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.
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.
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.
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.
