The ASTM D 5179-2021 standard specifies a method for determining the adhesion of organic coatings on plastic substrates by a direct pull test. This test measures adhesion by installing and removing metal studs on the coating surface and is suitable for plastics and Miscellaneous substrates. This method is used for comparison of coating adhesion under laboratory conditions. The standard does not cover all safety issues. Users need to confirm their own safety and health practices.
