Glow Wire Testing: Ensuring Safety and Reliability of Engineering Plastics

In electrical and automotive applications, plastic materials may face unexpected high-temperature conditions caused by electrical overload, component failure or poor connections.

To ensure safety and reliability, engineering plastics need to pass strict flame resistance tests. Glow wire testing is one of the important evaluation methods used to verify the fire safety performance of plastic materials.

What Is Glow Wire Testing?

Glow wire testing is a material safety test that simulates the heat generated by abnormal conditions in electrical equipment.

During the test, a heated wire reaches a specified temperature and contacts the plastic sample. Engineers then evaluate:

• Ignition time
• Flame duration
• Self-extinguishing performance
• Burning behavior
• Material deformation

This test helps determine whether plastic materials can withstand high-temperature environments without causing fire hazards.

Why Glow Wire Testing Is Important for Engineering Plastics?

Engineering plastics are widely used in electrical components, automotive systems and new energy products.

Materials with excellent glow wire performance can provide:

1. Improved Fire Safety

Flame-retardant plastics reduce the risk of ignition and help products meet international safety requirements.

2. Stable Performance Under High Temperature

Materials maintain mechanical properties even under abnormal heat conditions.

3. Compliance With Industry Standards

Glow wire testing is commonly applied according to standards such as:

• IEC 60695-2-10
• IEC 60695-2-11
• GB/T 5169
