Vibration specification - soldier carried electronic gear

[mechengdude]

Does anyone have a reference for a vibration/shock specification used for soldier/personnel carried electronic gear such as a backpack mounted radio?

MIL-STD-810 doesn't seem to address the topic. Thanks in advance.

Well, one could possibly envision using 810 bench-handling environment as the shock input. Given that most soldiers seem to spend quite a bit of time in HMMWVs, you should use a HMMWV vehicle vibration environment as a minimum, but should probably use a truck transport environment as the design level.

The 810 does not apply for personell carried equipment. The body will act as a spring/damper system completely different form any vehicle.

The point was that soldiers tend to drop, bang, and throw things, so bench handling is one plausible simulation.

However, most equipment that are hand movable should probably get straight drop tests, like from 3 or 4 ft.

MBITR tactical radios quote ANSI/TIA/EIA-603-1992 for shock and vibe standards. Personally I've never read that standard, but that might be a good starting point for you.

MBITR datasheet is available at

MIL-STD-810 I think gives values for minimum Integrity, which covers transient drops and handling shock and vibrations.

The 810 MIT is a broad spectrum vibration test, essentially comparable to an ESS. It's not intended to simulate operational conditions.
