Glow Wire Connectors and Testing Video - Molex

Q: What is a Glow Wire Connector?

A: Glow Wire capable testing became a mandatory requirement in 2001 for certain home appliances sold in Europe. This International Safety Standard (IEC/EN 60335-1 5th Edition) was issued by the International Electrotechnical Commission. Legislation may soon expand to other regions.

All connectors in unattended appliances carrying a current greater than 0.20A must pass the Glow Wire test. The Glow Wire test measures ignition resistance of the plastic connector material. To pass the test, a connector housing must withstand 30 seconds of an applied glowing wire at a temperature of 750°C and not ignite, or if ignition occurs it must self extinguish within 2 seconds, alternatively the connector housing must be made from a material that meets or exceeds the required GWFI and GWIT requirements as detailed in the IEC/EN 60335-1 5th Edition standard. A connector that is just UL94 V-0 or V-2 rated does not necessarily meet Glow Wire requirements.

Glow-Wire products are manufactured from materials that have specific ratings and are tested by independent agencies.
