Glow Wire Test Apparatus Description
IEC 60695-2-10 Glow Wire Test Apparatus for Flammability Testing
The Glow Wire Test Apparatus is a professional glow wire tester manufactured by KingPo. It is specifically designed to evaluate the resistance of insulating materials and components to non-flame ignition sources by simulating the thermal stress caused by overheated electrical parts or glowing elements in real-world fault conditions.
Widely adopted in the safety assessment of household appliances, lighting equipment, consumer electronics, automotive electronics and electrical accessories, the apparatus enables manufacturers and certification laboratories to determine critical flammability characteristics such as Glow Wire Ignition Temperature (GWIT) and Glow Wire Flammability Index (GWFI). It plays an essential role in material selection, product development, quality control and regulatory compliance, helping to reduce fire hazards and ensure reliable product safety.

Professional Construction & Technical Precision
The Glow Wire Test Apparatus features a high-stability heating circuit with precise current and voltage control (ยฑ2% during test) to maintain the glow wire temperature within ยฑ2ยฐC. The glow wire (ฮฆ4 mm nickel-chromium alloy) is mounted on a precision carriage that advances at a controlled speed of 10โ25 mm/s and applies a constant force of 0.95 N ยฑ0.1 N.
A ฮฆ1.0 mm K-type thermocouple provides real-time temperature feedback. The system includes an independent exhaust system and stable base to ensure safe and repeatable operation. All critical components are manufactured to tight tolerances for excellent long-term stability and measurement repeatability in daily laboratory use.
Testing Principle
The glow wire is heated to the specified temperature (550ยฐC to 1000ยฐC) and pressed against the specimen with 0.95 N force for 30 seconds at a controlled speed. The test evaluates ignition time (Ti), flame persistence time (Te), and smothering time, as well as whether the specimen or underlying bedding material (tissue paper) ignites or shows signs of sustained burning, cracking or melting. These results are used to determine the Glow Wire Ignition Temperature (GWIT) and Glow Wire Flammability Index (GWFI).
Common Error Mitigation
To ensure repeatable and accurate results, always verify the glow wire temperature with the thermocouple before each test and confirm the contact force and speed settings. Use fresh glow wire specimens as recommended and ensure the test specimen is properly positioned. Clean the glow wire and thermocouple regularly to prevent residue buildup that could affect temperature accuracy. Perform periodic calibration of temperature, force and timing systems.
