Yesterday I’ve tested a PQR for my project. Every specimen passed its test except one side bend of all four side bends and two impact test of HAZ.
1.According to ASME IX paragraph QW-202.1 “If any test specimen required by QW-451 fails to meet the applicable acceptance criteria, the test coupon shall be considered as failed, and a new test coupon shall be welded.” Does it mean that I have to test again all of my passed two tensile tests and three side bend tests? Or, after welding of the new test coupon, I must test only another side bend specimen?
2.According to ASME VIII Div.1 UG-84(c)(6) “……when the value for one specimen is below the minimum value permitted for a single specimen, a retest of three additional specimens shall be made.” Does it mean a retest of three additional specimens for each failed specimen? In fact, do I have to test six impact specimens, three specimens for each of two failed specimens, as retest?
