Issuing Committee
Brake Dynamometer Standards Committee
The Brake Dynamometer Standards Committee is part of the Foundation Brake Steering Committee that reports to the Motor Vehicle Council. The committee is responsible for developing standards, recommended practices, and information reports for brake dynamometer testing, for on-road vehicles below 4540 kg of Gross Vehicle Weight Rating. The committee also maintains liaison activities with other Standard Development Organizations or industry consortia.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
