NF A91-142-2018 specifies a method for quantitative measurement of metal and Miscellaneous inorganic coating adhesion by tensile test. The standard uses tensile testing to evaluate the adhesion between coatings and substrates, which can effectively determine the bonding performance of coatings under tensile action. It is widely used in the quality control of metal protective coatings and inorganic coatings. Through tensile testing, the wear resistance, corrosion resistance and other performance of coatings can be evaluated, thus ensuring their Stability and long-term protection in actual use. This test method provides a reliable technical basis for Coating manufacturers to help improve coating processes and increase product mass, and is widely used in automotive, construction and machinery fields.
