DIN EN 14157 is a standard for natural Stone abrasion resistance testing methods developed by the European Organization for Standardization CEN. The standard specifies a variety of test methods, including the Taber abrasion method, the Pin-on-Disk method, and the Los Angeles abrasion method, among others. The Taber abrasion method is a commonly used test method that evaluates the abrasion resistance of Stone by using two swirl/spin grinding wheels on the surface of Stone. The Pin-on-Disk rule evaluates the abrasion resistance of Stone by using a swirl/spin steel ball on the surface of Stone for abrasion. Los Angeles abrasion laws evaluate the abrasion resistance of a stone by adding specific sand, gravel and water to it in a swirl/spin steel cylinder. These test methods are applicable to various types of natural Stone, including Granite, Marble, Limestone, etc. By using these standard methods, reliable abrasion resistance testing data can be obtained to provide reference for the design, production and use of Stone. It is important to note that these standard methods provide only one test method and do not fully evaluate the abrasion resistance of Stone. Therefore, when using these standard methods, a comprehensive assessment is required in combination with Miscellaneous factors, such as the use case of Stone, life expectancy, etc. In addition, the standard has been revised in 2020 to cover more testing details and requirements.
