: Assemblies must undergo type tests and routine tests to verify performance criteria such as temperature rise limits and short-circuit withstand capability.
: The new standard clearly distinguishes between the Original Manufacturer (who performs design verification) and the Assembly Manufacturer (the panel builder who completes the assembly and performs routine verification).

If you are looking for current compliance or installation guides, note that is the modern standard. It replaces the TTA/PTTA concepts with a more rigorous "verified assembly" approach.
