GWP offers you fire examinations in accordance with IEC 60695-2 (filament examination). Becomes the after-burning time at a defined one working duration as well as the decreasing of burning drops or glowing parts determines. This examination can be carried out also at pure material tests. Here the filament inflammability number (GWFI) is when the highest testing temperature at which the flames or glowing events go out after the remove of the filament within 30 s determines without the inflammation of the fixed pad by burning drops or glowing parts. This examination makes a comparison of their inflammability from different materials possible.
