This standard specifies the test method for determining the surface wear resistance of glazed ceramic tiles. The method involves placing a grinding medium composed of steel balls of different particle sizes, corundum abrasive, and deionized water on the glazed surface. The sample is subjected to rotational grinding at a specified speed. After reaching a preset number of rotations, the worn sample is visually compared with an unworn sample in a dedicated observation box. Based on the number of rotations corresponding to visible wear marks, the wear resistance is classified into six levels, ranging from 0 to 5. This test is significant for evaluating the durability of glazed tiles in various usage scenarios, such as flooring and wall applications, directly impacting the product's service life and appearance retention. The core equipment used in actual testing is the glazed tile wear resistance tester, which must meet key technical parameters, including a support disc rotation speed of 300 r/min and an eccentricity of 22.5 mm. Modern models are also equipped with automatic counting and shutdown functions, combined with an observation box featuring fluorescent lamps with a color temperature of 6000–6500 K, ensuring the accuracy and repeatability of test results.
