Scope
This procedure describes a method for generating, preparing and analyzing samples of new and unused brake friction materials for their chemical constituents.
Rationale
The states of Washington and California passed laws in 2011 restricting the amount of cadmium, copper, hexavalent chromium, lead and mercury their compounds in brake friction materials. As part of the legislation, brake friction materials are required to be analyzed to confirm the levels of the restricted elements are below the values stated in the legislation. The SAE J2975 provides a method on how to generate samples of brake friction material for analysis, how to prepare the samples for analysis and how to analyze the samples.
This revision expands the applicability of EPA method 3051A and EPA method 6010C (used in tandem) for mercury detection and measurement. These two methods combined eliminate the possible interference from copper and sulfides, which are common in friction materials. The revision also allows EPA method 6020A to be used for detection restricted substances.

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.
