Aerospace Systems Electrical Bonding and Grounding for Electromagnetic Compatibility and Safety
2012-08-10
CURRENT
ARP1870A
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.

Alternative (Ecological) Method for Measuring Electronic Product Immunity to External Electromagnetic Fields
2008-08-25
HISTORICAL
ARP5889
This method is used to define the immunity of electric and electronic apparatus and equipment (products) to radiated electromagnetic (EM) energy. This method is based on injecting the calibrated radio frequency currents (voltages) into external conductors and/or internal circuits of the product under test, measuring the strength of the EM field generated by this product and evaluating its immunity to the external EM field on the basis of the data obtained. The method can be utilized only when it is physically possible to connect the injector to the conductors and/or circuits mentioned before.

CAPACITOR, 10 MFD FOR EMI MEASUREMENTS

ARP936
This recommended practice describes the requirements of a special purpose 10 mfd feed through capacitor to be used in series with the power line to an electrical or electronic device during EMI tests.

Cabling Guidelines for Electromagnetic Compatibility
2009-11-22
CURRENT
AIR1394A
These cable practice recommendations tend toward design guidance rather than standardization. EMC achievement tests can be standardized, but the means for achievement should not be constrained. The material can best be described as an essay on cabling, and the theme is that a cable is just a part of a complete circuit, the interconnect circuit. Cable EMC performance is thus determined largely by circuit design; it is unrealistic to expect cabling techniques to compensate for improper impedance, symmetry or waveform in the circuit.

Corrosion Control and Electrical Conductivity in Enclosure Design
2024-02-27
CURRENT
ARP1481B
Corrosion control is always of concern to the designer of electronic enclosures. The use of EMI gaskets to provide shielding often creates requirements that are in conflict with ideal corrosion control. This SAE Aerospace Recommended Practice (ARP) presents a compatibility table (see Figure 1) which has as its objective a listing of metallic couples that are compatible from a corrosion aspect and which still maintain a low contact impedance.

ELECTROMAGNETIC COMPATIBILITY ON GAS TURBINE ENGINES FOR AIRCRAFT PROPULSION
2008-08-25
HISTORICAL
AIR1423
The purpose of this AIR is to acquaint the aerospace industry with problems in attaining electromagnetic compatibility on gas turbine engines, particularly as used in aircraft. It is also the purpose of this AIR to present guidelines for the application of EMC controls to the engine, to its components which of necessity must operate in very hostile environments and to its interface with the aircraft.

ELECTROMAGNETIC INTERFERENCE MEASUREMENT ANTENNAS; STANDARD CALIBRATION METHOD
1996-03-01
HISTORICAL
ARP958B
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.
