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.
The rationale is that through years of effort to harmonize the SAE and ISO documents, J551-12 and J551-13 are technically identical with their ISO counterparts. To keep SAE out of copyright difficulties, we are adopting the ISO documents by referece in J551-1 and cancelling J551-12 and J551-13 SAE documents. We have reserved the document numbers so that should technical differences arise, we can document the differences in logical fashion.
