3 Configuration of the designation
The designation code includes ten symbols for the designation of dimensions and other characteristics of the tool holder and the indexable insert. In addition to the standardized designation (symbols 1 to 10), a supplementary symbol consisting of a maximum of three letters and/or numbers may be added by the manufacturer for a better description of his/her products on condition that this symbol is separated from the standardized designation by a hyphen. No addition to or extension of the code given in this International Standard shall be made without consultation with ISO/TC 29 and without its agreement. Rather than adding symbols not provided for in this system, all necessary explanations should be added in detailed sketches or specifications to the designation conforming to this International Standard.
