1.1 This test method covers measurements for comparative tire strength and dimensional characteristics. This test method covers new and retreaded pneumatic tires, both tube and tubeless types, and flaps when applicable, for mounting on construction, earthmoving, mining and logging equipment, graders, mobile cranes, and similar vehicles operated at low speeds off the road. 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information 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. ====== Significance And Use ====== 4.1 This test method establishes a standard procedure of comparative testing, for tire strength and dimensional characteristics, for use under the Administrator's Cooperative Approved Tire List (CATL) ( 2 ) .
