引用第0楼EVERGREEN21于2010-10-15 09:52发表的 UL1082 Clause 2.2  什么意思？ :
2.2 A component is not required to comply with a specific requirement that:

% T* [9 h5 F& B% E

' X: ?* y& p( S: x- D+ B  b! m为什么不对比CL2.1来理解呢？
; w5 c4 U* U8 }6 w% K, \2.1

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.

也就是说有2.2所列功能，就不用满足2.1要求。2.1就是specific requirement 。2.1要求是什么？参照Appendix A。
3 U& p$ d5 h! [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。
