This semi-automatic testing system with glow wire is used to perform tests on plastics to IEC/DIN EN 60695-2-12 GWFI or IEC/DIN EN 60695-2-13 GWIT.
During these tests, the fire behavior of plastics is determined using a glow wire. In the process, the glow wire is pressed against a circular plastic plate. The result is then included as a characteristic value in the properties of the plastic.
Tests to IEC/DIN EN 60695-2-12 determine the Glow Wire Flammability Index (GWFI).
In a glow wire temperature range from 550°C to 960°C, this is the highest test temperature at which flames or smoldering material self-extinguish within 30 seconds of removing the glow wire. Tissue paper placed underneath the specimen must not be ignited by burning droplets. The specimen itself must not ignite either.
