We strongly recommend performance testing to insure any differences between the two TCO sources do not exceed safe limits. This should apply, as well, to products from the same supplier who has undergone a part number alteration or made a manufacturing location move. Satisfactory continued listing of the TCO by the various agencies does not necessarily assure identical performance in an application.
