IEC60695-2-10 High Precision Electrical Safety Test Equipment 1000℃ Glow Wire Test Apparatus
1. Introduction
The glow wire test apparatus is designed according to IEC60695-2-10, UL746 and GB/T5169.10. The specific material and sharp heating wire is heated to specific temperature (550 ℃~960 ℃) for 1 min by max current, then vertical burns the EUT with certain pressure (1.0N) for 30s, then check if the test specimen and bedding material are burning, and count the burning time to judge the dangerousness of the specimen. Generally it is applied to test flammability, GWIT and GWFI of lighting lamps, electronic products and household appliances The equipment is applicable to flame resistance test of all levels of QC departments and corresponding enterprises.
