Formerly under the jurisdiction of Committee E17 on Vehicle-Pavement Systems, this test method was withdrawn in May 2024. This standard is being withdrawn without replacement due to its limited use by industry.

4.1 This test method provides a means of evaluating traveled surface roughness. The measured values represent vehicular response to traveled surface roughness obtained with the equipment and procedures stated herein and do not necessarily agree or correlate directly with those obtained by other methods.3

1.1 This test method covers the determination of vehicular response to traveled surface roughness.

1.2 This test method utilizes an apparatus that measures the relative motion of a sprung mass system in response to traveled surface roughness where the mass is supported by automotive-type suspension and tires.

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. Specific precautionary statements are given in Section 6.

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.
