Glowing -Wire Tester Flammability Testing Equipment For IEC60695-2-10 With 4mm Glow-Wire And Button Operation
Standard: IEC60695-2-10 Fire hazard testing – Part 2-10: Glowing/hot-wire based test methods – Glow-wire apparatus and common test procedure, IEC60695-2-11 Fire hazard testing – Part 2-11 : Glowing/hot-wire based test methods – Glow-wire flammability test method for end-products, IEC60695-2-12 Fire hazard testing – Part 2-12: Glowing/hot-wire based test methods – Glow-wire flammability index (GWFI) test method for materials, IEC60695-2-13 Fire hazard testing – Part 2-13: Glowing/hot-wire based test methods – Glow-wire ignitability test method for materials.
Description of the test apparatus: The glow-wire is formed from nickel/chromium (> 77 % Ni/20 ± 1 % Cr) wire, having an overall diameter of 4.00 mm ± 0.07 mm (before bending). The dimensions of the glow wire loop are as detailed in Figure 1.
A new glow-wire shall be annealed for a total of at least 10 h by being subjected to a current of at least 120 A before being used for a test run. The total annealing time may be achieved cumulatively. To avoid damage, the thermocouple shall not be installed during annealing. At the end of annealing, the depth of the thermocouple pocket hole shall be verified. The test apparatus shall be designed so that the glow-wire is kept in a horizontal plane and applies a force of 0.95 N ± 0.1 0 N to the test specimen during the application of the glow-wire. The force shall be maintained at this value when the glow-wire or the test specimen is moved horizontally one towards the other. The penetration of the tip of the glow-wire into and through the test specimen shall be limited to 7 mm ± 0.5 mm.
