The DoD has a series of 23 tests to determine how any piece of equipment, including laptops, will hold up in various environments. The least version of their standardized testing methods is called MIL-STD-810G, and it measures everything from water and shock resistance to how well a device handles the elements, including fungus build-up and low-pressure situations.
You\’ll often see the test results measured by the IP code, short for International Protection rating. It\’s a simple two number system, with one digit representing a product\’s resistance to solid objects, while the other measures how well it shrugs off water.
For example, for a laptop rated IP65, the \”6\” signifies the laptop is dust tight and offers complete protection against the tiny particles. This is the highest designation. The \”5\” signifies the device can withstand water jets. This scale goes up to \”8,\” which means the device is functional immersed in depths beyond one meter.
