What is BS EN 60695-11- 20 - Fire hazard testing about?
BS EN 60695-11-20 describes a test method consisting of two small-scale laboratory test procedures which are intended to compare the burning behaviour of varied 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 500 W. The test method uses two test specimen configurations to classify material performance. Rectangular bar-shaped test specimens are used to assess ignitability and 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-0 or V-1 according to
