Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Introduction
In dentistry, colour matching, colour communication among dentist and dental technician (indirect
restorations) and colour reproduction and verification are essential elements for a successful aesthetic
restoration. Other important appearance attributes include translucency/opacity, gloss, opalescence
and fluorescence.
Questions regarding the principles of chromatics and the individual colour perception have been
controversially discussed for years between those involved. Today, various systems are available for the
purpose of objectivizing tooth colour perception. The most common method is the colour comparison
using reference colours being supplied in the form of shade guides consisting of tooth shaped colour
tabs made of ceramic, for a dental colour system. The objective of this document is to specify test
methods for such colour tabs. This document does not cover colour samples, which are produced by
each manufacturer to demonstrate colour effects usually of all components of a given individually
designed assortment. These colour samples are not used to determine the colour in vivo and are not
provided in a tooth-shaped form.
