本标准规定了通过铸造或机加工加工的牙科金属材料和适用于制造金属陶瓷牙科修复体的陶瓷的要求和试验方法，以及复合结构的要求和试验方法。本标准的要求适用于结合使用的金属材料和陶瓷，金属材料或陶瓷均不符合本标准的要求。本次修订基本上采用了ISO:9693，金属-陶瓷牙科修复系统，仅做了少量编辑性修改。

This standard specifies requirements and test methods for dental metallic materials processed by casting or machining, and for ceramics suitable for use in the fabrication of metal-ceramic dental restorations, together with requirements and test methods for the composite structure. The requirements of this standard apply to the metallic materials and ceramics when used in combination, and compliance may not be claimed for either metallic materials or for ceramics alone. This revision is essentially an adoption of ISO: 9693, Metal-Ceramic Dental Restorative Systems with minor editorial changes.
