Part of MIL-STD 810G for Notebooks:
Water immersion (Method 512.5) – Testing for water resistance is done in a rain chamber that drenches products with jets of water over varying intensities and angles. Fully rugged models are tested for full water immersion.
Salt and fog (Method 509.5) – Salt and fog can cause electronic equipment to short circuit or rust. Equipment is tested using a 5% saline solution.
Humidity (Method 507.5) – Extreme humidity causes computers to corrode and malfunction. Equipment is tested with 95% humidity.
Sand and dust (Method 510.5) – Equipment is tested to resist the effects of dust particles which may penetrate into cracks, seals, and keyboards. The equipment is also tested to determine whether the computer can be stored and operated in blowing sand conditions without experiencing degradation of its performance, effectiveness, reliability and maintainability due to the abrasion/erosion or clogging effect of large, sharp-edged particles.
Temperature (Method 501.5, 502.5, 503.5) – Equipment is tested at temperatures down to 33 degrees Celsius and up to 71 degrees Celsius, as well as for temperature shock resulting from extreme swings in temperatures.
Sun exposure (Method 505.5) – Equipment is tested for direct sunlight for 3 to 7 days in a solar chamber.
Shock and drop testing (Method 516.6) – Equipment is tested to operate under 75 times the force of gravity and dropped from 3 to 4 feet while operating, multiple times.
Vibration (Method 514.6) – Equipment is tested in standard vehicles and in vibration-prone vehicles such as tanks.
Low pressure (Method 500.5) – Equipment is tested for low pressure atmosphere, such as experienced at high altitudes or dropping pressure in an aircraft.
