MIL-STD-981 C Updated – Electromagnetic Devices for Space!

MIL-STD-981 C, “Design, Manufacturing and Quality Standards for Custom Electromagnetic Devices for Space Applications,” has been updated with the release of Revision C interfiled with Notices 1 and 2.  The standard is the technical baseline for custom electromagnetic devices for space applications.  These include such products as transformers, inductors, coils, charging inductors, and the like.  They are used in critical space applications, mission-essential ground equipment, and also in noncritical flight and ground support applications as well.

The 68-page standard was released as the Revision C back in 2010 with 1 other round of updates occuring when Notice 1 was issued in 2014.  When Change Notices like this are used, the updates are usually not extensive and this is certainly true with the recent release of Change Notice 2.  For the user’s convenience, black lines in the margin are used to point out the areas in the standard when updates have been made.  That is the case in this consolidated release.

You’ll find the margin alerts for MIL-STD-981 C’s Notice 2 in the following areas:

  • Clause 5.5.12.8 on Cores.
  • Appendix B, Section B.3.1.1.2.3
  • Appendix B, Section B.3.1.1.2.4
  • Appendix B Figure B-3

You are still responsible for implementing any other updates that might have occured without the margin lines.  They are just there “for your convenience.”

What is actually included in MIL-STD-981?  The standard is layed out in the usual format:  Scope, Applicable Documents, and Definitions.  General Requirements follow, both for general procurement requirements and for the various types of devices covered by the standard.  Section 5, Detailed Requirements, is a lengthier review of the types of materials, inspections, markings, quality requirements, and so on that are expected for items delivered to meet this standard.  A short Section 6 with notes concludes the standard itself.

Two Appendices provide additional material.  Appendix A discusses the product assurance program required by this document.  Appendix B gives you information on real time X-ray (radiographic) inspection needed for compliance.
