UL mark and use
The use of UL's column name, rating, and approval mark on or in relation to a product is the only method UL specifies to distinguish products manufactured under UL's tracking inspection service. The presence of a company's name in the UL catalog does not mean that the company's products are UL listed, rated or approved. Only those products bearing the UL mark are considered to be products manufactured under the UL tracking inspection service.
According to the different service types of UL, UL mark can be divided into three categories, namely column name, classification and approval mark. The most important part of these marks is UL pattern symbol, which is the registered trademark of UL. Three symbols are used for three different services on the product, can not be mixed, otherwise it can be considered as counterfeit products. Because classification mark is relatively rare in our country, so the following only introduces column name and recognition of two marks. UL's services are based not only on the American UL standard, but also on the Canadian standard (c-ul). Thus, UL marks are also used for UL products and c-ul products and both meet three requirements.
Note: for products listed or approved as UL and c-ul, the UL and c-ul labels may be applied at the same time until January 2008, but by 2008 the third column in the above table must be used.
The "inspection instructions" state which mark you are permitted to use and where the mark should be placed on the product. This mark may only be used if the manufacturer complies with the terms of the "inspection specification" and the "follow-up inspection service agreement". (para. 2) the UL mark shall not be used in any way on the product or package unless you are permitted by the inspection instructions. (para. 3).
If your product is under one of UL's services and meets UL's requirements, UL will allow you to quote UL's logo and U's name in your promotional or promotional advertisements, but such reference must not create an inaccurate impression to the public. A simple quote saying that the product is "ListedByUL" or "RecognizedByUL", or the pattern of UL logo, is appropriate, depending on the category of service it belongs to; The words and phrases of the product marks you use shall correspond to those stated in the "inspection instructions". When your product belongs to UL's classification service, references to UL in your advertisement must quote the full text of the entire product classification mark, as stated in the "specifications of inspection". Since UL may ask you to change inappropriate parts of your promotional or promotional advertisements, it is best to contact your UL inspection representative in advance to inform him of the manner in which you intend to quote the UL logo or name. This avoids misunderstandings, as well as the waste of retracting publicity and promotional advertising that UL deems inappropriate.
