FMVSS 135 Inertia Dynamometer Test Procedure

Scope
This Recommended Practice is derived from the Federal Motor Vehicle Safety Standard 135 vehicle test protocol as a single-ended inertia-dynamometer test procedure. It measures brake output, friction material effectiveness, and corner performance in a controlled and repeatable environment. The test procedure also includes optional sections for parking brake output performance for rear brakes. It is applicable to brake corners from vehicles covered by the FMVSS 135 when using the appropriate brake hardware and test parameters. This procedure is applicable to all passenger cars and light trucks up to 3500 kg of GVWR.
Rationale
This Recommended Practice is the result of an industry effort to develop an inertia-dynamometer test procedure based upon the FMVSS 135 vehicle test. Results from this test provide a laboratory assessment of the brake corner performance. Data from this Recommended Practice may be combined with other brake system and vehicle characteristics to predict vehicle performance.
The conditions defined in this Recommended Practice are drawn from FMVSS 135 vehicle test experience. The deceleration levels are not necessarily based on those needed to meet the requirements of the FMVSS 135. This procedure is intended to properly represent the lining conditioning which occurs during an FMVSS 135 vehicle test.

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.
