EN 60695-11-20 500W火焰測試–標(biāo)準(zhǔn)概述

EN 60695-11-20描述了一種由兩個小型實驗室測試程序組成的測試方法，用于比較電工產(chǎn)品中使用的不同材料的燃燒性能。垂直方向的桿件試樣或水平方向的板件試樣暴露在小的火焰點火源中，標(biāo)稱熱功率為500w。該測試方法使用兩種測試樣品配置來對材料性能進(jìn)行分類。使用矩形條形試樣來評估可燃性和燃燒行為，使用方形板試樣來評估試樣的耐燃性。本測試方法僅適用于根據(jù)IEC 60695-11-10將材料分類為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.
