PWHT hold time for PQR with Charpy impacts
PWHT hold time for PQR with Charpy impacts
(OP)
I understand the Section VIII-D1 rules for hold time of course, but I have a question concerning the following scenario:
(1) WPS was previously qualified without impacts, PWHT hold time 1 hour.
(2) Client wishes to augment the same WPS to add Charpy impact testing, PWHT hold time now 4 hours.
Q: Assuming the tests pass, is it valid to update the entire WPS to reflect 4 hours hold time, since initially it was a non-essential variable?

That answer presented itself to me as I wrote the question, but thanks for the confirmation.
