Annotation of standard text ASTM A745/A745M-24 :
This test method deals with the procedures for the standard practice of performing contact, pulse-echo ultrasonic examination of austenitic steel forgings by the straight and angle beam techniques. This practice does not cover the ultrasonic examination of nonmagnetic retaining ring forgings. The instrument used for this test method shall be the electronic pulsed reflection type. Prior to examination, specimens shall be heat treated and machined to a rectangular, parallel, or concentric surface configuration, and its surface shall be free of extraneous material such as loose scale, paint, and dirt. Calibration of the apparatus shall be done by either the single-block method or distance-amplitude curve method. Choice of method to be employed shall be determined by the test metal distance involved. Quality levels for acceptance, established by the type and amount of indication present, are detailed thoroughly.
