NF EN ISO 15854, S91-261 (06/2023)

This document specifies the classification and requirements for waxes used for dental casting (including products intended for CAD/CAM milling) using the so-called "lost wax" technique and the preparation of dental base plates and test methods to be applied to determine compliance with these requirements. Solid polymer-based products (such as acrylics) for CAD/CAM work, as well as thermoplastic or photocurable resins used in additive processes, are not covered by this document. This document does not specify quantitative requirements specific to the elimination of biological hazards.
