标准摘要
[中文适用范围]： ISO 20795 的本部分对义齿基托聚合物和共聚物进行了分类，并规定了其要求。本部分还规定了用于确定是否符合这些要求的测试方法。此外，本部分还规定了产品包装和标记的要求，以及这些材料使用说明的要求。此外，本部分还适用于制造商声称其材料具有更高抗冲击性的义齿基托聚合物。本部分还规定了相应的要求和测试方法。 [外文原描述]： ISO 20795-1:2013 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 20795-1:2013 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 in 1 to 9.
