The vocabulary is limited to those terms in general use throughout the rubber industry. It does not define terms intended for particular rubber products, some of which are given in the vocabulary standards listed in the Bibliography. It does not define terms that are generally understood or adequately defined in other readily available sources such as general dictionaries. The terms are listed in the alphabetical order of theEnglish terms, with a French index to the corre-sponding English terms attached. Some terms have parenthetical information added to indicate a specific limitation of the term to a particular field, for example “rubber latex”.When a term has one or more synonyms, the synonymous terms follow the preferred term. Deprecated terms are indicated by “(deprecated)”. The abbreviation “cf.” indicates that the user may refer to another term (not a synonym) which contains information on a closely related area. Symbols are included under their full descriptions, but for convenience they are also listed separately at the end of the main text. For convenience, standards and other relevant sources referred to in this vocabulary are listed in the first section of the Bibliography and vocabu-laries relating to finished rubber products are listed in the second section.
