Glow wire testing equipment> can be used to evaluate the fire protection of electrical equipment. It is designed to simulate the fires a device can cause when overheated and to test the flammability of plastic materials. The test uses a glow wire to simulate an overheated part and measures how the plastic material reacts when it comes into contact. If the material does not catch fire when it comes into contact with the glow wire, it means that the flame retardant performance of the material meets the standard. 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 test is an important means to evaluate the flammability of materials. The four sections cover 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 the International Electrotechnical Commission (EC) standard IEC60695-2 is an important part of the fire hazard test, which covers the four parts in the IOS5169.10-13 chapter, including the glow wire device and general test procedures, the glow wire flammability test method (GWEPT) of the final product, the material Glow Wire Flammability Index (GWFI) test method 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. 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 performed in accordance with the requirements in the IEC 60695-2 series of specifications. Glow wire testing includes a variety of tests, including GWT (IEC 60695-2-11), 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 raw materials.
Glow wire testing equipment> Use a heating element called a glow wire to heat the sample to be tested, and use a set force of 1N to press the element into the sample material 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. Appliances classified as unattended in this specification, such as refrigerators, cooking appliances, dishwashers, washers and dryers, using connectors with currents greater than 0.2A are subject to the most stringent evaluation, withIncluding materials that comply with GWF850°C and final products that pass the 850°C glow wire test, and materials that comply with GWIT 775°COR and final products that pass 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.
