本标准规定了用于牙科修复的合成树脂牙和陶瓷牙的分类、要求和试验方法。
本标准规定了用于牙科的石膏产品的分类及性能要求、相关要求的试验方法、包装标识和使用说明书的要求。本标准适用于制作口腔印模、模型、铸造模型、代型或模型底座以及用于固定模型的石膏产品。本标准不适用于由半水硫酸钙(或石膏)组成的牙科骨替代物。
本标准适用于牙科铸造蜡和牙科基托蜡。本标准规定了牙科铸造蜡和牙科基托蜡的分类和要求,以及相应的试验方法以确定被试样品是否符合本标准的要求。
本标准规定了牙科复制材料的要求和试验方法、该复制材料主要用于制作从适当倒凹封闭的母模型翻制耐火包埋阳模所需的柔韧的模腔。
本标准规定了用于永久封闭牙根管的牙科根管封闭材料的性能要求和试验方法。牙科根管封闭材料可以在潮湿或无潮湿环境下固化,可以结合牙根管根尖充填尖使用或单独使用。本标准仅适用于正向充填的牙根管封闭材料,即从牙齿冠部进行根管充填。不固化的牙科根管封闭材料不适用于本标准。
本标准对应用于牙科的聚合物基代型材料的组成、性能、使用说明、包装、标识以及测试要求进行了规定。本标准适用于以聚合物基质为主要组成的代型材料。聚合物基代型材料主要用于牙科技工室从印模翻制制作活动或固定修复体的模型(铸模)。
本标准规定了弹性含水琼脂和藻酸盐水胶体牙科印模材料的性能要求和试验方法,以便确定其能否达到预期的使用质量。同时规定了使用说明书和标签的要求。本标准适用于弹性含水琼脂和藻酸盐水胶体牙科印模材料。
本标准对主要用于制作义齿的由天然腊和合成蜡组成的牙科基托/模型蜡的分类和要求进行了规定,并规定了相应的试验方法以确定被试样品是否符合本标准的要求。

This International Standard gives a classification of, and specifies requirements for, gypsum products used for dental purposes such as for making oral impressions, models, casts or dies. It also specifies the test methods to be employed to deter-mine compliance with these requirements.
This European Standard specifies general requirements for materials used in the practice of dentistry for the restoration of the form and function of the dentition and which are medical devices. For the purposes of this standard these materials are defined as restorative materials. Dental implants are specifically excluded and described in EN 1642. This standard includes requirements for intended performance, design attributes, components, sterilization, packaging, marking, labelling, and information supplied by the manufacturer.Tests for demonstrating compliance with this standard are contained in the level 3 standards, if appropriate.
This document specifies requirements and test methods for root canal sealing materials which set with and without the assistance of moisture and are used for permanent obturation of the root canal, with or without the aid of obturating points. It is applicable only to sealers intended for orthograde use, i.e. a root filling placed from the coronal aspect of a tooth.
This International Standard specifies test methods for the assessment of the accuracy of digitizing devices for computer-aided design/computer-aided manufacturing (CAD/CAM) systems for indirect dental restorations. These test methods are not applicable to digitization by radiographic methods (X-ray) and by magnetic resonance imaging methods (MRI).
This International Standard gives requirements and test methods for determining the compliance of dental casting investment, dental brazing investment, dental pressable-ceramic investment and dental refractory die materials used in the dental laboratory, regardless of the composition of the refractory powder, the composition of the binder, or the particular application. This International Standard classifies such products into types and classes, according to their intended use and the burn-out procedure recommended by the manufacturer. It also gives requirements for marking, labelling and manufacturer's instructions. It specifies requirements for the essential physical and mechanical properties of the products and the test methods to be used for determining them.
This International Standard gives a classification of, and specifies requirements for, gypsum products used for dental purposes such as making oral impressions, moulds, casts, dies or model bases, and mounting models. It specifies the test methods to be e
