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, .

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).
