GOGAN HARDNESS OF BRAKE LINING

Scope
Gogan hardness, a nondestructive (a penetrator causes shallow surface deformation) method of measuring compressibility, is used as a quality control check of the consistency of formulation and processing of brake lining. Gogan hardness alone shows nothing about a lining's ability to develop friction or to resist fade when used as a friction element in brakes. Gogan hardness varies with formulation, contour, and thickness of the lining.
The Gogan hardness and the range of Gogan hardness are peculiar to each formulation, thickness, and contour and, therefore, the acceptable values or range must be established for each formulation and part configuration by the manufacturer.

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.
