Scope
This standard specifies the performance requirements and test methods for dental metal materials (manufactured by casting or machining) and ceramics used in the fabrication of dental metal porcelain restorations, as well as the performance requirements and test methods for metal-porcelain composites. The performance requirements of this standard apply to metal materials and ceramics used in combination, but not to metal materials or ceramics used separately.
