GB/T 5169.17 Fire hazard testing for electric and electronic products – Standard

GB/T 5169.17 Fire hazard testing for electric and electronic products, Part 17: Test flames-500 W flame test method

GB/T 5169.17 Fire hazard testing for electric and electronic products – Scope

This part of GB/T 5169 describes a test method consisting of two small-scale laboratory test procedures which is intended to compare the burning behaviour of different materials used in electrotechnical products. Vertically oriented bar specimens or horizontally oriented plate test specimens are exposed to a small flame ignition source with a nominal thermal power of 500W. The test method uses two test specimen configurations to classify material performance. Rectangular bar-shaped test specimens are used to assess ignitability an burning behaviour, and square plate test specimens are used to assess the resistance of the test specimen to burn-through, as defined in 8.3.3. This test method only applies to materials that have been classified as V-O or V-1 according to IEC 60695-11-10

This test method is only applicable to solid and cellular materials that have an apparent density of more than 250 kg/m3, determined in accordance with ISO 845. The method does not apply to materials that shrink away from the applied flame without igniting due to their thinness.
