ASTM F2803-21

Standard Test Method for Evaluating Rim Slip Performance of Tires and Wheels

SIGNIFICANCE AND USE
5.1 This test method establishes a standard procedure of comparative testing, for driven wheel rim slip, between candidate tire group(s) and a control tire group. This test method is suitable for research and development purposes where tire and rim specimens are compared during a brief testing time period. They may not be suitable for regulatory or specification acceptance purposes because the values obtained may not necessarily agree or correlate, either in rank order or absolute value, with those obtained under other conditions (for example, different locations or different seasonal time periods on the same test course).
SCOPE
1.1 This test method is performed to determine the amount of rotational slip occurring at the tire/wheel interface while under heavy longitudinal load conditions.  
1.2 This test method is suitable for research and development purposes where tires are compared during a single series of tests. They may not be suitable for regulatory statutes or specification acceptance because the values obtained may not necessarily agree or correlate either in rank order or absolute performance level with those obtained under other environmental conditions on other surfaces or the same surface after additional use.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 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.  
1.5 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.

Control tires (sets) are used for adjustment of data sets generated from an evaluation program or the statistical procedures used
on data sets, or both, in order to offset or reduce variation in test results. They can also be used to improve the accuracy of candidate
