Specific Gravity of Friction Material

Scope
Specific gravity is a nondestructive test used as a quality control check of the consistency of formulation and processing of brake lining. The specific gravity and the range of specific gravity are peculiar to each formulation and, therefore, the acceptable values or range must be established for each formulation by the manufacturer. Specific gravity alone shows nothing about a materials in use performance.
The specific gravity of sintered metal powder friction materials, particularly those which have steel backing members, is usually determined somewhat differently. Reference ASTM B 376.
Rationale
This technical report is being Stabilized because it covers technology, products, or processes which are mature and not likely to change in the foreseeable future.

Issuing Committee
Brake Linings Standards Committee
The goal of the Brake Lining Standards Committee is to provide a means of developing and maintaining common test and nomenclature standards for the friction materials industry. In working toward this goal, the committee helps reduce industry costs, harmonize global markets and enhance safety by recommending uniform test and performance standards for automotive friction materials.

* 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.
