Scope

1.1 This test method covers the calibration of the force (or torque) transducer and associated instrumentation of a mounted test wheel by using a calibration platform. 1.2 This test method is a static calibration, simulating the traction force between a tire and the pavement. 1.3 In the case of a force-measuring system, the instrumentation readout is directly proportional to the calibration force input. 1.4 In the case of a torque-measuring system, the instrumentation readout is a measure of the calibration force input and the effective tire radius. 1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.6 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. 1.7 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.
