Re: [MW:15196] Impact Test clarification

Dear Mubeen,
 
The impact test coupon can be run with same PQR and send to lab for testing at -46 Deg C.
This should be attached to the existing PQR.

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. 
M.K.Mubeen
