Glow wire test equipment> can be used for fire protection evaluation of electrical equipment. It is designed to simulate fires that devices can cause when overheated, and to test the flammability of plastic materials. The test uses a glow wire to simulate an overheated part, measuring the reaction of plastic materials upon contact. If the material does not ignite when it comes into contact with the glow wire, the material is considered flame retardant. In the home appliance industry, this test is widely used to evaluate the flammability of various plastic materials and cables used in electrical components to ensure product safety. In addition, this test can also be applied to automobile, shipbuilding, construction and other industries.
In the home appliance industry, in order to ensure the correct use of electrical appliances and the safety of overheating and short circuits, glow wire testing equipment> is a widely used electrical safety testing instrument. It uses a glow wire to conduct flammability testing on plastic materials to evaluate the flammability performance of plastic materials when they come into contact with overheated parts to ensure that the materials used in electrical appliances have good fire resistance. In addition, this safety test can also be used to evaluate safety requirements in industries such as automobiles, ships, and construction. The effective application of glow wire testing can help improve the safety of products in the electrical, automotive, marine and construction industries, thereby reducing the risk of fire.
Glow wire testing is an important means used to evaluate the flammability of materials. There are four parts covering four different aspects of glow wire testing.
IOS5169.10Glow wire test equipment> and general test procedures require the use of standard glow wire equipment and test protocols to test whether materials are flammable.
The glow wire flammability test method (GWEPT) of final products of IEC60695-2-11 is used to test the flammability of physical products, through which the flammability of physical products can be evaluated. IEC60695-2-12, GHFI material glow wire flammability index test, is used to test the flammability of the material itself.
IEC60695-2-13, GWIT, glow wire ignition temperature for materials, used to test the ignition temperature of materials.
The glow wire test is an important part of the International Electrotechnical Commission (EC) standard IEC60695-2 fire hazard test. It covers the four parts in the IOS5169.10-13 chapter, including the glow wire device and general test procedures, Glow Wire Flammability Test Method for End Products (GWEPT), Glow Wire Flammability Index (GWFI) Test Method for Materials, and Glow Wire Ignition Temperature (GWIT) Test Method for Materials. Glow wire testing can be used to evaluate the flammability of materials and products, but it is required to follow the testing regulations of IOS5169.10-13 and use standard glow wire equipment and testing methods for testing. Passing the glow wire test equipment> test can provide a reliable basis for the testing and evaluation of fire hazard substances.
According to the IEC 62153-1 specification, the glow wire test is a test method used to detect the safety of household appliances. This test method must be carried out in accordance with the requirements in the IEC 60695-2 series of specifications. The glow wire test includes a variety of tests, including GWT (IEC60695-2-11), GWFI (IEC 60695-2-12) and GWIT (IEC 60695-2-13). The GWT test is designed to test the flammability of the final product, while the GWFI and GWIT tests are designed to test the flammability of the raw material.
Glow wire testing equipment> Uses a heating element called a glow wire to heat the sample to be tested, and presses the element into the sample material using a set force of 1N for 30 seconds. The GWT test will evaluate whether a sample will ignite within 30 seconds after the heating element is removed, while the GWFI and GWIT tests evaluate the material's flammable temperature range within 30 seconds after the heating element is removed. All of the above glow wire test methods specify a specific flammable temperature range as well as ignition time and burning height to determine the safety of the product or raw material.
The glow wire test method specified in IEC 60335-1 is an effective tool for safety assessment of household appliances. By using GWT, GWFI, and GWIT tests to identify material flammability, products can be checked for compliance with flammability standards, improving safety. According to the provisions of glow wire ignition testing in IEC 60695-2-11, IEC 60695-2-12 and IEC 60695-2-13 series of specifications, manufacturers may use reasonable glow wire test equipment> to Ensure the safety of household appliances.
IEC 60335-1 is a general safety specification governing the safety of household appliances. This specification specifies the glow wire test for testing the flammability of non-metallic connectors used and determines the severity of the test. In this specification, electrical appliances classified as unattended, such as refrigerators, cooking appliances, dishwashers,For washing machines and dryers, connectors with a current greater than 0.2A need to undergo the most stringent evaluation, including materials that meet GWF850°C, final products that pass the 850°C glow wire test, and materials that meet GWIT 775°COR, pass The final product of the 750°C glow wire test. Connectors classified as being used in appliances that draw less than 0.2A and are left unattended or attended are subject to a less stringent test method. Therefore, electrical appliance manufacturers need to understand the classification of their products in order to conduct correct testing according to IEC 60335-1.
