MIL-STD-202

MIL-STD-202

A legal requirement that regulates the testing procedure for all system parts and products with printed circuit boards is MIL-STD-202. The MIL-STD-202 test, one of the most important legal requirements for defense contractors today, lays out precise instructions to make sure your product is prepared for the market.

Services for MIL-STD-202 Testing:

Testing by MIL-STD-202 is a big part of what we perform at Infinita Labs. We take great pleasure in being able to comply with all MIL-STD-202 test procedures, including:

• Electrical tests that measure capacitance, insulation, voltage, and DC or ohmic resistance.

• Tests of physical attributes such as high-impact shock, solvent resistance, acceleration, and vibration.

• Environmental tests, such as those for flammability, explosion, sand and dust, thermal stress, humidity, and salinity.

MIL-STD-202 Testing Procedures

Basic environmental tests and other techniques for testing electrical component parts and electronic parts are established by MIL-STD-202. Our MIL-STD-202 testing services assess a person’s resilience to the weather and situations that can affect military operations, physical tests, and electrical tests.

• Regarding the MIL-STD-202 standard, component parts include relays, switches, capacitors, relays, inductors, and transformers. The following techniques are used to test military electrical components:
• Low-level switching test method 311: Analyzes electrical contact dependability under low-level switching conditions
• Determines electrical contact dependability under situations of intermediate current switching using test method 313
• Test Technique 304 Measures the % change in ohmic resistance for the resistance temperature characteristic.
• Direct current resistance of conductors, electromagnetic component windings, and resistors are all measured using Test Method 303 DC resistance.
• Test Procedure 302 Measures a component’s capacity to withstand an impressed direct voltage through its insulation resistance.
• Determines whether a component part can function safely at its rated voltage using test method 301, “Dielectric withstanding voltage”
• Determines whether markings will prevent discoloration and stay readable when exposed to solvents using Test Method 215: Resistance to Solvents.
• Test Method 214 Random vibration: Evaluates the dynamic stress resistance of component elements to random vibration.
• Test Method 213 Shock (Specified Pulse): Examines the response of the component parts to shocks.
• Determines how component parts are impacted by acceleration stress using Test Method 212 Acceleration.
• Examines the effects of rotation on electrical and electronic components using Test Method 206 Life (rotational).
• Test Procedure 204 High-frequency vibration: Investigates the effects of vibration on various frequency ranges on component elements.
• Test Method 203 Random drop: Measures the repeated, random impact brought on by shipping, handling, and other field service circumstances.
• Determines the effects of vibration on component parts using Test Method 201 Vibration.
• Test Procedure 110 Evaluation of the equipment’s resistance to exposure to fine sand and dust
• Determines how parts respond to high ambient temperatures using Test Method 108 Life (at raised ambient temperature).
• Thermal shock test method 107 evaluates a component’s resistance to exposure to extremely high and low temperatures as well as the shock of alternating exposures.
• Moisture resistance test method 106 measures a material’s resistance to the damaging effects of excessive heat and humidity.
• Test Procedure 105 Barometric Pressure (Reduced): Evaluates the capacity of components to prevent voltage failures
• Determines whether component part seals are effectively using test method 104 immersion.
• Test Procedure 103 examines how the characteristics of materials are affected by moisture in a steady state.
• Test Method 101 Salt Atmosphere (Corrosion): Evaluates the resistance to corrosion of components.
