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This Recommended Practices has been replaced by the SAE J2784 based on (1) SAE J2784’s ability to better reproduce the FMVSS sequences for vehicles with Gross Vehicle Weight Rating of 4,540 kg or less, (2)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.
