MIL-STD-461G

This Standard contains materiel acquisition program planning and engineering direction for considering the influences that environmental stresses have on materiel throughout all phases of its service life. It is important to note that this document does not impose design or test specifications. Rather, it describes the environmental tailoring process that results in realistic materiel designs and test methods based on materiel system performance requirements.

MIL-STD-461 is a United States Military Standard developed to define how equipment should be tested in regards to their electromagnetic compatibility. The most recent version of MIL-STD-461 is the MIL-STD-461G, which is the result of several corrections over years. However, there are still many military contracts mandating the compliance to MIL-STD-461F.

MIL-STD-461 is basically is a military standard and thus not mandated outside the US military, but several civilian agencies and corporates also adopt this standard as it provides comprehensive procedures and guidelines in the field of electromagnetic. Plus, in order to sell their products and services to military, companies establish their anechoic chamber to conform to MIL-STD-461 in electromagnetic compatibility test labs. In other words, civilian organizations use MIL-STD-461 for two reasons:

This standard regulates interface and the relevant verification criteria in order to monitor the emission of an electromagnetic interference (EMI) and its liability associated with electronic, electrical, and electromechanical tools and subsystems created or assembled to be employed in any missions or activities related to the Department of Defense (DoD). The stated equipment and subsystems could be applied individually or as an essential component of other subsystems or systems. MIL-STD-461 is mostly suitable for the elements with the following qualities:

• Electronic enclosures that are no larger than an equipment rack
• Electrical interconnections that are distinct wiring harnesses between enclosures
• Electrical power input coming from prime power sources

MIL-STD-461 should not, however, be used in the elements such as modules positioned within electronic enclosures or the whole platforms. Though, the rationale of the standard could be helpful to use as a foundation for developing appropriate characteristics for those applications.
