Glow Wire Testing for Fire-Hazard Evaluation
In a glow wire test, a resistance-wire loop is heated to a specified temperature and brought into contact with a test specimen under defined force and timing conditions. Observations are used to evaluate ignition behavior, flame persistence, and related fire-hazard response.
This page includes glow wire test apparatus and replacement items, including glow wire elements, Type K thermocouples, and silver foil for one-point temperature verification.
Standards note: confirm the required element geometry, thermocouple placement, temperature verification, contact force, timing, specimen setup, and acceptance criteria in the applicable standard and clause.

Frequently Asked Questions
What is glow wire test equipment used for?
Glow wire test equipment is used to evaluate fire-hazard, ignitability, or flammability response when a material or component contacts a heated wire under defined test conditions.
What does the silver foil accessory do?
The silver foil is used for one-point verification of glow wire temperature under IEC 60695-2-10.
Why are replacement glow wire elements needed?
Glow wire elements must maintain the required tip geometry and thermocouple-hole arrangement. Replace an element when its condition no longer meets the applicable method or apparatus requirements.
Why is the thermocouple important in glow wire testing?
The thermocouple measures the glow wire temperature. Its dimensions, placement, and condition affect the temperature measurement.
Provide the applicable standard and clause and whether you need a glow wire test apparatus, a replacement element, a thermocouple, or silver foil.
