Dear, Impact testing should be carried out at MDMT temperature. If your Job required impact test on -29 than no need futher impact testing.

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.? ( Yes, you can test only Impact at minus 46C to add to present PQR by welding a separate test piece However you have to keep the all essential parameters same as the PQR qualified with Impact at minus 29C 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.
