This standard specifies the method of Paints and varnish scratch test, which is used to evaluate the scratch resistance performance of coatings under external force. The test uses a standardized scratch tool to apply a certain pressure on the coating surface to observe whether the coating is scratched, disbonded or Miscellaneous damage. The standard describes in detail the test equipment, sample preparation, test procedures and result evaluation criteria to ensure the standardization of the test process and the Reliability of the results. This test is mainly used for quality control and performance evaluation of coatings. It is widely used in automotive, home appliances, construction and other industries to help judge the abrasion resistance and durability of coatings. Through scratch testing, the performance of coatings in actual use can be predicted and the improvement and optimization of coating products can be guided.
