IEC 60695-2-10 Glow Wire Tip | Glow Wire for Flammability Testing

IEC60695-2-10-2021 Glow Wire Tip, Glowing/hot-wire based test methods-Glow Wire

The IEC 60695-2-10 Glow Wire Tip serves as the heating element in glow wire flammability testing. It is heated to a specified temperature and applied to test specimens to assess their ignition resistance and flame behavior under controlled conditions.

This Glow Wire Tip is precision-formed from high-grade Nickel/Chromium alloy to maintain dimensional stability during repeated high-temperature exposure. Proper annealing during the manufacturing process helps prevent fine cracking at the tip, ensuring reliable performance and extended service life in laboratory testing environments.

Technical Parameters

Professional Construction & Technical Precision

The IEC 60695-2-10 Glow Wire Tip is precision-manufactured from high-purity Nickel/Chromium alloy to maintain excellent dimensional stability and thermal performance at elevated temperatures. The tip geometry is carefully formed to meet the strict requirements of IEC 60695-2-10, ensuring uniform heat application during testing.

To enhance durability, annealing is applied during the forming process. This treatment helps minimize the risk of fine cracking at the tip, which is critical for maintaining measurement accuracy and extending the service life of the Glow Wire Tip under demanding laboratory conditions.

Testing Principle

In glow wire testing, the IEC 60695-2-10 Glow Wire Tip is electrically heated to a specified temperature and then applied to the test specimen under defined force and duration. The test assesses the material’s tendency to ignite and the duration of any sustained flaming after the heat source is removed.

Consistent tip dimensions and material properties are essential for achieving reliable and repeatable test results. Variations in tip condition or geometry can lead to inconsistent heat transfer, which may affect the accuracy and reproducibility of flammability evaluations across different laboratories and operators.

Common Error Mitigation

To ensure accurate and consistent glow wire test results, the following practices are recommended:

• Use a properly calibrated thermocouple to accurately monitor and control the glow wire temperature throughout the test.
• Inspect the Glow Wire Tip before each use to ensure it is free from deformation, oxidation, cracks, or surface damage.
• Perform proper annealing when forming new tips to reduce the risk of fine cracking during high-temperature operation.
• Regularly check the condition of the tip, particularly after prolonged or high-temperature testing, and replace it when wear is evident.
• Maintain correct alignment and consistent contact force between the glow wire and the test specimen during testing.
• Replace the Glow Wire Tip promptly when signs of wear, inconsistent heating, or dimensional deviation are observed.
