The ASTM D4228-05 (2023) standard provides a method of verifying the ability of coating builders to apply specific coatings to steel surfaces. The standard requires coating builders to provide the necessary coating materials and equipment and to demonstrate their ability to use appropriate technology and equipment. Assessments are performed by qualified agencies to ensure that coating masses meet specified requirements. The standard applies to all occasions where verification of coating builder skills is required, particularly including safety-related areas in nuclear facilities. Users are required to establish appropriate safety practices and follow relevant regulations.
