    Auto Electrical Safety Test Equipment Flame Resistant Test Glow Wire 999s Burning Time Adjustable

    Auto Testing Machine Flame Resistance Test Glow Wire Testing Equipment with 999s Burning Time Adjustable


    1. Standard of Glow Wire Testing Equipment:

    It is according to IEC60695-2-1, IEC60695-2-10~IEC60695-2-13 (GB/T5169.10-2006~GB/T5169.13-2006), < basic testing methods of Glow wire, basic testing methods of Glow wire device> and UL 746A, IEC829, DIN695, VDE0471


    2. Introduction of Glow Wire Testing Equipment

    Glow wire testing equipment is suitable for resistance to abnormal heat and fire test on lighting lamps, electronic products and household appliances. Adopting imported instrument display, with easy operation, stable performance the equipment is applicable to flame resistance tests of all levels of QC departments and corresponding enterprises.


    Glow wire testing is an electrical safety test designed to evaluate the flame resistant properties of plastic materials used in electrical devices. Its purpose is to protect against the risk of fire from overheated or electrically energised parts which may cause the plastic material to ignite. This may occur in normal use, under reasonable abnormal use, malfunction or failure of the product. The glow wire simulates an over-heated part which then comes into contact with plastic materials


    The glow wire tester is designed according to IEC60695-2-10, UL746 and GB/T5169.10. The specific material and sharp heating wire is heated to specific temperature (550 ℃~960 ℃) for 1 min by max current, then vertical burns the EUT with certain pressure (0.95N) for 30s, then check if the test specimen and bedding material are burning, and count the burning time to judge the dangerousness of the specimen. Generally it is applied to test flammability, GWIT and GWFI of lighting lamps, electronic products and household appliances.

    What is Glow Wire Testing?

    Glow wire testing is an electrical safety test designed to evaluate the flame resistant properties of plastic materials used in electrical devices. IEC60695-2-11 describes the glow-wire test conducted on end products (the GWEPT, or glow-wire end product test). Its purpose is to ensure the end product does not ignite or spread flames should an ignition source (such as an overheated part) come into contact with the plastic material. This may occur in normal use, under reasonable abnormal use, malfunction or failure of the product. The glow wire simulates an over-heated part which then comes into contact with plastic materials.


    In this part of the standard, the specimen to be tested is the end product, preferably the entire product if this is possible. The glow wire is either applied to the area most likely to come into contact with an ignition source, or the area of the product where the plastic material is the thinnest. The glow-wire is heated to the required temperature, which is given in the individual product standards, and then applied to the specimen for 30 seconds. It is then removed, and the specimen is observed for a further 30 seconds.


    The Standard

    The glow wire test is covered by the International Electrotechnical Commission (IEC) standard IEC 60695-2 Fire Hazard Testing, with four parts covering four different aspects of the glow-wire test. These are:


    IEC 60695-2-10: Glow-wire apparatus and common test procedure

    IEC 60695-2-11: Glow-wire flammability test method for end products (GWEPT)

    IEC 60695-2-12: Glow-wire flammability index (GWFI) test method for materials

    IEC 60695-2-13: Glow-wire ignition temperature (GWIT) test method for materials

    The British and European equivalent of the glow wire standard is BS EN 60695-2


    Apparatus


    The apparatus includes:


    The glow wire, Circuit to heat the wire, System to measure the temperature of the wire, Piece of tissue paper to catch any falling debris, Draught-free test chamber, Timing device, Clamped or mounted specimen, Ruler to measure flame height


    Test Procedure


    The test is conducted by first heating the glow-wire to the required temperature. Either the specimen is then brought into contact with the tip, or the tip is moved into contact with the specimen. Observations and results are then recorded in accordance with the relevant glow-wire standard.


    Observations

    Whether ignition occurs

    If ignition occurs, how long this took to happen

    The time it takes for the flames to extinguish

    If the sample is completely consumed by the flames

    Whether the tissue underneath the sample was ignited by falling debris

    The specimen passes the test if either a) it does not ignite or b) the flames extinguish within 30 seconds of the removal of the glow wire and the tissue underneath does not ignite.
