请问我司UL认证时，样品的VW-1测试均不通过，那是不是代表我的线材都不能印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？

样品送UL测试时，其中任何一项没有通过都不能申请到UL证书，而不是能不能印“VW-1”的问题。

不会吧！ 那为什么UL通知我要来我司做IPI呢？

还有，像 STYLE 2725类的本身也没有要求必须通过VW-1，那不会也不能用吧？

style pages 中都要求了，肯定要过才可以了，不能过就不要做这个型号了，免得到时候罚你的钱。

如果送樣認証時VW-1沒過，到時線材上印字不能印，如果你對印VW-1無需求的話，那就沒關系了。具體的還需請教UL工程師。
