SAE J 380-2017
Specific Gravity of Friction Material
SAE J380-2017 发布历史
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. Purpose??To establish a uniform procedure for determining the specific gravity of brake friction material.
