ASTM-F559 › Standard Test Method for Measuring Length of Road Test Courses Using a Fifth Wheel
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the accurate length measurement of road courses used for testing all types of pneumatic tires on various associated vehicles.
1.2 This test method is intended for use on public highways or closed circuit test courses, or both, that cannot be measured practically by surveying techniques.
1.3 Use of this test method requires that the surface of the test course to be measured shall be sufficiently smooth to preclude bounce or hop of the fifth wheel, which will affect the accuracy of the measurement. The normal highway surface is adequate for this test method.
1.4 It is not the intent or scope of this test method to encompass distance measurements of test courses whose surfaces are irregular, broken up, jagged, and so forth, such as rock courses, Belgian block, “rumble” surfaces, and the like. Snow- and ice-covered surfaces also are excluded.
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
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 and health 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.
Significance and Use
5.1 Maps, automobile odometers, and highway and distance markers are not sufficiently accurate to describe the length of a route for tire testing purposes. The proposed procedure describes a test method for measuring the length of a road course with sufficient accuracy for tire testing purposes.
