Road vehicles. Brake lining friction materials. Friction behaviour assessment for automotive brake systems Ingestion-build-264231 its design (material1 Scope This International Standard describes a test procedure for assessing the influence of pressure, temperature, and linear speed on the coefficient of friction of a given friction material in combination with a specific mating component (rotor or drum). This International Standard is intended for use when comparing friction materials under the same conditions, or when controlling friction behaviour against a specification or certain performance
