MIL-STD-202G Defense Division Test Method Standard: Electronic and Electrical Components

Uniform methods for testing electronic and electrical component parts in MIL-STD-202G, a United States military defense standard, including basic environmental testing and physical and electrical testing to determine resistance to the harmful effects of the natural elements and conditions surrounding military operations is explained. For the purpose of this standard, the term component parts includes capacitors, resistors, switches, relays, transformers, inductors and similar items. This standard is intended to be applied only to small component parts weighing up to 136 kg or with a root mean square test voltage of up to 50 volts, unless otherwise specified.

The following objectives were aimed at in developing these test methods :

• To specify the appropriate conditions that can be obtained in the laboratory that gives test results similar to the actual service conditions available in the field and to obtain the repeatability of the test results. The tests described herein should not be construed as an accurate representation of actual service operation in any geographic location.
• To collect the following methods in a standard:
  • All test methods of similar character seen in various common or single service electronic and electrical component parts specifications
  • Test methods suitable for use in a variety of specifications
  • Test methods in which component parts will be tested under certain currently standardized test procedures, in particular temperatures, barometric pressures and similar recognized extreme environments.
• Apply the test methods described for environmental, physical and electrical testing to parts not covered by an approved military specification, military form standard, specification sheet or drawing, where appropriate.

Briefly, the purpose of this standard is to describe uniform procedures for environmental, physical and electrical testing of electronic and electrical component parts. It is intended to be a reference document for testing requirements described in military component standards and, where specified, other procurement standards and drawings.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides military-purpose electronic and electrical parts testing services within the scope of MIL-STD-202G standard, with its trained and expert staff and advanced technological equipment.
