Regulations define scope criteria that qualify a device under test (DUT) for deployment into its application environment, such as commercial electronics and industrial controllers. The concept can also be applied for military purposes, as civilian IEC60945 requirements for marine telecommunication are no less restrictive than military MIL-STD-461. However, military regulations set strict standards for equipment to survive the harsh environment of the battlefield and maintain functionality after various impacts, high temperatures, and EMS interference.
Common Standard for Electronical Equipment
The well-known MIL-STD is the US military standard for electronic equipment, it includes MIL-STD-810, MIL-STD-461 and MIL-STD-202.
MIL-STD-810
Includes vibration, shock, extremes in temperature, humidity, salt spray for simulating harsh environments.
Shock, Vibration
Extreme Temperature
Salt Fog
MIL-STD-461
Provides electromagnetic compatibility constraints for equipment operating in military vehicles.
Conduction EMI/EMS
Radiation EMI/EMS
MIL-STD-202
Defines general test methods for the environmental, physical and electrical performance of electrical components.
Environment
Physical Performance
Electronic Performance
Military regulation defines its detailed requirements that bring benefits to system integration. A system without properly defined requirements may easily face the conflict among its components.
Essential to military operation
Communication and reconnaissance are essential to military operation and hence there are many RF devices and kinds of sensors in a military vehicle. Such as sonar were deployed within ship and submarine. The constrains in MIL-STD-461 for ship has extend EMC range to audio frequency used in sonar, reducing the difficulty of system integration.
Survive through the most of harsh environment
Military regulations well defined the requirements of application. Just follow the reulations, all equipment can survive through the most of harsh environment in battlefield and can easily integrated into a vehicle with other equipment.
