Dear 余澤平
Thank you for your questions.
I would like to reply as below.
1. Please be noted that the aging requirement (48 hrs, 100C) in UL 1581, table 50.136 shall be used for the PE material with 75C temperature rating. Since your selected sample provided with 80C temperature rating, the aging requirement shall be 7 days, 113C per UL 758, Sec. 7.2.5.
2. We would update the information accordingly.
If you have any question, please feel free to contact me.
Best Regards
Dan Chan

以上是我提出質(zhì)疑時,UL給我的回復
總結(jié)一下就是:
里面的芯線用的是UL1589 PE絕緣
如果線材印字為80C額定溫度,其老化條件則參考UL758 7.2.5部分:7days 113C
而線材印字為75C,或以下(60C),其老化條件則參考UL1581 50.136部分:2days 100C
我再提出質(zhì)疑說80與75C也只相差5C,怎么會有相差這么大的測試條件
他們答曰:叫我去向美國那邊申請修改文件,他們只能按文件作業(yè)
不知各位朋友有沒有遇到以上類似狀況,并予以討論
