GB/T 3849.1-2015 Test method for focusing hard alloy rockwell hardness (A scale). It clarifies the test principle, specifies the scope of application, and puts forward clear requirements for the accuracy of the test equipment and the specifications of the indenter. The preparation specification of the sample is described in detail, covering dimensions, surface roughness, etc. The standard also describes the test operation process in detail, including the application, holding and removal of the test force, as well as the measurement and calculation method of the Hardness value. With this standard, the rockwell hardness (A scale) of hard alloys can be accurately determined, providing a reliable basis for quality control and performance evaluation.
