What is ASTM standard for pull-off test?

Share:
The ASTM standard for pull-off test is ASTM D4541-22: Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers. This standard specifies the procedure for evaluating the pull-off strength, also known as adhesion, of a coating system from metal substrates using portable adhesion testers. The test method described in ASTM D4541-22 is commonly used to assess the adhesion of coatings in various industries.
It's important to note that previous versions of ASTM D4541 included a Test Method A, which was used for testing concrete substrates. However, Test Method A has been eliminated, and for testing the adhesion of coatings on concrete, ASTM D7234-21: Standard Test Method for Pull-Off Adhesion Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers should be referred to.
The pull-off test, as described in ASTM D4541-22, involves attaching a test dolly to the coated surface using an adhesive and applying a gradually increasing load until the dolly is pulled off. The force required to pull off the dolly or the force the dolly withstood is measured and used to determine the pull-off strength of the coating system.
