引用第0楼EVERGREEN21于2010-10-15 09:52发表的 UL1082 Clause 2.2  什么意思？ :

为什么不对比CL2.1来理解呢？
, B# H' T, |8 j- ^9 f5 b2.1

Except as indicated in 2.2

, a component of a product covered by this Standard

shall comply with the requirements for that component

. See

Appendix A

for a list of standards covering components generally used in the products covered by this Standard.

9 p& u3 C4 w$ j) J! ~% y这些都是套话，说白了就是Appendix A类元件必须要有UL或CSA认证，除非你有2.2功能。但是2.2是要有工程判断才能确定是否满足。
