Road Vehicles - Friction Materials - Finished Brake Pad Normalized Elastic Constant of Friction Material
J3175_201911
This SAE standard specifies a method for testing and measuring a normalized elastic constant of brake pad assemblies using ultrasound. This document applies to disc brake pad assemblies and its coupons or segments used in road vehicles.
Rationale:
Measurement of variations in elastic properties because of raw materials, internal cracks, or other factors can be useful for quality control. Elastic properties are also important for lining characterization. The purpose of this test procedure is to evaluate the normalized elastic constant of friction material on a finished brake pad.
