Features
To test the resistance to fire of insulating parts and assesses the susceptibility of electrical insulating materials to ignition as a result of exposure to a glowing wire according to IEC 60695-2-10: Glowing/hot-wire based test methods - Glow-wire apparatus and common test Procedure ASTM D6194: Standard Test Method for Glow-Wire Ignition of Materials UL746A: Testing for the resistance to ignition of polymeric materials.IEC60950-1, IEC60335-1, IEC60884-1, IEC60238, IEC60695-2-11, IEC60695-2-12, IEC60745-1, IEC60400, IEC60730-1, IEC60598-1, IEC61050, IEC60320-1, IEC61058-1, IEC60742, IEC60669-1.
This test method determines the minimum temperature required to ignite a material by the effect of a glowing heat source, under the specified conditions of test. Inside the Glow Wire Test Apparatus, a resistance wire (glow-wire) is electrically heated to a specified temperature which is adjustable.The specimen is brought into contact with the glow-wire by a motor-driven sliding carriage. At the end of a prescribed time the specimen is automatically returned to the starting position.
Observations and measurement are made to evaluate the Glow Wire Flammability Index (GWFI) and Glow Wire Ignition Temperature (GWIT) presented by the specimen during exposure to elevated temperatures.
