This International Standard specifies graphical symbols for dental equipment. It is intended that the symbols are to be used on the appropriate piece of dental equipment and in documents pertaining to dental equipment, for example in instructions for use, marking, labelling, and technical product documentation. The symbols are selected specifically for all kinds of dental equipment. The majority of the symbols are taken from relevant ISO, IEC, or other international documents. Several new symbols presented by manufacturers or users have been added. NOTE – In addition to terms used in two of the three official ISO languages (English, French, and Russian), this International Standard gives the equivalent terms in the German language; these are published under the responsibility of the member body for Germany (DIN). However, only the terms given in the official languages can be considered as ISO terms.
