标题: 请教UL对label的要求！
UL对贴在设备上的label要求过相关的规范，UL category code: PGDQ2 or PGJI2
请问如果是贴在镁铝合金上会有特别要求吗？
是否只要能在UL card上看到application surface有包含：Aluminum-magnesium alloy就可以？
除了对label material有要求外，对label的背胶是否也有要求？

当使用水或酒精去擦拭时, 不可有脱角或整个掉落产生, 其它是在字的定义, 楼主不需太怛心

樓主：
上次我們公司也專門對UL的標簽要求做過研究;
1. UL標簽的背膠及標簽印刷廠本身均要有UL認可
2. 這家UL印刷廠（而不是背膠生產商）的UL資料上“適合張貼材質”欄內要有鋁鎂合金項，且你們所使用標簽材質型號要與此項對應。
3. UL印刷廠的工廠檢查要合格，以往不合格的項目已全部CLOSE。
如果達到以上3條要求，應該不會有問題，不知你是否明白。謝謝

需要注意：标帖的材质要与申请认证时的一致，不同的标帖对应不同的外壳材料

2楼说的很详细了，补充一点，要特别注意印刷厂的UL category code是否相同。

回答非常正確﹐還有貼紙的溫度也有管控﹐即貼紙適用溫度在UL資料上會有體現

Yes, for Type R category, if label used, must be UL PGDQ2/PGJI2, you don't need to consider the adhesive, it should be considered by the label supplier....

Lable requirements for UL
-------------------------------------------------------------------------------------------------------------------------------------
Topic I--->Classification for UL type R markings
Basically, for UL type R category products, there are three kinds of UL marks which we can find in the market:
1. The UL listing mark: most of the UL final products can be covered in this kind of marking, such as the computer, PC, domestic appliance, power tools, and etc. For this kind of UL mark, it must be shown on the product itself;
2. The UL recognized mark: this kind of mark only applies to the components, not the whole products, and normally this kind of mark is "RU" with the "R" turns to the opposite direction. Not the same as the UL listing mark, this mark is not compulsory to be shown on the product itself or on the package, but in most cases, the manufacturer will show this mark on their products or the packages for those products;
3. The UL classified mark: this kind of mark is for some special products, and only some characteristics of those products can fulfill the UL's requirements, then it's not so common compared with the UL listing and recognized markings.
--------------------------------------------------------------------------------------------------------------------------------------
Topic II--->Decription and requirements for UL type R labels
Not similar with the UL type L labels, the manufacturers don't need to order and buy the UL labels directly from UL, at this time the manufacturers can print the labels by themselves or buy the labels from a UL authorized Label provider, so pls see below for details:
1. For UL listed/listing mark:
Normally, if this kind of mark is laser-printed or die-stamped, there is no special requirements for the labels,and at this time , the manufacturer only needs to send the design drawing of the label to UL label center and let the label center to review the design, then ok is ok.
But if the labels are adhesive paper label, then there are many requirements in most cases for the label provider:
1) The label provider must have the UL PGAA and PGJI2 or PGDQ2 program, that means there are two combinations for this kind of label

PGAA+PGDQ2)and (PGAA+PGJI2).
2) The label design drawing must be approved by UL label center, that means the manufacturer or the label provider must let the label design approved by UL before they apply the labels to their products.
3) If PGAA+PGJI2 is used, at this time, the label provider only provide blank or partial blank labels to the manufacturer, then the manufacturer can print some content on the labels by themselves, pay more attention that the ink or the ribbon which the manufacturer used must match the label materials, and this matching information can be found on the UL website.
2. For UL recognized mark:
Basically, in most cases,the "RU" in not the necessary element for this kind of products except the PWB, AWM. So for this kind of mark:
1) The PGAA program is not needed for the label provider.
2) The PGDQ2 or PGJI2 is needed and the requirements is similar with the listing mark.
3) Label design review is also not needed.

UL有时是外紧内松，还是有些漏洞的。只对资料不对材料。这点还是GS严点。

Who told you that? if as what you said, that only means the UL auditor who visited your factory is not responsible and professional.
Normally, the UL field representatives will check the compliance of the material, only if there is no real material or inventory during the audit, they will check the COC documents which can be traced, and this kind of traceability is also very complex....
