Glow Wire Tester TF346
Glow Wire Tester, to determine the resistance to fire insulating parts.
Glow Wire Tester, to determine the fire hazard of electrical parts and components subjected to malfunctions such as overload, short circuit, poor connection, or others that may ignite and spread the flame to the rest of the product.
The Glow-Wire Tester simulates an overloaded resistor or other ignition source and applies heat to the specimen for a short period of time, and simulates as closely as possible actual effects occurring in practice.
A temperature controller is fitted with the thermocouple supplied, accurately measuring the glow wire temperature. The electrical circuit of the control unit is fully protected by fuses and a miniature circuit breaker. TESTEX Glow-Wire Test equipment is a fully automatic instrument contained in its own cabinet to maximize the safety of the operator, and large viewing window and black colored walls ensure convenient observation.

IEC 60695-2-10: glow wire test apparatus and common test procedure (glow wire test method)
The glow wire test for plastics is to determine the resistance to fire insulating parts. And the glow wire test simulates the situation of what the plastics material will happen when contact with a over-heated part.

Glow wire test procedure
- The glow wire temperatureshould be set up first. Heating the glow wire to reach the required temperature.
- Move the glow wire to contact with the specimen.
- Record the result accord to the glow wire test standard.
