Dentistry. Adhesion. Notched-edge shear bond strength test PAS 015 and ampere squared hours (A²h)1 Scope This International Standard specifies a shear test method used to determine the adhesive bond strength between direct dental restorative materials and tooth structure, e. g. dentine or enamel. The method as described is principally intended for dental adhesives. The method includes substrate selection, storage and handling of tooth structure, as well as the procedure for testing. NOTE 1 Testing adhesion to tooth structure is technique
