MIL-F-13926 comes “back to life” with the new Reactivation Notice 1

MIL-F-13926 Revision B, “Fire Control Materiel, Manufacture and Inspection, General Specification For,” has been brought back from “limbo” with the release of the new Reactivation Notice 2, replacing the Inactivation Notice 1 from 1995.  The specification covers the general requirements for the procurement, manufacture and inspection of systems, components and assemblies used in fire control material.  It is available now from Document Center Inc. in both paper and pdf format.

The Inactivation Notice 1 from February 1995 made the specification inactive for new design so that it should have only been used for replacement purposes (repairing or supporting existing applications).  However, with the release of the new Reactivation Notice 2 on June 5, 2012, MIL-F-13926B may be used for either new or existing design acquisition.  By the way, the MIL-F-13926 replaced the cancelled MIL-STD-1242, “Machining Standards for Fire Control Material,” back in 1984.

At Document Center Inc., we continue to monitor customer purchases even when the documents have been inactivated or cancelled.  The reason why is that you can never tell when a document that the caretaker thinks is obsolete may be actually widely used by the supporting vendor base.  This disparity sometimes results in the caretaker reevaluating the rationale for supporting the technology for the sake of the user base.  To miss this type of transition could be as harmful to your business as missing a new revision level release.

You can purchase military specifications and standards like the MIL-F-13926 from 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).  Our new edition of our website is nearing completion and we’re looking forward to your comments when we bring it online in July!

MIL-M-38510 J on Microcircuits recently validated

MIL-M-38510 Revision J, titled “Microcircuits, General Specification for,” was validated on 6/29/2011 with the release of Validation Notice 3.  The notice confirms that MIL-M-38510, Revision J with Amendment 1, is still valid for procurement by the U.S. Department of Defense.

The notice also reaffirms that the specification is inactive for new design.  This means that it can only be used for replacement (replenishment) purposes.

MIL-M-38510J establishes the general requirements for monolithic, multichip, and hybrid microcircuits.  It defines the quality and reliability assurance requirements which must be met in the acquisition of microcircuits.  Detail requirements, specific characteristics of microcircuits, and other details of microcircuits that are specific to particular uses are all addressed in what are called slash sheets.

The previous validation notice, Notice 2, released in March of 2001, defined the documents that should be used in lieu of MIL-M-38510 for new design.  The bulk of the specification is covered by MIL-PRF-38535.  However, some topics are addressed by MIL-STD-1835, MIL-HDBK-780 and MIL-HDBK-983, which has since been canceled without replacement.

FYI, a review of standards is often set to a regular schedule, such as the five year cycle set by ANSI, the American National Standards Institute.  When a review confirms that the document is still good without any further changes, a validation, reaffirmation, or reapproval notice may be issued.  It may be released as a stand-alone document, as with the DoD validation notices, or as a reprint with the reapproval date included, or just as a notation on a website or catalog.  When this occurs, the actual content of the document is unchanged.

MIL-M-38510, and all publicly available Military Specifications and Standards, can be purchased from Document Center Inc. at our website www.document-center.com.  You will get free update notification of all future changes to any purchases via our email notification service.  This means that you will always know when any standard you purchase from Document Center Inc. changes.  Get more information by phone (650-591-7600), fax (650-591-7617) or email (info@document-center.com).
