AMSSTD2154E Inspection, Ultrasonic, Wrought Metals, Process for

AMS-STD-2154D revises standard test block inspection (5.1.2.1), reference standards (5.3), distance-amplitude correction (5.4.10), evaluation of discontinuities (5.4.16), and Table 2, Note 4.

AMS-STD-2154E includes revision to transducer size (5.2.4), adds (5.4.15.1) exceptions to the transfer technique, allows a type 1 option (5.1.1.2), deletes noise note in Table 6, and adds notes of explanation for Figure 12. Because this revision clarifies changes from revision D, changes for both revisions are maintained.
