This document specifies the requirements for resin-modified dental adhesives used for bonding, underlayment or lining, restoration, and fabrication of dental posts and cores, and describes the corresponding test methods. This document applies to resin-modified water-based dental adhesives that are cured through a combination of various reactions, including acid-base reactions and polymerization reactions. For example, traditional polyacrylic acid-based glass ionomer dental adhesives are typically produced by the reaction of an ion-releasing aluminosilicate glass with polyacrylic acid in a water environment. The adhesives covered in this document can typically be cured either through water-based acid-base reactions or polymerization reactions. Note: Manufacturers and testing institutions should pay attention to the closely related international standards ISO 4049 (YY 1042-2023/ISO 4049:2019, MOD) and ISO 9917-1 (YY 0271.1-2016/ISO 9917-1:2007, MOD).
