In the same example as per trail mail,
If the test coupon have failed in impact testing only & rest of tests (Tensile,Bend,hardness etc) have passed in a PQR (So WPS is qualified without impact test requirement), then is it required to redo all the mechanical testing (Tensile,Bend,hardness etc) along with impact test or only impact test to be carried out in next PQR to support the previously qualified WPS.
Thanks & Regards

Dear experts,--
Please help out to clear my doubt.
I have qualified a WPS/PQR with impact -29 deg C, now customer want the WPS/PQR shall be qualified with impact in -46 deg C. Also there is no remaining coupon piece available for impact testing with -46 deg C.
My question here is, should I weld a coupon and only do impact test as required by customer and attached to PQR will be sort out this issue.?
or
Should I REDO a PQR with all mechanical test which includes Tensile, Hardness, Bend along with impact will sort our this issue.?
Requesting you to please provide me ASME IX clause reference.
Anticipating for you kind help.
Thanks & Regards.
