A draft of Revision G of MIL-STD-461 has not been released yet, but MET Labs has obtained information about proposed changes to the Military EMC test. As covered in this previous post, one of the primary changes is the incorporation of indirect lightning testing heavily leveraged off of Section 22 of RTCA/DO-160G. There is no lightning requirement in MIL-STD-461F, which was released in 2007.
There is one test that is very likely to be added to MIL-STD-461G: CS117
There are two additional tests that are being considered, but are much less likely to be included: RS106 & RS108
Information about the CS117 test:
- Derived from DO-160 Section 22 lightning induced transient susceptibility
- Includes Multiple Burst/Single Stroke same as DO-160
- Idea is not to change waveforms; services (Army, Navy, Air Force) would need to control the application
- Cable injection only – no pin injection testing
- Limited applicability (aircraft electronics) based upon specific program contact call out
Information about the RS106 test:
- Similar to RS105 (EMP free field test for equipment)
- Limited applicability – mainly for external stores (missiles, pods, ground equipment, etc.)
Information about the RS108 test:
- Similar to RTCA/DO-160 Section 23 Lightning Direct Effects
- Limited applicability (antennas or other external located items) based upon specific program contact call out
The rollout of MIL-STD-461G is currently scheduled for an initial draft in June 2013, a final draft in September 2013, and release in Fall 2014.
