ISO 2409-1992 "Paints and varnishes cross-cut test"

The ISO 2409:1992 standard describes the cross-cut test method used to evaluate the resistance of coatings to detachment from the substrate. This test is performed by cutting a right-angled mesh on the coating to determine the detachment of the coating from the substrate after being cut. Although the test results are influenced by Coating adhesion, it is not a complete substitute for adhesion testing. This test is mainly used to test the adhesion strength and overall durability of the coating to ensure that the coating performs in actual use.
