LinxiaTH8055 Glow Wire Tester
The TH8055 Glow Wire Tester heats an electric heating wire of specified material (Ni80/Cr20) and shape (a Φ4 mm nickel‑chromium wire) to the test temperature (550°C–960°C) using a high current for 1 minute. It then applies a prescribed force (1.0 N) to vertically press the heated wire against the test specimen for 30 seconds, assessing the ignition risk of finished electrical and electronic equipment by determining whether the specimen and underlying substrate ignite or sustain combustion. The instrument also evaluates the ignitability, glow‑wire ignition temperature (GWIT), flammability, and glow‑wire flammability index (GWFI) of solid insulating materials and other solid combustible substances. The glow wire tester is suitable for research, production, and quality‑control departments of lighting equipment, low‑voltage electrical appliances, electrical instruments, and other electrical and electronic products and their component parts.
