Product Code:SAE J379
Title:Gogan Hardness of Brake Lining
Issuing Committee:Brake Linings Standards Committee
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.【英文标准名称】:StandardSpecificationforJointsforCircularConcreteSewerandCulvertPipe,UsingRubberGaskets
