UL电子线屏蔽率有无做明确规定
各位高手:UL对电子线屏蔽率有无做明确要求?
若有,具体规定在哪里?
谢谢! UL758標準內並沒有明確的要求。 有规定,请细看标准 在哪里做了规定,请告知。 Dear Mr Ma
For general AWM, it does not contain shielding coverage requirement.Please consider individual Style Page and your procedure to determine any specific shielding requirement.
For Flexible cord, the shielding requirement shall refer to UL 62, Clause 4.1.5, "The braided or wrapped shield shall provide a minimum coverage of 85% when calculated in
accordance with the method in Annex C." 看到Dear我就想到开不符合项的说明函,我觉得自己都有点神经质了 758 应该是没有要求的。 看到Dear我就想到开不符合项的说明函,我觉得自己都有点神经质了
关系搞好一点嘛,不能我们中国人吃亏,便宜了美国佬。

谢了,老NIU! 你屏蔽编多少,UL就给你定多少,然后写入档案,你就按此生产,UL认证很灵活,没有UL给你按你的产品定一个,不象3C很死板 你屏蔽编多少,UL就给你定多少,然后写入档案,你就按此生产,UL认证很灵活,没有UL给你按你的产品定一个,不象3C很死板
是这样么,我怎么没看到FACING PAGE有规定的?
