Hello K,
I know its not in in Greek, but the document is very detailed. Its nearly 100 pages, including the vibration specification down to Hz, the drop heights, water proofing, electrical stress levels, etc., including the number of repetitions and how to conduct the test.
If any consumer device can pass those specs, its pretty impressive. But it shows were the other costs for the 87V is compared to the 17B, its beyond electrical, if these meters are made to some or all of these specifications.
Here's the summary page.
I took the time to read it all of it .. actually two times.

Its not that simple to understand the terms in it , mostly because it refers to special units, like the force measured in G .. so the explanations and the descriptions are very specialized.
And I discovered and something more , Fluke in the public specs indicates max transients of 8KV ,
the Mil specs document says clearly , that any device that claims transients of 10KV , it will be tested if it comply to specs, so by this cheap trick , the 87 series never got tested that high.
The Mil specs class 2 , its a bit forgiving in all aspects in comparison with the class A.
Still I would feel happier if it was class 5 and cost the 1/4 of the price.
