Hi Courtland, First some observations:
UL only grants rights to use UL marks. Other labs can test to UL standards, but they would grant their own marks. UL has Listed & Recognized Component & other certifications, but not "approval". In UL terms, Multiple Listing "ML" is where company X (Basic Listee) shares certification (but not control of the file) with company Y (Multiple Listee) & model numbers can be same or different between companies & there is an initial & annual fee. As an option to ML, many companies use what is called "File Number ID", where Basic Listee marks their UL File Number (E*****) on the product to identify them, and puts company Y's name/logo on the product also. If the model number must change, put the Basic model number out of the way & company Y's model # in bigger print prominently - no cost/no wait. If the Basic Listee wants to add an alternate model # (DEF) for marketing purposes, or for changes that do not affect safety, there would be a one-time cost (~U$600) for revising the Product Covered part of the report. I encourage my clients to use "wildcards" in their model number structure to allow for expansion without revising reports. Example: Today's new model is BELCHFIRE 2000 series. There are two versions which do affect safety & those will be identified by the 2nd character (2100, 2200). The remaining 3rd & 4th characters can be cosmetic & software versions, allowing many combinations without updating the report. The Product Covered would read: Model 2XYY, where X is 1 or 2 and Y is any number, letter, or blank. You can also say "may be followed by suffixes" to cover an infinite possibility. All above remarks apply only to UL. I hope this helps.
