This Directory contains the names of companies authorized to use the UL Recognized Component Mark on or in connection with components that have been investigated by UL and found to be in compliance with UL’s requirements. These companies, as well as the manufacturers and submitters of the components, have entered into an Agreement with UL to use the UL Recognized Component Marking only on or in connection with components manufactured in compliance with UL’s requirements. It should be noted that the Recognized Components of different makes or model designations are not necessarily equivalent in quality or performance. For information concerning Plastics Recognized Components, refer to UL’s Plastics Recognized Component Directory. UL investigations of products or equipment for the UL Listing/Classification Mark generally include an evaluation of the suitability of components (i.e. relays, switches, plastics, etc.) for use in the specific end-product. Recognized Components are intended for factory installation in end-products or equipment where the limitations of use are known to the end-product manufacturer and where their use is within such limitations as evaluated by UL. The conditions of acceptability of the Recognized Component need to be compatible with the specific end-product application. Since these components may be incomplete in construction and/or restricted in performance capabilities, they are not certified by UL for use as field-installed components. UL’s Component Recognition Service evaluates components by establishing performance requirements and/or construction requirements for use in specific end-product applications. The appearance of catalog or model numbers or other specific component designations in this Directory signifies that: (1) representative samples of these components have been submitted to UL and found to comply with the applicable requirements, and that (2) the manufacturer has been authorized to use the Recognized Component Marking on production that continues to comply with UL’s requirements and is subject to UL’s Follow-Up Service. Since manufacturers are not obligated to apply the UL Mark on all of their production, components that do not bear the UL Recognized Component Marking are not required by UL to comply with UL’s requirements. The manufacturer’s products are not subject to UL’s Follow-Up Service unless they bear the UL Recognized Component Marking. Only those components bearing the appropriate UL Recognized Component Marking should be considered as being covered by UL’s Recognition and Follow-Up Service. The Recognized Component Directory is intended to assist manufacturers who may wish to use a Recognized Component in their end products. For some components, part or all of the use conditions and ratings are indicated in the Component Category Guide Information and the individual Recognitions. Information and limitations on the component can be obtained by contacting the component manufacturer at the address specified for the individual Recognition in the Directory. This Directory contains Recognitions in effect as of February 15, 2008. Records of Recognitions issued or withdrawn after this date will be found in UL’s Listing Information database. In addition, Recognitions issued after the effective date will be found in UL’s Online Certifications Directory at www.ul.com/ database and will appear in the next annual printed Directory. Users of this Directory are urged to read carefully the following sections for an understanding of the extent of UL’s services.
