MIL-STD-461 Test

MIL-STD-461 provides the requirements for the control of electromagnetic interference (EMI) emissions and susceptibility characteristics of electronic, electrical and electromechanical equipment and subsystems designed or supplied for use by Ministry of Defense activities and agencies.

MIL-STD-461 Test

This standard is best suited for benchtop or pedestal equipment with a power input current draw of less than 200 amps. It is not commonly applied to items such as components and independent modules contained in electronic enclosures, or to all platforms such as aircraft or submarines.

However, the principles used here can be useful as a basis for developing appropriate requirements for any application. NTS carried out tests in the home laboratory on equipment up to 10 meters in length exceeding 22 feet. In addition, EUROLAB routinely performs on-site testing (on-site) for equipment that is too large or complex to carry.

MIL-STD-461 has been an active document since 1967 and has undergone many major revisions over the years. These changes are largely based on observed changes in electronic use and advances in technology in a platform's Electromagnetic Environment (EME). Interestingly, legacy programs and strengthening activities can still refer to previous versions of this document to ensure that there has been no impact since the original compliance report.

MIL-STD-461 Revision Requirements

EUROLAB is considered as an expert in MIL-STD-461 testing and can test all revisions of this standard (MIL-STD-461 A - G) with full control. The most common requirements from E&F revisions are shown below, MIL-STD-461G version released in December 2015.

MIL-STD-461 Engineering Services

EUROLAB offers EMI / EMC engineering services in a number of on-site:

  • Training courses - from a basic overview of MIL-STD-461 qualification requirements, to the latest product design methodologies used to meet these requirements.
  • Product design review and EMI troubleshooting
  • EMI Test Procedure development

The EMI Test procedure (EMITP) is one of the most important elements of a MIL-STD-461 qualification program. Test procedure control requirements are defined under DI-EMCS-80201C. It aimed to organize the test methodologies used, define test limits and levels, and explain how the tested equipment (EUT) will be operated, guided, and electrically grounded during each test.

It also provides a tool to describe any tailoring activity or deviations from MIL-STD-461 standard requirements (when required) to obtain agency approval prior to testing. EUROLAB works with product manufacturers to develop official MIL-STD-461 test procedures and will assist you in the approval process.
