着火条件下电缆和光缆的试验.第1-3部分:单根绝缘电线或电缆垂直火焰蔓延的试验.火焰熔滴/颗粒测定规程

[中文适用范围]： 指定了当单个垂直电绝缘导体或电缆或光纤电缆受到规定的火灾条件时评估掉落的燃烧液滴/颗粒的测试程序。注 - 可以执行 IEC 60332-1-3 测试 [外文原描述]： IEC 60332-1-3:2004 Specifies a test procedure for assessment of falling flaming droplets/ particles when a single vertical electrical insulated conductor or cable, or optical fibre cable, is subjected to defined fire conditions. NOTE - Testing to IEC 60332-1-3 may be performed simultaneously with that to IEC 60332-1-2, if required. Recommended requirements for performance are given in Annex A. IEC 60332-1-3 specifies the use of a 1 kW pre-mixed flame and is for general use, except that the procedure specified may not be suitable for the testing of small single insulated conductors or cables of less than 0,5 mm2 total cross-section because the conductor melts before the test is completed, or for the testing of small optical fibre cables because the cable is broken before the test is completed.
