Introduction

This standard outlines a method for determining the surface scratch resistance of ceramic products and glazes using the Mohs hardness test. It provides detailed procedures for preparing test samples, conducting the hardness test, and evaluating the results. The method is designed to ensure consistency and accuracy in measuring the scratch resistance of ceramic surfaces. The standard specifies the equipment, materials, and conditions required for the test, as well as the criteria for interpreting the test outcomes. It is intended for use by manufacturers, quality control laboratories, and other relevant parties involved in the production and testing of ceramic products.
