1.1 This terminology primarily covers definitions for technical terms that occur in ASTM Committee F09 standards on the characteristics and performance of tires.

1.2 Definitions for terms that may also be used in other technologies, such as vehicle behavior, are worded to cover both areas.

1.3 When any definition in this terminology (that does not have the limiting phrase) is quoted out of context, editorially insert the limiting phrase in a tire after the dash following the term. This will properly limit the field of application of the term and definition.

1.4 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.
