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, the test can also be applied in the automotive, marine, construction and other industries.
In the home appliance industry, in order to ensure the correct use of electrical appliances, overheating and short circuit safety, glow wire testing equipment> is a widely used electrical safety testing instrument. It evaluates the flammability performance of plastic materials when they come into contact with overheated parts by using a glow wire to test the flammability of plastic materials to ensure that the materials used in electrical appliances have good fire performance. In addition, this safety test can also be used in the evaluation of safety requirements in the automotive, marine, construction and other industries. The effective application of the glow wire test helps to improve the safety of products in industries such as electrical appliances, automobiles, ships and construction, thereby reducing the risk of fire.
The glow wire test is an important tool used to evaluate the flammability of materials, and there are four sections covering four different aspects of the glow wire test.
IOS5169.10 Glow Wire Test Apparatus> and general test procedures require a standard glow wire apparatus and test protocol to test materials for flammability.
The glow wire flammability test method (GWEPT) of IEC60695-2-11 for final products 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, 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, which covers four parts in the IOS5169.10-13 chapter, including the glow wire device and general test procedures, Glow-wire flammability test method (GWEPT) for final products, Glow-wire flammability index (GWFI) test method for materials and Glow-wire ignition temperature (GWIT) test method for materials. The glow wire test can be used to evaluate the flammability of materials and products, but it is required to follow the test regulations of IOS5169.10-13 and use standard glow wire equipment and test 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 Test Equipment> uses a heating element called a glow wire to heat the sample to be tested, pressing the element into the sample material with a set force of 1N for 30 seconds. The GWT test will assess whether a sample will ignite within 30 seconds of the heating element being removed, while the GWFI and GWIT tests will assess the flammable temperature range of the material within 30 seconds of the heating element being 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 a 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. 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 used in unattended or attended appliances that draw less than 0.2A are subject to a less stringent test method. Manufacturers of electrical appliances therefore need to know the classification of their products in order to perform proper testing according to IEC 60335-1.
LISUN Instruments is well-known in the industry for research and development of various building materials, electronic and electrical products, and plastic material flame-retardant and fire-resistant test equipment. Its main products are glow wire test equipment>, needle flame tester, horizontal and vertical burning tester, tracking tester and single wire and cable burning tester, etc.
