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.

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 impulsive electromagnetic radiation over the frequency range of 20 to 1(100 MHz from a motor vehicle or other device powered by an internal combustion engine. 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.

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.

Vehicle electrical/electronic systems may be affected when immersed in an electromagnetic field generated by sources such as radio and TV broadcast stations, radar and communication sites, mobile transmitters, cellular phones, etc. This part of SAE J551 specifies off-vehicle radiated source test methods and procedures for testing passenger cars and commercial vehicles within a Reverberation Chamber. The method is used to evaluate the immunity of vehicle mounted electronic devices in the frequency range of 80 MHz to 2 GHz, with possible extensions 20 MHz to 10 GHz, depending upon chamber size and construction. Three methods for calibrating and applying electromagnetic fields are described in the document: 1) Mode Tuned Reverberation Chamber method, 2) Mode Stir (Standard) Reverberation Chamber method and 3) Mode Stir (Hybrid) Reverberation Chamber method.
