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:" b* `! y9 \$ q7 w' C7 a k8 Z2 G

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.
