MIL-STD-202 is a United States Military Standard that outlines test methods and procedures for the environmental and mechanical testing of electronic and electrical components and equipment. This standard aims to establish uniform test methods to evaluate the performance and reliability of these components and equipment under various conditions, including temperature, humidity, vibration, shock, and more.

MIL-STD-202 covers a wide range of tests, each designated by a specific method number, and it’s often used by the military, aerospace, and other industries where high reliability and durability of components are crucial. The standard helps ensure that electronic components and equipment can withstand the challenges of their intended operating environments.

The tests described in MIL-STD-202 are categorized into several sections, each addressing different environmental and mechanical stress testing aspects. Some of these categories include:

  1. Test Methods for Electronic and Electrical Component Parts: These tests focus on the reliability of electronic components like resistors, capacitors, connectors, and semiconductors.
  2. Test Methods for Electrical Connectors: This section covers tests for connector durability, electrical integrity, and other related properties.
  3. Test Methods for Printed Wiring Boards: These tests assess the reliability and durability of printed circuit boards used in electronic assemblies.
  4. Test Methods for Microwave Devices: This section focuses explicitly on microwave components and devices, including tests for their mechanical and electrical properties.
  5. Test Methods for Electronic and Electrical Equipment: These tests pertain to complete electronic and electrical equipment and systems, covering various environmental and mechanical stresses.

It’s important to note that while MIL-STD-202 is a well-known standard, its relevance has evolved over time due to technological advancements and changes in industry practices. Some organizations might still use this standard as a reference. Still, it’s possible that more up-to-date standards or industry-specific standards have been developed to address the evolving needs of modern electronic components and equipment.

Remember that standards might change over time, so it’s advisable to refer to the latest official documentation or standards organizations for the most accurate and current information.
