This method is used to determine the glow wire flammability index of a test specimen by means of a glow wire loop.

Test setup

 

Pre-treatment:
48h / 23°C / 50 % relative humidity

 

Test temperature in °C	550	600	650	700	750	800	850	900	960
Exposure time	30 s

The specimen is considered to have passed the test if the following conditions are satisfied:

• The longest sustained flame or glow is extinguished within 30 s of removing the glow wire tR
• The specimen is not completely burned
• The tissue paper does not ignite
