| Temperature of the tip of glow-wire | Electric current |
| 550ºC | 65A~75A |
| 650ºC | 80A~90A |
| 750ºC | 95A~105A |
| 850ºC | 110A~120A |
| 960ºC | 130A~140A |
1 Work Principle
1) After putting the test specimen to the fixture, test specimen could be driven by electronic engine and could go left or right automatically control in the test process.
2) Mount glow wire. Test specimen carriage turns right to glow wire with hammer pulling the carriage in order to keep the force within 1 newton. The force shall be maintained at this value when the glow-wire or the test specimen is moved horizontally one toward the other. The penetration of the tip of the glow-wire into the through the test specimen shall be limited to 7mm.
3) Application time that glow wire tip is applied to the test specimen is controlled by numeric relay beforehand.
4) Ignition time is measured by numeric and controlled by button.
5) Flame extinguishing time is measured by numeric relay and controlled by button.
6) Glow wire temperature is controlled by adjusted glow wire current and measured precisely by Temperature controller.
