[Current]Non-destructive testing — Ultrasonic testing of carbon and low alloy steel forgings
Sets out methods for manual ultrasonic testing of carbon and low alloy steel forgings at three recording levels by the use of equivalent reflector sizes. Appendices provide information on probe selection, reflectivity diagrams, testing of curved surfaces, selection of beam angle and classification of discontinuities.
