The NF T30-038-2020 standard specifies a method for evaluating the adhesion of Paints and varnish coatings by a cross-cut test. This test cuts out a series of parallel lines on the surface of the coating and intersects them with another set of parallel lines to form a grid, which is then pasted and quickly torn off using adhesive tape to observe the coating disbonding. According to the degree of disbonding, the adhesion is divided into different grades. This method is suitable for laboratory and field use to help evaluate the performance of coatings in practical applications.
