[問題求助] UL 2919可否不印VW-1？

請(qǐng)問我司UL認(rèn)證時(shí)，樣品的VW-1測(cè)試均不通過，那是不是代表我的線材都不能印VW-1？

但我看了"AWM  Style pages"，上面我看2919.。。。等style 均有要求印VW-1。

不知道可否真的不用印VW-1？

還有，像 STYLE 2725類的本身也沒有要求必須通過VW-1，那不會(huì)也不能用吧？

如果送樣認(rèn)証時(shí)VW-1沒過，到時(shí)線材上印字不能印，如果你對(duì)印VW-1無需求的話，那就沒關(guān)系了。具體的還需請(qǐng)教UL工程師。
