Robert and Group: Just one further clarification:
UL "Classification" means that UL has evaluated a product to a specific hazard (such as flame spread, smoke developed, slip resistance or sanitation) or the product has been evaluated to another organization's standard (such as an ASTM or ANSI standard).

All UL marked products have conditions of acceptability in some way, shape or form. 1. UL Listed mark goes on a product that is tested to a UL Safety Standard (or safety guidelines) for that product category and can be used as an entity unto itself (ie, a TV set). UL Listed products have conditions of acceptability defined by the product category (and written in conjunction with the product category Listing Cards and the standards/test guidelines tested against). 2. UL Recognition Mark goes on a product that is tested to a UL Safety Standard (or safety guidelines) for that product category and shall be used as a COMPONENT of a UL Listed product. An example of this is the plastics, tubes, internal wiring etc., of the TV set. UL Recognized products have conditions of acceptability tied into the exact component, based on the Listed product it will be placed in and its roll in the Listed product. The CofA's will be written on the Recognition Cards, or in some other manner (like Style Pages for AWM) for the specific product tested. 3. UL Classified Mark, in the past, could go only on previously UL Listed (and, possibly, on UL Recognized) products, and would cover classifications, ratings or conditions that the product was verified by UL above and/or beyond the safety issues of the product category. A product could be classified for non-safety performance, for instance (like Category 5 data cable is Classified for Cat 5 vs. IBM-initiated standards, and are also UL Listed as communications or power-limited data cable), or could be classiifed for additional safety standards for a specific use above and/or beyond the basic safety Listing. One should note that I believe UL has relaxed the past requirement that all Classified products must be Listed or Recognized first. I believe one could classify certain products without first testing for basic safety issues (perhaps product categories that do not have UL Standards for Safety testing but do have performance specifications to test and certify to). In summary, one could get a product that is UL Listed, Recognized and Classified, all at the same time. An example could be data cable. A cable could be UL Listed as Communications Plenum-rated Cable Type CMP (cable for communications run in air handling spaces in a building and sold as a building cabling solution), UL Recognized as AWM Style 2464 to interconnet between Listed Equipment (cable to interconnect UL Listed equipment, sold as a component to attach to a Listed product), and Classified as IBM Cat 5 cable for the computer industry (tested and certified by UL to meet all performance parameters specified by IBM for Category 5 cable). Where you use it and how you use determines what UL marks concern your inspector and installer. I hope this helps! Regards, Robert Tims Compliance/Test Engineer Ericsson Messaging Systems Inc.

A UL Listed product complies with all of the applicable requirements. Usually from a standard. 2. A UL Recognized Component does not comply with all of the applicable requirements. That is why they have Conditions of Acceptability. Whether the product is a complete unit or a component is immaterial to whether it is UL Listed or Recognized Component. If it meets all of the applicable requirements, it is Listed. If not, it is a Recognized Component. Now, sometimes UL cheats on this and calls it Classified. Medical equipment is Classified to UL 2601-1. This is mostly because UL does not require you to meet all of the requirements. They say the FDA (US Government agency) covers them.

UL also Lists COMPONENTS which an electrician might use in the field; for example closed-loop connectors, quick-disconnet connectors, splicing connectors, fixture wiring, circuit breakers, outlet boxes, etc. These components undergo more rigorous testing than normal components and are always provided with installation instructions limiting the usage; for example a splicing connector may specify the exact crimping tool and the # and size of all the combination of wires to be spliced by that connector.
