BS EN IEC 60332-3-22:2018 - TC标准是一项非常重要的测试标准，它主要用于测试电缆和光纤电缆在火灾条件下的垂直燃烧性能。该标准适用于垂直安装的成束电线或电缆，属于A类，即适用于电缆或光纤电缆在火灾条件下需要保持功能的场合。

该标准的测试方法是将电缆或光纤电缆垂直安装，然后在其下方点燃一定长度的火焰，观察火焰在电缆或光纤电缆上的燃烧情况。测试时需要记录电缆或光纤电缆的燃烧速度、燃烧时间、燃烧长度等参数，以评估其垂直燃烧性能。

该标准的要求非常严格，电缆或光纤电缆在测试过程中不能出现燃烧滴落、燃烧延续、燃烧后自熄等现象，否则将无法通过测试。通过该标准的测试，可以评估电缆或光纤电缆在火灾条件下的燃烧性能，为其在实际应用中提供保障。

除了BS EN IEC 60332-3-22:2018 - TC标准外，还有一些相关的标准也与电缆和光纤电缆的燃烧性能有关，包括：
