Standard Specification for Special Purpose, Smooth–Tread Tire, Operated on Fixed Braking Slip Continuous Friction Measuring Equipment
This specification covers the design and construction standards, material and physical requirements, and test methods for a special purpose smooth-tread standard tire utilized on fixed braking slip continuous friction measuring equipment such as the runway friction tester, surface friction tester, or BV-11 skiddometer trailer 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 special purpose, smooth-tread standard tire for measuring tire-pavement friction forces. The tire is utilized on fixed braking slip continuous friction measuring equipment such as the Runway Friction Tester, Surface Friction Tester, or BV-11 Skiddometer Trailer.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
