GB/T 16534-2009 "Test Method for Room Temperature Hardness of Fine Ceramics" stipulates the test method for room temperature Hardness of fine ceramics. The standard specifies the test principle, equipment requirements, sample preparation, test steps and result calculation, etc., and is suitable for the determination of room temperature Hardness of whole fine ceramics. Through a unified and standardized test process, the Hardness characteristics of fine ceramics at room temperature can be accurately evaluated, providing a reliable detection basis for the research and development, production and mass control of fine ceramics, and promoting the technical development and mass improvement in this field.
