Glow-Wire Tester Type GPG accord. to DIN EN 60695-2-10 and IEC 695-2-1
Application - Fire hazard testing
Principle:
1. The tester serves to investigate the fireresistant properties of materials
and end products.
2.The glow-wire itself is the source of fire. The temperature of
the glow-wire is set and controlled by a temperature controller.
3. During a test thetemperature controller can be operated in a manual mode to
generate a defined voltage signal on the manipulated variable (glow-wire), thus
avoiding a feedback of the reference variable (thermocouple) on the temperature
controller.
4. The temperature of the glow-wire can be set from room temperature to 1000℃.
5. The temperature of theglow-wire is detected by a sheathed thermocouple
type K (class 1)in accordance with IEC 60584-2.
6.During the test the specimen is moved at a constant velocity of 11 mm/sec toward the glow-wire and back. The heating time of 30 sec is quartz controlled.
7. The specimen support is pulled toward the glow-wire with a force of 1 N.
8. The power supply is 230 VAC
Components
1. Test rig mounted on tester Glow-wire
2. Thermocouple
3. Temperature controller with constant voltage output and fuzzy optimizer Linear
