This part of ISO 10241 specifies requirements for the drafting and structuring of terminological entries in standards, exemplified by terminological entries in ISO and IEC documents. Terms and other designations occurring in terminological entries can include letters, numerals, mathematical symbols, typographical signs and syntactic signs (e.g. punctuation marks, hyphens, parentheses, square brackets and other connectors or delimiters), sometimes in character styles (i.e. fonts and bold, italic, bold italic or other style conventions) governed by language-, domain- or subject-specific conventions. Terms can also include standardized symbols (which can be language independent or internationally harmonized, such as symbols for quantities and units as well as graphical symbols) which are under the responsibility of different committees in ISO and IEC. This part of ISO 10241 is based on the principles and methods given in ISO 704 and provides rules for both monolingual and multilingual terminological entries in standards and their indexes. NOTE 1 Annex I of the IEC Supplement to the ISO/IEC Directives[1] for the work on the International Electrotechnical Vocabulary (IEV) is based on the standards prepared by ISO/TC 37. Due to specific requirements, the rules provided in this Supplement are sometimes different from the rules given in this part of ISO 10241. This part of ISO 10241 is applicable to all standards that contain terminological entries. It does not deal with the administrative procedures or the technical specifications required by standardizing bodies for the preparation of terminology standards. NOTE 2 Administrative procedures for the preparation of standards are specific to the standardizing body. For example, in ISO and IEC these rules are provided in the ISO/IEC Directives, Part 1[2].
