46、 applicable. Duringthe first step, which is a test for ductility of the weld, except as allowed by 7.3.5, 7.3.6, and 7.3.7, no cracks or breaks on the insideor outside surface at the weld shall be present before the distance between the plates is less than two thirds of the specified outsidediameter

47、 of the pipe.As a second step, the flattening shall be continued as a test for ductility away from the weld. During the secondstep, except as allowed by 7.3.6 and 7.3.7, no cracks or breaks on the inside or outside surface away from the weld shall be presentbefore the distance between the plates is

48、less than one third of the specified outside diameter of the pipe but is not less than fivetimes the specified wall thickness of the pipe. During the third step, which is a test for soundness, the flattening shall be continueduntil the test specimen breaks or the opposite walls of the test specimen
