BS EN ISO 9917-2:2017规定了通过酸碱反应和聚合作用实现凝固的水基牙科粘合剂的要求和试验方法。这些材料用于粘接、基底或衬里、修复和牙核构建。示例:常规玻璃聚烷酸酯水泥通常是通过在水环境中使可离子浸出的铝硅酸盐玻璃与聚烷酸反应形成的。本文件范围内的材料通常能够通过这种水性酸影响凝结- 碱型反应，但除此之外，还可以通过聚合进行固化。注意，制造商和测试实验室的注意力被吸引到密切相关的国际标准ISO 4049和ISO 1717-1，以便他们可以考虑哪一个是最合适的评估任何单个产品。交叉引用:ISO 6344-1:1998ISO 8601:2004 Ed 3ISO 3696:1987ISO 7491:2000 Ed 2ISO 1942ISO 13116:2014 Ed 1ISO 4049:2009ISO 3665:2011 Ed 3ISO 14356:2003 Ed 1（R08）ISO 7405:2008 Ed 2ISO 10993- 1:2009ISO 9917-1:2007 Ed 2购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS EN ISO 9917-2:2017 specifies requirements and test methods for water-based dental cements in which setting is achieved by a combination of an acid-base reaction and polymerization. The materials are intended for luting, base or lining, restoration and tooth core build up purposes.EXAMPLE Conventional glass polyalkenoate cements are normally formed by reacting an ion-leachable aluminosilicate glass with a polyalkenoic acid in an aqueous environment. Materials that fall within the scope of this document will normally be able to effect setting by such an aqueous acid-base type reaction but in addition will be able to undergo setting by polymerization.NOTE The attention of manufacturers and test laboratories is drawn to the closely-related International Standards ISO 4049 and ISO 9917-1 so that they can consider which is the most appropriate for evaluating any individual product.Cross References:ISO 6344-1:1998ISO 8601:2004 Ed 3ISO 3696:1987ISO 7491:2000 Ed 2ISO 1942ISO 13116:2014 ED1ISO 4049:2009ISO 3665:2011 Ed 3ISO 14356:2003 Ed 1 (R08)ISO 7405:2008 Ed 2ISO 10993-1:2009ISO 9917-1:2007 Ed 2All current amendments available at time of purchase are included with the purchase of this document.
