SMC-T-008: “Tailoring for AIAA S-121A-2017, Electromagnetic Compatibility Requirements for Space Equipment and Systems”
The Air Force Space Command has created its own set of EMC/EME requirements through the Space and Missile Systems Center. These documents are meant to apply largely to satellites and launch vehicles. In 2008 SMC-S-008 was developed as a way to provide verification methods for most of the requirements of both MIL-STD-461 AND MIL-STD-464. In 2019, SMC-T-008 was released, superseding the 2008 version. According to the front matter, one of the goals of the new edition was to reduce the number of “shall” statements that needed to be tracked. See figure below, where “Tailored AIAA-S-121” means SMC-T-008.
So SMC-T-008 eliminated as many “low risk” requirements as it could. It also reduced as much text as possible, and simply refers to each section of AIAA-S-121, which also encompasses both MIL-STD-461 and -464, with either a statement of “There are no changes to this section” (no shall statement!) or a statement on how to re-word AIAA-S-121 for their purposes, as in: “Insert “, subsystem, and unit” between “system” and “level” in the first sentence of AIAA S-121A-2017, Section 6.1.2.” (still no shall statement!). This certainly makes it a shorter document, but it cannot be used without having a copy of AIAA-S-121 to read in parallel, and the AIAA standard must be purchased. You can freely download SMC-T-008 here, or SMC-S-008 here, or purchase AIAA-S-121 here. [To be fair, I believe the “shall” count of Figure 1-1 includes applicable “shalls” found in AIAA-S-121, even if they’re not directly quoted in SMC-T-008 but are still applicable. But still!]
TIP:
SMC-S-008 is an excellent, publicly available document that shows methods of compliance for all of MIL-STD-464–not just the EMC-specific portions that the better known MIL-STD-461 test methods address. For instance, it’s one of the few places you’ll find a referenced test method to verify the multiplication requirement. (Multipaction is a destructive phenomenon that can affect high power RF systems. The verification method you’ll find in SMC-S-008, or AIAA-S-121 behind a paywall, but not in MIL-STD-464 is “ECSS-E-20-01A, paragraphs 4.4, 4.5, 5.1-5.6, 6.2-6.6.4, 7.1-7.3.2, 8.1-8.4.2, Annex B, Annex D and Annex E”.) Consider looking it up when trying to parse MIL-STD-464 sections and verification requirements.
