规定了当单个垂直电气绝缘导线或电缆或光纤电缆处于规定的火灾条件下时，评估下落的燃烧液滴/颗粒的试验程序。 注:如果需要，IEC 60332-1-3的测试可与IEC 60332-1-2的测试同时进行。 建议的性能要求见附录A。 IEC 60332-1-3规定了1 kW预混合火焰的使用，并适用于一般用途，但规定的程序可能不适用于总横截面积小于0.5 mm2的小型单绝缘导线或电缆的测试- 因为导体在测试完成前熔化，或者因为测试完成前电缆断开而测试小型光纤电缆。 具有符合IEC指南104的集团安全出版物状态。

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. Has the status of a group safety publication in accordance with IEC Guide 104.
