With the advent of computer based electronics being utilized in automobiles, the Electromagnetic Radiation Subcommittee has deemed it prudent that a new test method be written to provide a common test for the measurement of narrowband radiation from vehicles and devices. This SAE Standard covers methods of measuring incidental narrowband radiation from vehicles and devices. The standard also establishes performance levels intended to protect nearby communication and broadcast receivers. It is intended to serve as an alternate method of measuring electromagnetic radiation which is analogous to the FCC Part 15 methodology but adapted to measuring vehicles. The equivalent procedures for broadband emissions are set forth in SAE J551. This standard covers narrowband emissions in the frequency range of 10 kHz to 1000 MHz. An example of such radiation is the unintended emission from on-board logic and computer modules.

This SAE Recommended Practice establishes uniform laboratory techniques for the measurement and determination of the susceptibility of electromagnetic interference of electrical, electronic and electromechanical ground vehicle components.

This SAE Recommended Practice establishes uniform laboratory measurement techniques for the determination of the susceptibility to undesired electromagnetic sources of electrical, electronic, and electromechanical ground-vehicle components. It is intended as a guide toward standard practice, but may be subject to frequent change to keep pace with experience and technical advances, and this should be kept in mind when considering its use.

This information report gives typical requirements for an anechoic chamber in which the system susceptibility of an operating motor vehicle to electromagnetic fields can be determined in the frequency range of 20 MHz to 18 GHz. Because of the large cone sizes required for 20 MHz cut-off, several anechoic facilities have been designed with lower cut-off frequencies of 200 MHz or greater. Testing below cut-off is then accomplished using customized antennas at reduced accuracy. Users should carefully review their testing requirements before undertaking the construction of a test facility the magnitude of an anechoic chamber. Other test approaches include, but are not limited to, open field testing per SAE J1338 and mode stirred reverberation chambers.

This SAE Standard covers the measurement of Impulse Electric Field Strength radiated over the frequency range of 20–1000 MHz from a vehicle or other device powered by an internal combustion engine or electric motor. Operation of all engines (main and auxiliary) on a vehicle or other device is included. All equipment normally operating when the engine is running is also included, except operator-controlled equipment, which is excluded. The recommended limit applies only to complete vehicles or devices in their final manufactured form. Vehicle mounted rectifiers used for battery charging in electric vehicles are included in this specification when operated in their charging mode.

This SAE Standard contains limits1 and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 1000 MHz. The standard applies to any electronic/electrical component intended for use in vehicles and large devices. Refer to International Telecommunications Union (ITU) Publications for details of frequency allocations. The limits are intended to provide protection for receivers installed in a vehicle from disturbances produced by components/modules in the same vehicle.2 The receiver types to be protected are: sound and television receivers3, land mobile radio, radio telephone, amateur and citizens' radio. For the purpose of this document, a vehicle is a machine which is self-propelled. Vehicles include (but are not limited to) passenger cars, trucks, agricultural tractors, and snowmobiles. The limits in this document are recommended and subject to modification as agreed between the vehicle manufacturer and the component supplier.

This SAE Standard defines methods and apparatus to evaluate electronic devices for immunity to potential interference from conducted transients along battery feed or switched ignition inputs. Test apparatus specifications outlined in this procedure were developed for components installed in vehicles with 12-V systems (passenger cars and light trucks, 12-V heavy-duty trucks, and vehicles with 24-V systems). Presently, it is not intended for use on other input/output (I/O) lines of the device under test (DUT).

This part of SAE J1113 specifies test methods and procedures for testing electromagnetic immunity (of vehicle radiation sources) of electronic components for passenger cars and commercial vehicles. To perform this test method, the electronic module along with the wiring harness (prototype or standard test harness) and peripheral devices will be subjected to the electromagnetic disturbance generated inside an absorber-lined chamber. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous narrowband electromagnetic fields. Immunity measurements of complete vehicles are generally only performed at the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes, or the large number of different vehicle models. Therefore, for research, development and quality control, a laboratory measuring method shall be applied by the manufacturers.
