Symbols and abbreviated terms

(The full requirements are described in the ISO/IEC Directives Part 2:2011, 6.3.2)


This conditional element lists the symbols and abbreviated terms used in the document.


Listing these symbols and abbreviations improves the understanding of the text and is convenient for the user.


It may be combined with the terms and definitions clause in order to bring together terms and their definitions, symbols, abbreviated terms and possibly units. In this case, an appropriate title could be “Terms, definitions, symbols, units and abbreviated terms”.
