本文件规定了由陶瓷材料制成的牙齿状颜色表示的要求，这些陶瓷材料用于确定患者口腔中的牙齿颜色或检查牙齿修复体的颜色，在本文件中称为颜色标签。 颜色标签的颜色坐标由制造商自行决定。 用于可视化陶瓷和其他块体颜色的资源，例如某些陶瓷和其他块体的块体阴影指南和颜色图案，不属于本文件的范围。它们可以由任何材料制成，仅用于说明颜色效果；它们不能决定口腔内的颜色。

This document specifies requirements for tooth-like colour representations made of ceramic materials used to determine the tooth colour in the patient's mouth or to check the colour of dental prosthesis, which are referred to as colour tabs in this document. The colour coordinates of colour tabs are left to the manufacturers' discretion. Resources for visualizing the colours of ceramic and other masses, e.g. mass shade guides and colour patterns for certain ceramic and other masses, do not fall into the scope of this document. They can be manufactured from any materials and serve solely to illustrate the colour effect; they do not serve to determine colour inside the mouth.
