And if you thought the old MIL-STD-810G was massive in size, the new one is bigger yet. While the old MIL-STD-810G document was 804 pages, the new one has 1,089. That’s 285 extra pages of testing procedures. The new standard brings quite a few changes in ruggedness testing. In this article I’ll take a first look at one of the marquee tests as far as rugged mobile computing equipment goes, the transit drop test. It was described in Method 516.6 Procedure IV in the old MIL-STD-810G, and now it is under Method 516.8 Procedure IV in the new MIL-STD-810H.
