UL has two different services. Field Inspection<http://www.ul.com/global/eng/pages/offerings/services/globalfieldservices/fieldservices/fieldinspections/> is to look at equipment that has a Listing report, but left the factory without being UL marked. Field Inspection is done by an inspector who would normally do factory inspection, but does not have the engineering background to do a full evaluation. The inspector is only there to verify that the product matches an existing UL report. I used this service once when a number of air conditioners had to be shipped and installed while the UL Listing process was still in progress. The air conditioners had to go into the building on a certain schedule, and they were a new model still undergoing Listing. Once the Listing was done, the Field Inspection was done, the UL mark was applied and the AHJ was happy.
Field Evaluation<http://www.ul.com/global/eng/pages/offerings/services/globalfieldservices/fieldservices/fieldevaluationservices/> is done by a UL engineer who is evaluating a product to an existing UL standard. This is more common for equipment that is highly customized to an installation such as control panels, motor control centers, robotics and some heating and cooling equipment. There may be a limit on how long the equipment can be in place before the inspection, but it is typically done before the equipment is first used by the customer and would be done relatively soon after installation. UL, being the bureaucracy that they are, might steer you to the wrong program if you aren't careful in describing your needs. However, they do have both programs. It is likely the other NRTLs have similar programs with separate inspection/evaluation programs.
