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).

The limits in this SAE Standard are designed to provide protection for receivers of all types of radio transmissions when used in buildings. As a result, receivers of radio transmissions used out-of-doors may not be protected by the limits specified. This publication applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from: a Vehicles propelled by an internal combustion engine, electrical means or both (see SAE J551/1 for definition) b Motorboats propelled by an internal combustion engine, electrical means or both NOTE—For the purposes of this publication, motorboats are considered to be a subset of vehicles unless specifically mentioned to the contrary. c Devices equipped with spark-ignited internal combustion engines (see SAE J551/1 for definition) This publication does not apply to aircraft, traction systems (railway, tramway, and trolley bus), or to incomplete vehicles.

This SAE Recommended Practice covers the recommended testing techniques for the determination of electric field immunity of an automotive electronic device when the device and its wiring harness is exposed to a power line electric field. This technique uses a parallel plate field generator and a high voltage, low current voltage source to produce the field.

This part of SAE J1113 specifies the direct RF power injection test method and procedure for testing electromagnetic immunity of electronic components for passenger cars and commercial vehicles. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous, narrowband conducted RF energy. This test method is applicable to all DUT leads except ground. The test provides differential mode excitation to the DUT. Immunity measurements of complete vehicles are generally only possible by 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 for components shall be applied by the manufacturer. This method is suitable over the frequency range of 250 kHz to 500 MHz.

The process described in this document is generally applicable to provide a means to classify the function performance status of automotive electronic devices. Testing of devices could be performed either on or off vehicles. Appropriate test pulse and methods, functional status classification, region of performance, and test pulse severity level would have to be specified in the individual cases.
