  • The glow wire test is a physical thermal testing test method for plastics.Glow wire testing is used to test plastic sheets or components for their flammability. The test sample is exposed to a selected high temperature load in a defined time window. Glow-wire apparatus and common test procedure), parts of solid insulating materials are ignited by glowing wires. A nickel/chromium wire is heated to 960°C and the insulating material is pushed against it with a force of 1 Newton. It is checked that the insulating material does not attain a certain temperature or catches fire so as to prevent fire hazard in their vicinity.

    What is glow wire test?
    The Glow wire tester ZRS-3H/ZRS-3HS is suitable for resistance to abnormal heat and fire test on lighting lamps, electronic products and household appliances. It uses high-temperature coating spraying on steel structure and imported instrument display, with easy operation and stable performance. The glow wire testing equipment is applicable to flame resistance test of all levels of QC departments and corresponding enterprises.

    What is glow wire capable?
    The glow wire tester uses simulation technology to evaluate the fire hazard caused by thermal stress caused by heat sources such as hot components or overload resistors in a short period of time. It is one of the series of electrical and electronic components fire hazard test instruments. It is suitable for evaluating the flammability test and light-off temperature test of electrical equipment and its components and parts, as well as solid electrical insulating materials or other solid flammable materials.
