AMS-P-81728 Updated

More plating spec news this week!  AMS-P-81728, “Plating, Tin-Lead (Electrodeposited),” has been updated and the new Revision B is available from Document Center Inc. now.  This new document replaces the previous Revision A from 2012, which is now obsolete and withdrawn.

AMS-P-81728 is the replacement specification for the old mil-spec MIL-P-81728, also titled “Plating, Tin-Lead (Electrodeposited).”  Cancelled in June 1998, the publication was immediately adopted and republished by SAE.  Since then, there have been 2 updates to the spec.

AMS-P-81728 B basically covers the requirements for electrodeposited tin-lead plating.  The intended applications for this type of plating are for use as a coating for corrosion protection and as a base for soldering.  Like the other two plating specs I’ve reviewed this week, it is one of our most popular documents for plating applications here at Document Center.

Many times the rationale for a new revision are complex.  In this case, Revision B was released for a simple reason:  When Revision A was released in 2012, the document dropped the Table 3.  This new Revision B puts it back into the specification!

However, for all of you using the AMS-P-81728, you will need a copy of the new edition.  And you’ll want to make sure that you get your copy from an authorized distributor.  Here, you can rely on Document Center Inc. to provide you with copies in either paper format or for pdf download.  It’s easy to order using our webstore, www.document-center.com.  Here’s the direct link for ordering the AMS-P-81728.

There’s a new AMS P 81728 Revision A on Plating, Tin-Lead (Electrodeposited)

SAE has just released the new Revision A for AMS P 81728, “Plating, Tin-Lead (Electrodeposited), ” and it’s available now from Document Center Inc.  This new 13-page revision covers the requirements for electrodeposited tin-lead plating intended for use as a coating for corrosion protection and as a base for soldering.

The document has a long and storied career.  It was originally released in 1969 as MIL-P-81728 with the same title as today.  The document was revised in 1973 and then cancelled and replaced by the AMS-P-81728 in 1998 as part of Mil Spec Reform.  The first AMS publication was a reprint of the original MIL-P-81728 Revision A with the amendment 1 changes included.  Now that Military Specification language has been revised.

The document illustrates how fundamental to many industries the old military standards and specifications were.  Even though they were originally generated to support DoD (Department of Defense) procurement, these publications came to be the standard throughout many U.S. industries, most notably the aerospace sector.  When the military decided that supporting a DoD-based specification bureaucracy was no longer fiscally sound, many of the documents went through a migration into the hands of industry based Standards Developing Organizations.

The continued vitality of a document like the AMS P 81728A is a sign that this migration has been successful in marrying the needs of both the commercial and defense sectors.

U.S. military and SAE standards are available from Document Center Inc. at our website, www.document-center.com.  Or consider contacting us by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).  We can provide you with these documents both in paper and pdf format, as well as monitor and audit your standards collections.  Our reporting services also assist many organizations maintain their collections for continued success with various compliance audits and reviews.
