1 Scope
This standard gives guidance on substrate selection, storage and handling as well as essential characteristics of different test methods for quality testing of the adhesive bond between restorative dental materials and tooth structure, i.e. enamel and dentine. It specifies two bond strength measurements tests (tensile and shear), a test for measurement of marginal gaps around fillings and a microleakage test. It also presents some specific test methods for bond strength measurements.
