This International Standard describes 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 shade guides (colour rings) in this standard.
The coordinates of tooth colours in the colour space (colour coordinates) the specification of which is left
to the manufacturers’ discretion as well as the colour deviations of ceramic and other masses or materials
used in the manufacture of dental prosthesis do not fall into the scope of this standard.
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 International Standard.
They can be manufactured from any materials and serve solely to illustrate the colour effect; they do not
serve colour determination inside the mouth.
