为什么不对比CL2.1来理解呢？
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.

6 d8 r. i5 f% c9 H) v; b6 t/ _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。
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。
