This part of SAE J551 specifies on-board transmitter simulation test methods and procedures for testing passenger cars and commercial vehicles. The electromagnetic disturbances considered in this part of SAE J551 are limited to continuous narrow band electromagnetic fields. SAE J551/1 specifies general, definitions, practical use, and basic principles of the test procedure.

This part of SAE J551 specifies off-vehicle radiation source test methods and procedures for testing passenger cars and commercial vehicles. Two methods for calibrating electromagnetic fields are defined in the document: a substitution method and a closed-loop method. The substitution method is the method most commonly used. SAE J551-1 specifies general, definitions, practical use, and basic principles of the test procedure.

This SAE Standard covers the measurement of voltage transient immunity and within the applicable frequency ranges, audio (AF) and radio frequency (RF) immunity, and conducted and radiated emissions. By reference, ISO 11452-3, ISO 11452-7, ISO 11452-8, ISO 11452-10, ISO 11452-11, ISO 11452-2 and the emissions portion of ISO 7637-2 are adopted in place of SAE J1113-24, SAE J1113-3 , SAE J1113-22, SAE J1113-2, SAE J1113-28, SAE J1113-21 and SAE J1113-42, respectively. In the event that an amendment is made or a new edition is published, the new ISO document shall become part of this standard six months after the publication of the ISO document. SAE reserves the right to identify exceptions to the published ISO document with the exceptions to be documented in SAE J1113-24, SAE J1113-3, SAE J1113-22, SAE J1113-2, SAE J1113-28, SAE J1113-21 and SAE J1113-42 respectively. By reference, IEC CISPR 25 is adopted as the standard for the measurement of component emissions.
