Developed by the US Department of Defense, the MIL–STD-810G is a test series designed to judge the durability and lifespan of equipment under various forms of physical stress. MIL-STD-810G 516.6 refers to the Transit Drop Test, Method 516.6 Procedure IV, which outlines the drop test parameters. In order to receive certification, each case must be dropped onto concrete 26 times from a height of 48 inches onto every corner and edge. Method 516.7, which the ArmadilloTek cases underwent, is the same test except that the cases are dropped onto steel reinforced with concrete.
Actually we are way better and exceeded 2X MIL–STD-810G.
