IEC 60332-2-2:2004标准是一项测试电缆和光纤电缆在火灾条件下的垂直火焰传播性能的标准。该标准适用于单根小绝缘电线或电缆，测试程序为扩散火焰测试。

该标准要求测试样品必须符合特定的尺寸和形状要求，并且必须在特定的测试条件下进行测试。测试条件包括火焰高度、燃烧时间、燃烧室温度等。测试过程中，需要记录样品的燃烧时间、燃烧长度、燃烧速率等参数。

该标准的测试结果可以用于评估电缆和光纤电缆在火灾条件下的安全性能。如果样品在测试过程中燃烧时间、燃烧长度、燃烧速率等参数超过了标准规定的限制，那么该样品就不能通过该标准的测试。

IEC 60332-2-2:2004标准的实施可以帮助保障电缆和光纤电缆在火灾条件下的安全性能，减少火灾对人员和财产的损害。该标准已经被广泛应用于电力、通信、建筑等领域。
