What ever happened to MIL-STD-2154?

What ever happened to MIL-STD-2154, Inspection, Ultrasonic, Wrought Metals, Process for?  Actually, the standard was picked up by SAE International.  It was renumbered AMS-STD-2154 and has been an active standard ever since.  Since the AMS-STD-2154 has just been updated to a new Revision C, let’s take a look at the history.

MIL-STD-2154 was an important metals standard provided for defining uniform methods for ultrasonic examination of wrought metals and wrought metal products.  It was originally released in 1982.  The transition from the MIL-STD-2154 to the AMS-STD-2154 has been a rocky one.  Here’s what happened:

SAE first published the AMS-STD-2154 in 1998.  It was identical to the original MIL-STD-2154 from 1992.  However,  the MIL-STD-2154 was only withdrawn by the DoD in 2004.  So for a while the two standards lived concurrently.  This was a confusing situation that occurred more than once.  Industry associations assumed that certain military publications were going to be cancelled.  In response, they developed identical industry documents.  However, for what ever reason, cancellation of the military spec or standard didn’t happen.

Since the original MIL-STD-2154 Cancellation Notice in 2004, there have been an additional 2 cancellations.  The Notice 2 was released in 2008 and the Notice 3 was released in 2009.  Cancellation Notice 2 directed Military procurement officers to use the ASTM-E2375 instead of the AMS-STD-2154.  The Cancellation Notice 3 allows for the use of both the AMS and ASTM documents.

In the meantime, the AMS-STD-2154 has been undergoing changes.  Revision A was released in 2012 and Revision B in February of 2017.  However, there were errors in Revision B and SAE International retracted the update.  Now, with the release of Revision C, the document has been corrected.

What was the problem?  Some of the paragraphs in Revision B were mis-numbered.  Since Revision C is the correct update, changes from Revision A are still noted with the black lines in the margins.  This will help you identify areas where revisions may impact your processes.

Another thing to note is that the AMS-STD-2154 replaces not only the MIL-STD-2154 but also the MIL-I-8950.  So you can see that the publication has become a staple for this type of ultrasonic inspection.

New AMS STD 2154 Revision A released for Inspection, Ultrasonic, Wrought Metals, Process For

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.
