復(fù)雜的很啊
18
這個簡單啊,直接看UL758標(biāo)準(zhǔn)和UL1581標(biāo)準(zhǔn)知道了呀!
Style PAGE 這個是一個總體的標(biāo)準(zhǔn),是做線的線材標(biāo)準(zhǔn),也就是各條線的UL要求.我說的UL758標(biāo)準(zhǔn)和UL1581這兩個標(biāo)準(zhǔn)是專講線材的各項(xiàng)測試要求和講解怎么測試的.
19
專家碰上專家,一定會冒火花。
20
每種線材都須符合一種燃燒要求,如線材上印上VW-1,那就必須符合VW-1燃燒標(biāo)準(zhǔn)(測試項(xiàng)目方法請參照UL758&UL1581),相反的,如果不能符合VW-1燃燒標(biāo)準(zhǔn),那就不能印,關(guān)鍵是看公司或客戶要求線材須符合哪種燃燒要求。
21
22
線材進(jìn)行UL認(rèn)証時是要進(jìn)行阻燃檢測授權(quán)
23
現(xiàn)在最新的UL標(biāo)準(zhǔn)都改成不需要過VW-1,只要過水平就好!可以不用那么嚴(yán)格來控制了!
24
線材印字的燃燒等線要看你當(dāng)初申請ul認(rèn)證時所發(fā)的ul細(xì)則,已明確規(guī)定.
25
現(xiàn)在的 ul style page 真的 讓人無所適從了. 我們今年五月份認(rèn)證下來的 無鹵部分 比如 20844 21088 21099 21451 這些style page 里面 新版的 沒有要求 flame 等級. 而認(rèn)證 資料里面 給了一個 vw-1 沒有 授權(quán). rating : vw-1 flame rating not authorzed .
我做印字輪 該怎樣選 flame 等級呢.
</FORM>26
誰知道UL 3499 絕緣材料有什么要求?
27

那就不可以放VW-1了!你的成品只需要測Horinzontal Flame Test
你試試看UL Style Page的 Rating那邊該有沒有燃燒等級

做電線的:
具體對應(yīng)的規(guī)范是哪個?下面為我在UL網(wǎng)站上看到的關(guān)于AWM20276的一份Stlye PAGE
但是并沒有看到要求,所以還是有點(diǎn)迷茫。。。。

RATING那邊有指明
29
在ul758中,你們ul認(rèn)證時所發(fā)的細(xì)則有明確的規(guī)定,你按照細(xì)則上要求即是,
如果沒有,它上面也會寫vw-1沒許可,即不能印vw-1字樣,哪只要通過水平測試即可,
FT1 , FT2 是C(UL)即CAS加拿大標(biāo)準(zhǔn).

31
學(xué)習(xí)啦
32
學(xué)習(xí)了!
33
依當(dāng)初公司所申請的標(biāo)準(zhǔn)來測

UL20276 style page 變成這樣的了...
落后的很....
37
做電線的:
是的,呵呵,謝謝了,仔細(xì)看了下,確實(shí)是最基本的要求的測試都在上面了。。。。
還有上面對應(yīng)的section對應(yīng)的是1581的么?
還有一個就是比如說20276的那樣子的AWM,對絕緣料沒有要求的,這個時候應(yīng)該根據(jù)
什么樣子的規(guī)范或者要求來選擇呢[做電線的 在 2009-4-16 14:13:53 編輯過][/blockquot]
對應(yīng)的就是758里的章節(jié)啊 比如 : section 7 就是指第七章
