Markings ofUL

The UL Listing Mark is one of the most common ULMarks. This type of Mark is seen commonly onappliances and computer equipment, furnaces andheaters, fuses, electrical panel boards, smoke and

carbon monoxide alarms, fire extinguishers andsprinkler systems, personal flotation devices, bulletresistant glass, and thousands of other products.

These are Marks consumers rarely see becausethey are specifically used on component parts thatare part of a larger product or system. Thecomponent recognition marking is found on a widerange of products, including some switches, power

supplies, printed wiring boards, some kinds ofindustrial control equipment and thousands ofother products.

Markings ofUL

A UL Classification is given to productiongrade products which have been tested andevaluated with respect to certain properties ofthe product. Having a UL Classification means

that UL will conduct unscheduled factoryfollow-up visits to verify that these productscontinue to meet the applicable requirement.

Markings ofUL

How does a Classification differ from a Listing?

The Listing service applies to products investigated by

UL for reasonably foreseeable hazards and is usuallyfound on consumer products. UL Classification service

is a more extensive evaluation. Under this service, ULevaluates products with respect to certain hazards,limitations or safety conditions of performance.Classification service is primarily for the guidance of

inspection authorities, commercial and industrial users,and is generally notapplicable to consumer products.
