scope:

General applicability

This standard establishes interface and associated verification requirements for the control of the electromagnetic interference (emission and susceptibility) characteristics of replaceable electronic modules. Such equipment is used only as an integral part of other subsystems or systems, and may not be used independently. This standard is best suited for items that have the following features: removable/replaceable electronic circuit card modules that plug into an equipment rack or frame, with electrical interconnections primarily through edge connectors that interface directly with a backplane, and electrical power input derived from the backplane power sources. This standard should not be directly applied to equipment that can be used independently as a stand-alone system or subsystem (separate box intra-connected by a wire harness to other boxes of a subsystem), or to entire system platforms. It is assumed that the rack/frame equipment with its full complement of REMs is tested in some configuration to an equipment EMI standard such as MIL-STD-461E. This standard is best suited for situations where the qualification of the REM is more effective than requalification of the rack/frame equipment with the new REM.

Tailoring of requirements

Application-specific environmental criteria may be derived from operational and engineering analyses on the REM being procured for use in specific systems or platforms. When analyses reveal that the requirements in this standard are not appropriate for that procurement, the requirements may be tailored and incorporated into the request for proposal, specification, contract, order, and so forth before the design is completed. The test procedures contained in this document shall be adapted by the testing activity for each application. The adapted test procedures shall be documented in the electromagnetic interference verification (EMIV), (See A.6.2). The annex of this standard provides guidance for tailoring.

Purpose

The purpose of the standard is to provide interface and associated verification requirements for the control of the electromagnetic interference (emission and susceptibility) characteristics of REMs
