IEC 60950-1 4.7.3.4 Material for components and other parts inside fire enclosure有如下原文:
2 W5 [0 |' P5 W4 d9 d& q- electronic components, such as integrated circuit packages, optocoupler pakages, capacitors and other small parts that are mounted on the V-1 class material, [. c) @" ~0 M* Z, B1 d
这一项可以不要求材料的阻燃等级为V-2以上, 如此说来, 只要印制板是V-1的阻燃等级, 内部元器件的外壳的阻燃等级都不要求了吗?如果印制板上有直径16mm的塑料薄片,那么这个塑料薄片也没有阻燃等级的要求喽?

有点犯迷糊,有知道的帮忙解释一下?
