1.1 This terminology covers definitions of technical terms used in the rubber industry. Terms that are generally understood or adequately defined in other readily available sources are not included.

1.2 Definitions for terms that have been established by other bodies recognized as expert in the field will, after ballot approval, be inserted in this terminology without change, and the source of the definition will be identified. Exceptions to this rule will be where the meaning of the term as used in the rubber industry is different from the common meaning of the term.

1.3 Users of this terminology who require mathematical expressions for the time and temperature dependent physical properties of some terms found in this standard should refer to Guide D5992 and other standards listed under referenced documents. Selected terms from Guide D5992 may be found in Annex A1.

1.4 Although this terminology standard avoids the inclusion of jargon and archaic terms as much as possible, some terms have been retained for historical reasons.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
