DIN EN ISO 20795-1:2013-06

This part of the standard classifies denture base polymers and copolymers and specifies their requirements. It also specifies the test methods to be used in determining compliance with these requirements. It further specifies requirements with respect to packaging and marking the products and to the instructions to be supplied for use of these materials. Furthermore, it applies to denture base polymers for which the manufacturer claims that the material has improved impact resistance. It also specifies the respective requirement and the test method to be used. This standard is applicable to denture base polymers such as those listed below: a) poly(acrylic acid esters) b) poly(substituted acrylic acid esters) c) poly(vinyl esters) d) polystyrene e) rubber modified poly(methacrylic acid esters) f) polycarbonates g) polysulfones h) poly(dimethacrylic acid esters) i) polyacetals (polyoxymethylene) j) copolymers or mixtures of the polymers listed in a) to i). The International Standard has been prepared by ISO/TC 106/SC 2/WG 11 "Denture base polymers" (secretariat: SN, Norway), in collaboration with CEN/TC 55 "Dentistry" (secretariat: DIN). On the national level the responsible committee is Working Committee NA 014-00-02 AA "Künstliche Zähne" ("Artificial teeth") at NADENT.
