Material with discontinuities indicated by the testing unit is permitted to be reexamined or retested, atthe option of the manufacturer, to determine whether the discontinuity is cause for rejection. Signals that are found to have beencaused by minor mechanical damage, soil or moisture shall not be cause for rejection of the material provided the dimensions ofthe material are still within prescribed limits and the material is suitable for its intended application.10.3 Hydrostatic TestWhen specified, the material shall stand, without showi
