UL logo is recognized in the United States as well as North America security certification mark, affixed with such signs of products, it is equivalent to access to a safety quality credit card, its reputation has been accepted by the vast number of consumers. Therefore, the UL logo has become a special pass for products (especially electromechanical products) to enter the United States and the North American market.
UL marks are divided into 3 categories, namely column name, classification and approval mark. The main components of these signs are the patterns of UL, and all of them are registered trademarks. It is not common to apply them to different service products.
Column name
UL's column name sign on the product indicates that the sample of the entire product of the manufacturer has been tested by the UL and complies with applicable UL requirements.
Classification
Products with this mark, whose dangerous limits or scope of use have been assessed.
* meta / component authentication
In order to accelerate the speed of evaluation of product or system, and save money for the component or incomplete performance limiting, for UL column or classification of product or system products, can be yuan / component certification. Using UL - Certified components in any final product does not mean that the product itself is a product of the UL column name.

The character representation of different product categories in UL column names, approval, and classification services. For example, AVLV2 stands for electronic wires; QOWZ stands for portable lamps. In general, XXXX is the name of the product, XXXX2 is the approved product, XXXX7 represents the Canadian listed product, and XXXX8 represents the approved product complying with Canadian standards.
COMPONENT (parts)
A part of a product that needs to be tested separately for its performance and / or structure in addition to being part of the overall product. Parts may be column names, recognized or non - listed components.
CONDITION OF ACCEPTABILITY (applicable condition)
These items are listed in the reports of approved or non listed components, but not as the basis for inspection by site representatives. These projects are based on test results that indicate the limits and conditions for the parts to be used with the finished product. For example, in a report of a switch, it may be indicated in the "applicable conditions" that the product applies only to currents below 1A or below 125C.
CONTROL NUMBER (control number)
UL identifies one of the four possible components of the mark, specified by UL. The control number may vary periodically depending on the product category and the type of tracking service.
FACTORY IDENTIFICATION (factory logo)
An identification mark used by a manufacturer who produces the same product in different factories to distinguish which plant is produced at which plant.
FACTORY INSPECTION (factory inspection)

AP: 4.UL1449 UL on Surge Testing of safety regulations.
AP: 5.UL1459 UL of communication products, testing of safety regulations.
AP: 6.UL1778 UL of the UPS system to test the safety regulations.
AP 7.UL1950: safety regulations generally, mainly for electronic products and electronic device to test the safety regulations.
AP: 8.UL478 UL on computer equipment to test the safety regulations, the regulations is to replace the 1992 release of UL1950.
AP: 9.UL497A inhibition test for UL device safety regulations on phone surge.
