Scope
Provide description of standard test methods, analysis methods, and reporting methods for measuring the resonant modes of automotive disc brake rotors and drums for purpose of design and production verification of these components.
Rationale
Braking systems industry uses modal testing of brake rotors for design validation, production validation, and quality control purposes. Several vendors provide equipment to facilitate this measurement. Currently, there exists no standard procedure that brings uniformity to these measurements. This procedure addresses this need by providing the guidelines necessary for making these measurements comparable.

* 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.
