那个帖子对LZ没有用.请LZ参考一下你们报告的Section General,那里有规定.9 r- C' W* s, _9 C9 }
什么算Part?就是组装以后带的Fitting,没有绝对的分类,要具体的东西才能分别.常用的如一个housing,线挡,USB头等都是属于parts.要看看你的出货时候产品包含的总数.0 i% \" h$ b0 Z* D
FORM 1-N: This Recognition Mark is used for harnesses consisting of four parts or less. Each piece of wire, fitting, splice, terminal block, wiring device, etc. is considered to be a part. Simple terminations of the eyelet, ring, open spade or quick-connect types are not counted as a part when determining the form label to be used. One of the four (or less) parts may be a Listed power supply cord.0 R; c- T' _/ q2 P) M1 H4 |

以上建议LZ只要明白前两种就行了,后面两种很少遇见.而且从目前市场来看,绝大部分都是属于FORM 1-T,至少占90%. 即使遇见了后面的产品到时再问问UL工程师帮忙判断一下即可.我想讲到这里应该没有什么混淆的.至少工作中够用了.本草民认为,知识学习到够用就行.什么都要搞到不明白透彻不罢休的话,很容易陷入技术固执派. |
