MIL-STD (Military Standard) or MIL-SPEC (Military Specification)

The MIL-STD specification is a series of guidelines established by the U.S. Department of Defense in order to define specific performance and manufacturing requirements for all types of equipment.

In most cases, products must be designed in accordance with the MIL-STD to be considered acceptable for use by the U.S. Department of Defense. A product's MIL-STD compliance is also a consideration for many state and local governments when purchasing mobile computers for use in public safety, emergency services, maintenance, etc.

The MIL-STD 810F standard was released on January 1, 2000 (superseded MIL-STD 810E). MIL STD 810F includes testing protocols to simulate environmental stresses from rain, humidity, salt fog, sand/dust, vibration, shock, temperature, etc. A copy of MIL-STD 810F can be downloaded from the United States Army Developmental Test Command.

The MIL-STD 810F standard is an all-encompassing standard that is frequently used for ruggedization testing by mobile computer manufacturers. Many manufacturers and laboratories will design their ruggedization testing in accordance to the MIL-STD 810F guidelines. However, it is important to note that when the MIL-STD 810(x) specification is listed on a product's data sheet, this usually only applies to the vibration and shock component of the standard, and does not mean that protection is included from salt fog, corrosion, rain, humidity, temperature, etc. Therefore, IP or NEMA Ratings are frequently used to signify protection from liquids and solids, and the MIL-STD is used to specify protection from shock and vibration.
