This standard specifies the test method for Paints and varnish in the T bend test to evaluate the durability and adhesion of coatings subject to bending deformation. The test is to observe whether the coating is crazing, flaking or Miscellaneous damage by applying bending stress to the surface of the substrate. The standard specifies the test equipment, sample preparation, test procedures and the evaluation method of the results to ensure the Reliability and repeatability of the test results. The test is mainly used for quality control and performance evaluation of coating products, especially for coating applications in the automotive, construction and home appliance industries. Through this test, manufacturers can ensure that the coating has sufficient flexibility and damage resistance in practical use.
