A Diagram Instruction of Glow Wire Test Method for Electrical Appliances You may be a bit of a stranger when it comes to the IEC（International Electrotechnical Commission）, but when it comes to the glow wire (GWT) test, everyone in engineering plastics should have heard about it. We will use diagram to introduce glow wire test which is very normal for electrical appliances. And we will focus on the three subjects below: 1.What kind of product needs GWT testing? 2.Test equipment and related facilities for the GWT testing. 3.What are the GWIT, GWFI and GWT test method? The scorching wire test is a mandatory test for unattended electrical appliances. Its standards and testing methods are formulated by the IEC, which is one of the important standards for the export of electronic products to the European market. Please note: 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 GWT we mention...
