- b. The use of motor operated valve diagnostic testing (e.g., stem strain measurement traces) to demonstrate valve functionality
- 3. Do current methods (and supporting data) for addressing the Part 21s ensure full stem thread engagement for the valves within scope of the Part 21s.
- 4. Are there other diagnostic tests or methods that can be used to demonstrate functionality for valves within the scope of the Part 21s?
