DIN EN ISO 22674:2016-09

Alloys of metallic materials are most commonly used in prosthetics in dentistry today. Many crowns and bridges for fixed prostheses and support structures are made of metallic materials. This standard was created to further improve the very high quality and safety of these products. The International Standard has been prepared by ISO/TC 106/SC 2/WG 21 "Metallic materials" (secretariat: DIN) together with CEN/TC 55 "Dentistry" (secretariat: DIN). The responsible committee at DIN is Working Committee NA 014-00-17 AA "Metals" at NADENT. The standard specifies requirements and test methods for metallic materials for fixed and removable dental prostheses. Chemical composition, hazardous element limits, biocompatibility, mechanical properties, density, corrosion resistance, tarnish resistance, solidus and liquidus temperature and linear thermal expansion are described. Requirements for instructions for use, marking and labelling are also included in the standard.
