Military Testing

MIL-STD-202 Testing

Electronic & Electrical Component Testing Standards

MIL-STD-202 establishes uniform methods for testing electronic and electrical component parts, including basic environmental tests to determine resistance to deleterious effects of natural elements and conditions surrounding military operations, and physical and electrical tests. For the purpose of this standard, the term “component parts”: includes such items as capacitors, resistors, switches, relays, transformers, inductors, and others. This standard is intended to apply only to small component parts, weighing up to 300 pounds or having a root mean square test voltage up to 50,000 volts unless otherwise specifically invoked.

Test Method Test
101 Salt Atmosphere (Corrosion)
103 Humidity (Steady State)
104 Immersion
105 Barometric pressure (reduced)
106 Moisture Resistance
107 Thermal Shock
108 Life (at elevated ambient temperature)
110 Sand and Dust Testing
201 Vibration Testing
203 Random Drop
204 Vibration Testing High Frequency
206 Life (rotational)
212 Acceleration
213 Shock (specified pulse)
214 Random Vibration Testing
215 Resistance to Solvents
301 Dielectric withstanding voltage
302 Insulation resistance
303 DC resistance
304 Resistance temperature characteristic
311 Life, low-level switching
312 Intermediate current switching

The user of the standard must also decide interdependently of the standard, how much additional test margin to allow for the uncertainty of test conditions and measurement in each test.
