可一参考UL758做芯线老化的

楼主:问你的原材料供应商,2464线材内芯线的安规型号,依安规型号做。

是的,芯线UL公司是不做的,客户有另要求外!

如果只做2464,芯线是不要求的。但是在生产后,UL跟踪服务会考察你的芯线,必须是通过了UL认证的芯线。比如您自己的认证过的线或者使用别的厂家的UL认证芯线即可。

这个就是UL抽样所检测的所有项目与频次了,没有提到检查芯线的老化性能。
但是理论上讲所有的性能都要合格,才能称为合格的产品。只是应付检查,达到以上6条要求就够了

应该是要做的, 芯线可以是类似1061 或 1007 类的电子线, 送样的话最好是用类1007的电子线, 1061很难过的.
