SPECIAL FEATURE
The physics of such shock propagation are not particularly well understood and simulation can be difficult and misleading. The best way to perform the test may be to mount the equipment in the actual vehicle and shoot it with appropriate non-exploding ammunition. This is an expensive test and generally not available at civilian test labs.
RFQ Specification Confusion Often an opportunity to bid will be posted by a military customer wherein the statement “Must meet MIL-STD-810G” is included. What exactly does that mean? There are 28 distinctly different Methods included in 810G. Perhaps a major program such as the F-35 Joint Strike Fighter will be tested to most of the 28 Methods but should it be subjected to Method 526 for Rail Impact—for transport on rail cars? Items such as rackmount computers or LCD displays should be tested to an appropriate sub-set of Methods but certain Methods, such as Method 509.5 (Salt Fog), are certainly not applicable and
