- Features
- Issuing Committee
- Content
- 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.
- Content
- 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).
