Scope
This procedure is applicable to brake pad modes between 500 Hz. and 16 kHz. The parameters measured with this procedure are defined as the first three natural frequencies, fn (n=1, 2, 3), and the corresponding loss factors, η.
Rationale
The SAE Brake NVH Standards Committee reviewed the SAE J2598 standard and agreed that:
-
- No modification is required in the measurement requirements/test configuration sections.
-
- Additional methods to calculate the damping factor should be added to the standard (Chapter 9).

* 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.
