Stripline Test Method to Characterize the Shielding Effectiveness of Conductive EMI Gaskets up to 40 GHz

2022-01-21
CURRENT
ARP6248
The purpose of this procedure is to establish a technique for reliably and repeatedly measuring the RF shielding characteristics of EMI conductive gasket materials and EMI conductive gaskets. Depending on the materials used for the construction of the measuring setup, the EMI conductive gaskets can be characterized against various joint surfaces. This standard will directly provide shielding effectiveness values up to 40 GHz, and will also be applicable for small samples of conductive EMI gaskets.

Guide to Civil Aircraft Electromagnetic Compatibility (EMC)

2022-06-24
CURRENT
ARP60493
This guide provides detailed information, guidance, and methods for demonstrating electromagnetic compatibility (EMC) on civil aircraft. This guide addresses aircraft EMC compliance for safety and functional performance of installed electrical and electronic systems. The EMC guidance considers conducted and radiated electromagnetic emissions and transients generated by the installed electrical and electronic systems which may affect other installed electrical and electronic systems on the aircraft. Application of appropriate electrical and electronic equipment EMC requirements are discussed. Methods for aircraft EMC tests and analysis are described. This guide does not address aircraft compatibility with the internal electromagnetic environments of portable electronic devices (PED) or with the external electromagnetic environments, such as high-intensity radiated fields (HIRF), lightning, and precipitation static.

Equivalence of Equipment Environmental Qualification Standards for Civil and Military Aircraft Equipment

2021-06-22
CURRENT
AIR6811
This document provides guidance for applying aircraft equipment electromagnetic, electrical, and mechanical qualification standards (i.e., DO-160, MIL-STD-461, MIL-STD-704, and MIL-STD-810) to civil aircraft certification intended for military use and for military aircraft equipment installed on civil aircraft. The guidance identifies where the equipment environmental qualification standards meet the intent of both the civil or military aircraft certification requirements. Conversely, the guidance will identify where the equipment environmental qualification standards have differences that do not meet the intent of the civil or military aircraft certification requirements and when these differences matter based on equipment criticality, installation location, and/or other variables.

Electromagnetic Interference Measurement Antennas; Standard Calibration Method

2003-02-12
HISTORICAL
ARP958D
This SAE Aerospace Recommended Practice (ARP) outlines a standard method for the checkout and calibration of electromagnetic interference measurement antennas. Its primary application is for use when measuring a source 1 m from the antenna in a shield room versus a source at a greater distance (far field). This is the typical distance used in performing military EMC testing. Thus, this is a method of calibration. Shield room characteristics are not considered. It does not address an unknown distributed source. Yet it is close to reality since it is based on another antenna that represents a distributed source. This document presents a technique to determine antenna factors for antennas used primarily in performing measurements in accordance with 2.1 and 2.2. The purpose of Revision B is to include the calibration of other antennas, such as small loop antennas that are also specified for use in these same references.

Electromagnetic Compatibility (EMC) System Design Checklist

2013-02-24
HISTORICAL
AIR1221
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 document establishes the minimum requirements for the electrical bonding and grounding of electric, avionic, armament, communication, and electronic equipment installations for aeronautical and aerospace applications. The bonding and grounding requirements specified herein are to ensure that an adequate low resistance return path for electric, avionic, armament, communication and electronic equipment is achieved which can withstand operating conditions and corrosion. This is essential for the reduction of coupling of electromagnetic fields into or out of the equipment as well as for providing electrical stability to control the currents and/or voltages caused by static charges and discharges and for suppressing the hazardous effects thereof.
