In a discussion of MIL-STD 810:

I guess the real point here about various standards and with
regards to anecdotal stories about "Well this did..."

The bottom line on buying hardware for adverse conditions is
whether or not the manufacture is willing to say that it
"Absolutely and without fail will work under the following
conditions."

As opposed to specifying a narrow range and if works out side
of that, well, fine.

Also, remember, advertising is based on the perception by
marketing as to who the potential buyer is.

If there was a "MIL-STD-xxx" specifying that a piece of
equipment should be shiny and have lots of buttons, they'd
be pushing that too.
