UL R 類產品與 L 類產品的差異
UL 產品中 分為R type 與L type兩種想請問板上面的高手, 這兩種分類的差別在哪裡?
因為小弟我曾經接觸過UL Report
該產品所做的標準為UL 1838戶外風景燈 總共有三十多個型號
在看元件描述的部份, 只有寫出一個型號當代表,
外殼(enclosure)也只是粗略的描述.
但我看所有型號的外觀時, 發覺外殼尺寸差異很大,
但UL報告只控制一個型號, 難道沒有溫度安全上的考量嗎?
後來我問了一下我學長, 他說因為是該產品是 L Type的關係,
許多的評估與測試都會移到工檢端檢查, 所以報告
部份比較不會描述這麼詳盡.
但到UL網站上, 仍沒對R type與L type 產品有詳細的描述
想請板上大大解惑 哪位帮忙回答一下a29635138 的问题？？？ 一般来说, L (Listed) 是成品(product), R (Recognized) 是部件(component) 但楼主说的问题似乎与 R 或 L 没有关系!
UL一般会选择整个系列中最具代表性之型号作测试，但会把所有型号描述在报告上！
楼主的情况就不太明白！ 小弟感謝H-RH的說明
可否再請教另一個問題
如果是L type 是 Listed 成品 而R type 是Recognized部件
那工檢(Follow-up Test)的流程是否有所差異呢? L type 是 Listed 成品R type 是Recognized部件
具体厂检流程都是一样的 引用第5楼bujust于2011-06-21 15:41发表的:

同意楼上说法! 感謝前輩們的指教~~~ You can understand them in an easy way, normally:
1. R category product is some kind of Regular products, it also can cover both UL listed and recognized products, and normally for this kind of products, the inspection frequency is 4 times per year, anyway, there are some special cases, for example, plastics(QMMFZ2), if all required samples are available during one time inspection, then once per year is enough;
2. L category product is this kind of UL products which must use UL labels(released by UL directly), for example, wire and cable(UL758/UL62/UL764/UL817), lamps(UL153/UL1598), for this kind of products, the inspection frequency depends on the output of the products. 引用第2楼H-RH于2011-06-20 15:35发表的:
一般来说, L (Listed) 是成品(product), R (Recognized) 是部件(component)
What you mentioned "R" and "L" is totally differenct from what the poster wants to know.
And what you said "R" and "L" is the recognized marking and listing marking, but what the poster wants to know is the R category and L category UL approved products.
