame ignition source to determine the glow ignition temperature, flammability, and flame resistance index of relevant materials.
