This specification covers the design and construction standards, material and physical requirements, and test methods for a smooth-tread standard tire for measuring tire-pavement friction forces. When tested with appropriate methods, the tread compounds shall conform to specified values of physical properties such as tensile sheet cure, 300 % modulus, specific gravity, tensile strength, elongation, and tire tread durometer performance.
1.1 This specification covers the general requirements for a smooth-tread standard tire for measuring tire-pavement friction forces.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
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.
