EN 60695-11-20 500W火焰测试–标准概述
EN 60695-11-20描述了一种由两个小型实验室测试程序组成的测试方法，用于比较电工产品中使用的不同材料的燃烧性能。垂直方向的杆件试样或水平方向的板件试样暴露在小的火焰点火源中，标称热功率为500w。该测试方法使用两种测试样品配置来对材料性能进行分类。使用矩形条形试样来评估可燃性和燃烧行为，使用方形板试样来评估试样的耐燃性。本测试方法仅适用于根据IEC 60695-11-10将材料分类为V-0或V-1的材料。
Scope:
This part of IEC 60695 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 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 IEC 60695-11-10.
