Scope
Ballot to Brake Effectiveness and Dynamometer Effectiveness - 11/19/98 Results of ballot: Brake Effectiveness - A-6, D-2, W-1, NR-2 Dynamometer Test Code - A-5, D-0, W-0, NR-2 Jim Trainor will send letter to the two people who disapproved and send a copy of the letter to SAE - 7/7/1999 Transmittal sent to pubs - 8/30/1999 Pre-print sent to sponsor - 10/27/1999 Signed copy sent to pubs - 11/9/1999 Published copy (AUG99) received - 01/14/2000
Rationale
This Recommended Practices has been replaced by the SAE J2784 based on (1) SAE J2784’s ability to better reproduce the FMVSS sequences for vehicles with Gross Vehicle Weight Rating of 4,540 kg or less, (2) industry consensus to simplify the number of dynamometer testing for performance evaluation, and (3) availability of more specific procedures to assess friction behavior (sensitivity) as a function of speed, pressure, temperature, and braking history like SAE J2522 and ISO 26867, which are used on a regular basis by the automotive industry.

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.
