多芯線如何做燃燒VW-1(只做外被嗎,那么多芯線絕緣層也需要做嗎)?
哪份標(biāo)準(zhǔn),第幾章節(jié)有規(guī)定,謝謝

UL758
41.2Insulated conductors in a finished cable are not determined to be rated VW-1 unless specically noted on the tag marking.就是說除非在標(biāo)簽上有特殊標(biāo)識說明芯線燃燒等級是VW-1,其它情況護(hù)套線中的芯線是可以不通過VW-1的。

請看一下那款多芯線是屬于UL 里的哪種類型線,如AWM 中各STYLE NO的STYLE PAGE中有要求需做哪種燃燒測試。
