Meaning and Purpose
4.1 Satisfactory execution of coatings requires adherence to the substrate on which they are applied. It has been found that the test method can be used to distinguish the degree of adhesion between the coating and the substrate. It is most applicable to provide a relative rating for a range of coated panels that exhibit significant differences in adhesion.

4.2 The study carried out in the laboratory using the circular stylus specified in the previous edition showed that it was not possible to obtain meaningful adhesion data when a load of 10 to 20 kg was required to destroy the surface of the solvent-based coating. When this level of load was required, the chrome ring stylus flashed and skipped over the coated surface. Similar meaningless data were obtained when testing powder coatings, requiring more than 10 kg to destroy the surface. Therefore, conducting the test under these conditions is not applicable.

ASTM D2197-2022 Adhesion of Organic Coatings

Scope of
1.1 The test method consists of determining the adhesion of organic coatings (such as paints, varnities, and varnities) when applied to the surface of a smooth, flat (flat) panel.

1.2 Values expressed in SI units shall be regarded as standards. The values given in parentheses are for reference only.

1.3 This standard is not intended to address all safety issues, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health and environmental practices and to determine the applicability of regulatory restrictions prior to use.

1.4 This international Standard has been developed in accordance with the internationally recognized standardization principles established in the Decision on Principles for the Development of International Standards, Guidelines and Recommendations issued by the Committee on Technical Barriers to Trade of the World Trade Organization.
