Glow wire test apparatus is the commonly used equipment for testing solid insulating material for fire hazard testing. This test apparatus is covered in IEC 60695-2-10:2021 and commonly referred for various devices in many standards such as IEC 60335, IEC 60695-2-11, IEC 60695-2-12, IEC 60598-1, IEC 60947, IEC 60898, IEC 61008-1, IEC 60669-1, IEC 60884-1, IEC 60950-1 / IS 13252, IEC 60238, IEC 60745-1, IEC 60400, IEC 60730-1, IEC 61050, IEC 60320-1, IEC 61058-1, ASTM D 6194-03 and UL 60745-1. The test is carried out to asses the flammability characteristics of a Product body, typically made up of thermoplasts and thermosets. The glow wire tester is an important tool not just to assess the quality of the Product, but also to continuously check the incoming components related to the Product body for their flammability characteristics. Material moulds manufacturers can use this product to ascertain the quality of the Material under test
