GB/T 41663-2022 Translated English of Chinese Standard (GB/T 41663-2022, GBT41663-2022): Road vehicles - Brake lining friction materials - Scale inertia dynamometer test methodThis document specifies the test conditions and preparation, specimen items and procedures, and test reports of the scale inertia dynamometer test method for the brake lining friction materials of road vehicles. This document is applicable to the scale inertia dynamometer test of disc brake linings of passenger cars. On the basis of familiarity with the principle of scale reduction, this document may also be taken as a reference for the brake lining test of other types of vehicles. This document is applicable to raw material screening and inspection, early development of friction materials, quality control of production processes and test of foreign samples. |
