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 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 level 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 covers the measurement of Impulse Electric Field Strength radiated over the frequency range of 30-1000 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.

This standard covers the measurement of radiation from all motor vehicle sources (including auxiliary engines) with the exception of short duty cycle equipment, such as starting motors, window regulators, turn signals, etc., over a frequency range of 20-1000 MHz.

This standard covers the measurement of electromagnetic radiation from a motor vehicle or other internal-combustion-powered device (excluding aircraft) over a frequency range of 20-1000 MHz. In the case of motor vehicle sources, auxiliary engines mounted on the vehicle are included and short-duty cycle equipment (such as starting motors, window regulators, turn signals, flashing warning lights, etc.) are excluded.
