ISO FDIS 1519-2010 《Paints and varnishes. Bend test (cylindrical mandrel)》 Related products

This standard specifies the method of Paints and varnish bend testing, using cylindrical mandrel as a test tool to evaluate the flexibility and adhesion of coatings when bent and deformed. The test is performed by bending the coating sample around the cylindrical mandrel to observe whether the coating is crazing, flaking or Miscellaneous damage. The standard describes in detail the test equipment, sample preparation, operation procedures and evaluation criteria for the results to ensure the conformity and Reliability of the test results. This test is mainly used for quality control and performance verification of coating products, especially for automotive, home appliances, construction and other industries, to help manufacturers evaluate the bending performance and durability of coatings in actual use. Through this test, the bending adaptability and damage resistance of coatings can be scientifically evaluated, providing an important basis for the improvement and optimization of coatings.
