ASTM F1923-98(2014)

Standard Test Method for Tires, Pneumatic, Low Speed, Off Highway

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).
SCOPE
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 and health practices and determine the applicability of regulatory limitations prior to use.

This standard is issued under the fixed designation F1923; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
INTRODUCTION
This ASTM Standard has been developed to replace ASTM Provisional Standard PS 86-97. The
Provisional Standard was approved so that the U.S. military and other government agencies could
continue to purchase tested and qualified tires, until F1923 had been approved. The provisional
standard replaced the government’s specification ZZ-T-1083, Federal Specification, Tires, Pneumatic,
Low Speed, Off Highway, under the former FederalTire Program.That program was discontinued and
is replaced by the U.S. Army Tank Automotive Command’s Cooperative Tire Qualification Program
(CTQP).Whilefulfillingthemilitary’scommercialandtacticalneeds,theCTQPwillcontinuetoserve
federal, state, and local agencies that want to purchase qualified tires using this test method.
This test method is designed to be used in conjunction with the Administrator’s Approval and
