The Glow Wire Test Temperature for Appliance Couplers for Household and Similar General Purposes
According to IEC 60320 clause 27 ,for accessories with a rated current exceeding 0,2 A compliance is checked by the glow wire tester:
to ensure that an electrically heated test wire under defined test conditions does not cause ignition of insulating parts or to
ensure that a part made of insulating material, which might be ignited by the heated test wire under defined conditions,
burns for a limited time only and that without spreading fire by flame, or burning parts, or drops falling down from
the part under test.
The following test temperatures, selected from the preferred test temperatures specified in clause 6 of IEC 60695-2-11,
IEC 60695-2-12 and IEC 60695-2-13 are applicable
-750 °C for parts made of insulating material intended to retain current- carrying parts and parts of the earthing circuit in
position;
– 650 °C for all other parts made of insulating material.
The glow wire tester ZLT-GTR produced by Zhilitong Electromechanical Co., Ltd, is in compliance with above requirements of IEC 60320 and IEC 60695-2-11.
