ASTM D522 -Standard Testing Instruments

ASTM D522 is a specification that outlines the standard test procedures of the study on the flexibility and adhesion action of coated panels by carrying out mandrel bend testing. The standard assists manufacturers to research the resistance of the paints, varnishes, coatings, and surface finishes used on bending conditions to cracking, peeling off, and failure of the coating. It is widely used in coating, automotive, metal finishing, packaging, and industrial manufacturing sectors for coating quality inspection and durability evaluation. ASTM International Presto Laboratories offers precision conical mandrel bend tester systems suitable for ASTM D522 testing applications. These testing systems help industries study coating flexibility, surface durability, and adhesion performance under controlled laboratory testing conditions for quality verification and research requirements.
