Glow Wire Tester:
Product Details: Model ZLT-GTR
This Glow Wire Tester is designed to assess the fire resistance of materials through a fire hazard test, in accordance with international standards such as IEC60695-2-10 (2013), IEC60335, and IEC60598. The testing process involves simulating an ignition source using an electrically heated wire loop, which is pressed against the sample with a consistent force. A miniature jacket thermocouple is used to monitor the temperature of the wire loop accurately.
The sample is securely mounted on a carriage that applies a controlled force of 0.95N via a tensioning cord. This setup ensures accurate and repeatable test conditions. Scales are included for measuring flame height and the depth of penetration. Below the wire loop, a pine wood board covered with tissue paper is placed to evaluate the potential for fire spread due to burning or glowing particles falling from the tested material.
Calibration is performed using silver foil; when the foil melts, the measuring unit should display a temperature of 960°C. This ensures the accuracy and reliability of the test results.
Standard Equipment Included:
- One nickel-chromium wire loop (Φ 4 mm) according to IEC60695-2-10 figure 1, complete with a clamping mechanism and a Φ 1.05 mm hole for the thermocouple.
- One carriage with a specimen fixture, featuring a controlled approach and withdrawal speed of 10–25 mm/s.
- A fine rope pull mechanism with weights to apply a load of 0.95 ± 0.2 N.
- A 7 mm depth penetration gauge with a maximum pointer and stop.
- A scale for measuring flame height.
- A high-current isolating transformer to heat the wire loop, equipped with a variable ratio transformer for precise temperature control up to 960 ± 15°C.
