GB/T 3398.1-2008 focused plastic Hardness determination, this part adopts ball indentation method. Plastics are widely used, and Hardness is related to their actual performance. The standard defines the applicable plastic types and elaborates the principle of ball indentation method. It clearly stipulates the requirements of test instruments, such as indenter size, loading device accuracy, etc., and calibrate specifications. Explain the sample preparation, including shape, size, surface state, etc. Strictly standardize the test operation, covering details such as loading force size, loading time, measurement point selection, etc. The Hardness value calculation and result representation method are given to provide a reliable basis for the accurate determination of plastic Hardness, and help the mass control and application design of plastic products.
