The national standard "road vehicle brake lining friction material scale bench test method" was officially implemented.
February 1, 2023The national standard GB/T 41663-2022 "Road Vehicle Brake Lining Friction Material Scaling Bench Test Method" under the centralized management of the National Technical Committee for Standardization of Non-metallic Mineral Products and Products (SAC/TC406) was officially implemented.
The release and implementation of GB/T 41663-2022 "Road Vehicle Brake Lining Friction Material Scale Bench Test Method" can enable the industry to form a consistent test method and evaluation method for the quality control of friction material production process, which plays an important role in improving the quality of brake lining friction material products.
The content of the national standard is to propose a test method of the scaled inertia test bench, which can simulate the braking process of the car in a large range of driving speed, braking temperature, braking pressure or braking deceleration. The performance of the friction material is evaluated. The test method can better avoid the inconsistency and error of the manufacturing enterprise in the preparation of brake lining friction material samples, test process and test results. The scale-down bench test method has both.Bench testRepresentation, and again.Small sample test is fast and convenientcharacteristics, compared to the full-size assembly test,Higher test efficiency, also for the testing processReduced cost.
Scope of application:
►►This document specifies the test conditions and preparation, sample items and procedures, and test report of the road vehicle brake lining friction material reduction bench test method.
►►This document is applicable to the scale reduction bench test of disc brake linings of passenger cars. On the basis of familiarity with the scale reduction principle, the test of brake linings of other types of vehicles can also refer to this document.
►►This document is applicable to raw material screening and inspection, early development of friction materials, quality control of production process and testing of foreign samples.
