Glow wire testing is an electrical safety test designed to evaluate the flame resistant properties of plastic materials used in electrical devices. Its purpose is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite. This may occur in normal use, under reasonable abnormal use, malfunction or failure of the product. The glow wire simulates an over-heated part which then comes into contact with plastic materials.
The purpose of glow wire testing is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite.this test is mainly for products sold in the European market, as the IEC is based in Europe (Geneva, Switzerland) rather than the United States.
The glow wire testing we mentioned is actually made up of three tests in the IEC60335 standard (GWIT, GWFI, GWT), which are somewhat similar, but not the same. Therefore, GWT is a bit more complicated than UL flame retardant tests.
Glow wire tester-This instrument adopts steel structure of spraying, imported instrument display, easy operation, stable performance,suitable for the quality inspection departments at all levels and relevant enterprises to use fire resistant test.
