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:
( V9 ~0 g3 M$ I4 s5 G! X" j/ w" y& n
X.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.

同时还应该注意标准的某些章节如UL1310:7 s- J! C1 M V7 O' Z

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:: e3 t R- D; n; c2 C' n
