This Aerospace Information Report (AIR) is intended to provide information relating to the construction, calibration, and usage of parallel plate transmission lines in electromagnetic compatibility susceptibility testing.
The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI gasket materials and EMI gaskets against various joint surfaces. The procedure is also used to test the reliability of the gasketed joint combinations after being subjected to hostile environments.

This document presents standard methods to evaluate the common mode and differential mode insertion loss of passive electromagnetic interference power line filters from 10 kHz through 10 GHz. Insertion loss test methods for both quality assurance and performance prediction purposes are described. The performance prediction tests are selected to more closely approximate operating impedances. They are not intended to be inclusive or to represent worst case conditions. However, the methodology of this document can be used to determine the performance in an arbitrary impedance circuit.
This ARP provides the rationale and theory of charges being present on aircraft while on the ground. The necessary implementation of safety practices are explained and defined.
This checklist is to be used by project personnel to assure that factors required for adequate system electromagnetic compatibility are considered and incorporated into a program. It provides a ready reference of EMC management and documentation requirements for a particular program from preproposal thru acquisition. When considered with individual equipments comprising the system and the electromagnetic operational environment in which the system will operate, the checklist will aid in the preparation of an EMC analysis. The analysis will facilitate the development of system-dependent EMC criteria and detailed system, subsystem, and equipment design requirements ensuring electromagnetic compatibility.
This specification covers the general requirements for conventional AC and/or DC current carrying filter networks for the reduction of electromagnetic interference. A conventional filter is defined herein as a component containing definitive, lumped, R-L-C components and not employing distributed parameters as a required characteristic.
This Aerospace Recommended Practice (ARP) describes a standard method and means for measuring or calibrating the "Spectrum Amplitude" output of an impulse generator.

This AIR was prepared to inform the aerospace industry about the electromagnetic interference measurement capability of spectrum analyzers. The spectrum analyzers considered are of the wide dispersion type which are electronically tuned over an octave or wider frequency range. The reason for limiting the AIR to this type of spectrum analyzer is that several manufacturers produce them as general-purpose instruments, and their use for EMI measurement will give significant time and cost savings. The objective of the AIR is to give a description of the spectrum analyzers, consider the analyzer parameters, and describe how the analyzers are usable for collection of EMI data. The operator of a spectrum analyzer should be thoroughly familiar with the analyzer and the technical concepts reviewed in this AIR before performing EMI measurements.
This document contains a "sample" Control Plan with explanations as to the intended content of various sections. It also can serve as a sample technical construction file as specified by the European EMC Directive.
