The ASTM D7027-20 standard test method evaluates the scratch resistance of polymer coatings and plastics by using an instrument scratch machine. This method simulates scratching conditions that may occur in actual use by controlling specific loads, speeds, and scratch depths, and measures the damage resistance performance exhibited by the material during the scratch process. Tests can quantitatively evaluate the depth, width, and Miscellaneous surface changes of scratches, thus providing a reliable scientific basis for the scratch resistance of polymer coatings and plastic materials. The standard is widely used in automotive, electronic products, building materials, and other fields to ensure that the surface of the product has sufficient abrasion resistance and durability in daily use.
