Can UL offer a reduced testing plan if we want to move an existing ITE certification that was investigated to UL/EN/IEC 60950-1 to the new UL/EN/IEC 62368-1?
It appears the question is asking on the feasibility of using existing 60950-1 test data in a transition to 62368-1 to reduce testing. Unfortunately, this sort of question cannot be addressed in depth in this sort of forum since the answer is mostly dependent on the product type (construction, function, complexity, components involved, etc.) and resulting application of the Standard. However, we need to keep in mind that 62368-1 is not a merger of 60065 and 60950-1, and is considered a new standard. Therefore, there are many new requirements and tests that were not in 60065 and/or 60950-1. Also of importance is to realize that even tests and requirements that have been carried over from the legacy standards, in most cases, have been changed to some degree, impacting potential validity of previous test data. From a certification engineering perspective, experience is demonstrating, analyzing existing data for validity (engineering analysis at a cost) could potentially take more time/effort than conducting a fresh set of 62368-1 tests.
