This specification covers ultrasonic angle-beam procedure and acceptance standards for the detection of internal discontinuities not laminar in nature and of surface imperfections in a steel plate. This specification is intended for use only as a supplement to specifications which provide straight-beam ultrasonic examination. The ultrasonic frequency for the examination shall be the highest frequency that permits detection of the required calibration notch.
