The ASTM C1895-20 standard test method is used to determine the Mohs scratch hardness of materials. This method is used to scratch test the test material according to the mohs hardness series by using a set of mineral standard samples with known Hardness. The Hardness grade of a material is determined by the Hardness of the standard mineral that can draw marks on its surface. The mohs hardness of the material can be accurately evaluated by comparing the scratches produced by different minerals on the surface of the material. This test method is widely used in the Hardness detection of minerals, gemstones, ceramics, metals and Miscellaneous materials, especially for evaluating the Hardness of natural ores and gemstones. This method provides a simple and effective Hardness evaluation method for materials scientific research and practical applications.
