Brief Introduction
Glow wire test is a simulation experiment project using non-flame ignition source in accordance to standard requirements of IEC60695-2-10,UL 746A ,GB/T5169.10,GB4706.1.It makes required material(Ni80/Cr20) and heating wire in required shape(Φ4mm-chromel-filament)heated up to test temperature( 550 ℃ ～ 960 ℃) for 1min and then broil the specimen using required pressure (1.0N) for 30s at vertical direction;to check whether the specimen and bedding material ignite and lasting ignition time to test the ignition fatalness of electrical and electronic finished devices
Test the ignition performance,ignition temperature (GWIT),solid insulating material and other solid combustible material,combustibility and flammability index(GWFI) .
It can be applied to research,production and quality testing department of electrical and electronic devices and component parts like lighting equipment,low voltage apparatus,eletrotechnical instrument,etc.
