SAE International has released a new AMS STD 2154A, “Inspection, Ultrasonic, Wrought Metals, Process For,” and it’s available now in paper or pdf format from Document Center Inc. The purpose of this standard is to provide uniform methods for the ultrasonic inspection of wrought metals and wrought metal products.
The new Revision A makes the following changes:
- revises personnel qualification (Section 4.2),
- adds requirements to the list of written procedures (Section 4.3),
- revises reference standards (Sections 5.1.2 and 5.3.1.2),
- adds surface texture requirements (Sections 5.4.6 and 5.4.7),
- permits adjustment of sensitivity if the required sensitivity standard hole is not available (Section 5.4.8),
- adds direction on setting the primary reference response (Section 5.4.9.1) and establishing electronic distance/amplitude correction and time-corrected gain (Sections 5.4.10 and 5.4.10.1),
- revises electronic equipment requirements (Table 2),
- revises ultrasonic class requirements (Table 6),
- and updates referenced standards.
The original AMS STD 2154 is the adoption by SAE of the MIL-STD-2154. The new Revision A updates that original text and is the correct replacement for the now obsolete MIL Standard. This document also supersedes MIL-I-8950 (same title, last valid edition was Revision B), which was cancelled in 1983 and replaced by the MIL-STD-2154 at that time.
