期待高手，我一致以为UL是瞎编的

对于电源产品:
1. 只要能通过测试, 那种Fuse都可以使用;
2 K4 V" v4 `7 a+ c) G2和 3, 这两种分类的保险管分别为JDYX是UL List 的, JDTX2 是UL Recognise, 使用JDYX做完认证后, 可以使用JDYX2的替换(但需要报备, 还要加做相关测试,OK后才能使用), 使用JDYX2做完认证后, 可以使用JDYX的替换(也需要报备, 但不需要再进行测试, 如果相同技术参数).

UL Recognise和UL List 是如何定义的？
两者之间有多大程度的区别？

具体的差异，你可以点开UL网站CCN查看具体差异，不过说实话绝大多数时候说的都不是太清楚。

简单的说就是recognise就是有条件的认可，最终产品需要根据认可的应用条件选择符合自己应用的recognise的元件。

说实话这些东西都非常的模糊，很多时候，很多厂家都是被这些东西开了VN

- Z0 r8 f5 W* _, m, rA: Normally, the CCN is composed by four letters and one number, and the CCN is defined by UL, so for difference between those CCNs, you must see its explaination and its related products standards,if applicable, but here, I'm saying:
XXXX/XXXX7: this kind of CCN is for the UL listing products, and XXXX is for US, XXXX7 is for Canada, all this kind of products must have the UL listing mark("UL" with a circle around it) attached;
XXXX2/XXXX8:this kind of CCN is for UL recognized components, and XXXX2 is for US, XXXX8 is for Canada, all this kind of components may have the UL recognized mark("RU") attached, but this RU mark is not a necessary element for UL, sometimes, it can be ingnored;
XXXX3/XXXX9: this kind of CCN is for some UL XP file, like the attachment and plugs file for the power cords' file, it's not so common.

Frankly speaking, most of this kind of issues are very clear, why VN was issued about this kind of things, the reasons are as below:
1. The manufacturer representatives are not so familiar with their products' standards, then they didn't pay more attention to this kind of issues, then VN happens;
2. Even if the manufacturers representatives are familiar with the standards, but they didnot supervise this kind of issues, then change without notification to UL happens and VN also happens as results.

so as a UL manufacturer representative , you must :
! X4 y, \1 }0 ?: K1. Be familiar with your products' standards;
2. Check your own products at intervals, and make sure that there is no change on your products and can comply with the FUS procedure's description;
2 A" r9 o# v  e3. If products' change happens finally, then you can judge whether this kind of change needs the UL engineers' reevaluation or some additional tests or only the paper work needed.
