IEC 60332-3-23:2018标准规定了垂直安装的成束电线或电缆的垂直火焰蔓延测试的类别B。该测试适用于电线或电缆的垂直安装,以评估其在火灾条件下的火焰蔓延性能。该测试的目的是确定电线或电缆在火灾条件下的火焰蔓延速度和火焰蔓延距离,以评估其在火灾条件下的安全性能。

该测试的样品应该是成束电线或电缆,其长度应该为2.5m,且应该在垂直方向上安装。测试时,样品应该被放置在一个垂直的燃烧器中,该燃烧器应该符合IEC 60695-11-5标准中的要求。测试时,燃烧器应该点燃样品的底部,然后记录火焰蔓延的速度和距离。

IEC 60332-3-23:2018标准规定了测试的分类,其中类别B是指测试时使用的燃烧器的火焰高度为1m,且测试时的氧气浓度为21%。该测试的结果应该记录在测试报告中,包括火焰蔓延速度和距离。

该标准的测试方法可以用于评估电线或电缆在火灾条件下的安全性能。该测试可以帮助制造商和用户选择符合其需求的电线或电缆,并确保其在火灾条件下的安全性能符合要求。
