UL自己出的每一个标准都会几乎都有这么一个章节或类似的章节:6 h" _9 X2 n! F( b6 O
\8 I, r3 B& UX.1 Except as indicated in 4X.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.- ^. M" E: j* V. M( T' D# e9 H$ w

同时还应该注意标准的某些章节如UL1310:
4 q& x7 ~$ L+ B
$ f3 {* ?& }8 O( L12.2 There shall be no components connected between primary and output circuits which result in a conductive connection (see 5.4). If capacitive coupling is provided between primary and output circuits, it shall consist of either:

' w% q: q5 m* _. f/ l. I5 A, W; ?. ^
现在UL的一些标准也在做改进,如UL499则开始抛弃Appendix A的传统要求,开始细化到具体要求如:# h9 F. ?1 B' b- Q4 j

可以看出,其实UL标准对于零部件的具体要求是非常明确的。
