The SAE RFI Specification--A Living Document

During the past 40 years, the automobile industry has taken the lead in initiating and pursuing programs to measure and control electromagnetic interference from vehicles and has sought to assure compatibility of vehicles with other equipment. It has a long and successful history of cooperation in the development and use of standards relating to control of radio frequency emissions. Although the earliest efforts by the industry were aimed at protecting onboard entertainment radios, protection of other communications services has since been given primary consideration as the need for such protection was identified. This presentation will trace the history of the development of the SAE standard for measurement of electromagnetic radiation from motor vehicles from its inception, treating the need for each revision and method of acquiring the data necessary for accomplishing revision. The greatest emphasis will be placed on the latest and most extensive revision of the standard, copies of which will be available at the meeting. The report also will update the status of the SAE measurement procedure in the world community and its relationship to measurement procedures specified by other standards writing groups. Also treated in this presentation will be goals for the future of the standard, one of which is to make it a more internationally acceptable standard.
