S12.3 If one specimen fails (“Breaks”) on any plate tested, retests may be made as follows:
a. Retest two additional specimens from each plate for which a specimen failed. [ach of these two retest specimens must pass (“No Break”).
h. If any of the specimens fail upon retest. the heat shall not be accepted without reheat treatment and repealing the tensile. Charpy V-notch impact. and drop-weight tests.
S13 Surface Quality
For applications where surface quality is considered critical, plates are to he furnished in the blasted and inspected conditions. The depth of rolled-in scale or clusters of pits shall not exceed 0.015 in. (0.381 miii) and shall not result in an undergage condition. However. isolated individual pits not over 0.030 in. (0.762 mm) deep are acceptable provided that the plate thickness is not reduced below the specified minimum. Other surface imperfections such as tears, seams, snakes, blisters, scabs, etc. are not acceptable and must be conditioned without reducing the thickness below minimum. The surface imperfections may he removed by grinding provided each gmwd area is well faired and grinding does not reduce the thickness of the plate below minimum.
S14 Thickness Tolerance
By agreement between purchaser and supplier, plates shall be furnished to 112 standard over tolerance for thickness shown in ASThI A6/A6M,
