The new T/O program formalizes the “Test Only” process by providing National Board certification to organizations conducting in-service testing of pressure relief valves. The program includes an adjustment for restoring nameplate set pressure and provides customer and inspector confidence in testing capabilities. T/O Certificates of Authorization will be extended to current VR certificate holders. New applicants can obtain a T/O Certificate of Authorization by meeting program requirements.
