GB/T 5766-2007 is a test standard for rockwell hardness of friction materials. Rockwell hardness is essential to measure the performance of friction materials and ensure that they work reliably in scenarios such as braking. The standard specifies the scope of friction materials applicable to the test, specifies the main points of specimen preparation, including size, Smoothness and other requirements. Specifies the selection, installation and calibrating of Rockwell hardness testers. Describes the test process, covering key steps such as test force application, maintenance and reading. Specifies the calculation and representation of results. The standard provides a basis for accurately determining the rockwell hardness of friction materials, and helps manufacturers control the mass of products and ensure the actual performance of friction materials.
