Dentistry - Base polymers - Part 1 : denture base polymers

ISO 20795-1:2008 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.ISO 20795-1:2008 applies to denture base polymers such as those listed below:poly(acrylic acid esters);poly(substituted acrylic acid esters);poly(vinyl esters);polystyrene;rubber modified poly(methacrylic acid esters);polycarbonates;polysulfones;poly(dimethacrylic acid esters);polyacetals (polyoxymethylene);copolymers or mixtures of the polymers listed above.

Dentistry - Denture base polymers

Bien que la présente Norme internationale n'exige pas, de la part des fabricants, une déclaration des détails de la composition, l'attention est attirée sur le fait que certaines autorités nationales ou internationales demandent que de tels détails leur soient fournis.La présente Norme internationale s'applique aux polymères pour base de prothèses dentaires tels que ceux qui sont énumérés ci-après.a) Poly(esters d'acide acrylique);b) poly(esters d'acide acrylique substitués);c) poly(esters de vinyle);d) polystyrène;e) élastomère modifié de poly(esters d'acide méthacrylique);f) polycarbonates;g) polysulfures;h) poly(esters d'acide diméthacrylique);i) polyacétals (polyoxyméthylène);j) copolymères ou mélanges des polymères énumérés de a) à i).
