What is glow wire rating?
The Glow Wire Flammability Index (GWFI) is the highest temperature at which the material does not ignite or self-extinguishes within 30 seconds after removal of the heated element.
Is standard for glow wire test?
The glow wire test is covered by the International Electrotechnical Commission (IEC) standard IEC 60695-2 Fire Hazard Testing, with four parts covering four different aspects of the glow-wire test.
What is glow wire ignition temperature?
The glow wire ignition temperature is the temperature that is 25 °C higher (30°C higher if between 900°C and 960°C) than the highest temperature measured at the end of the glow wire. End product. This test is used to determine the flammability of end products. Pre-treatment: 24 h/23 °C/50 % rel.
What is Gwept?
1. GWEPT stands for glow wire on end product test (IEC 60695-2-11). GWEPT is used when glow wire testing is performed in the manner from how the product is sold and applied in application. GWIT stands for glow wire ignition temperature (IEC 60695-2-13).
What is needle flame test?
This method is used to test and assess the fire hazard presented by a plastic material using a needle flame. In particular, it calculates the severity, in other words the exposure time to the flame after which the material will just about meet the specified requirements. …
What is GWIT?
GWIT stands for glow wire ignition temperature (IEC 60695-2-13). This is a property associated with raw material used in the end product. This property is determined by conducting the glow wire test on a test plate of a raw material of a given thickness.
What is glow wire compatible?
Glow wire compatibility is a test that ensures safety and avoids mishaps caused by human mishandling, over-current, or short circuit failures especially within appliance wiring systems. Glow wire test is made mandatory under the IEC 60335-1 safety standards.
Why we do needle flame test?
What are the requirements for glow wire testing?
Glow wire requirements for home appliances are specified in IEC 60335-1. However, the actual glow wire test methodology is covered in the IEC 60695-2 series of specifications. Glow wire testing is performed by heating an element to a pre-determined temperature. The heated element is referred to as the glow wire.
How are glow wire connectors different from UL 94?
Connectors are involved in the section “Resistance to Heat and Fire” since they are “parts of insulating material supporting live parts”. The Glow Wire test measures ignition resistance of the plastic connector material. This is different from UL-94 testing.
Are there any glow wire compliant connectors from Molex?
Molex currently offers 500 connectors molded in materials that conform to the IEC Glow-Wire Ignition Temperature (GWIT) and the IEC Glow-Wire Flammability Index (GWFI) standards, and we are adding more everyday.

What does GWFI stand for in glow wire testing?
Page 3 of 8 2. GWFI stands for Glow Wire Flammability Index (IEC 60695-2-12). This is a property associated with raw material used in the end product. This property is determined by conducting the glow wire test on a test plate of a raw material of a given thickness.
