Formerly under the jurisdiction of Committee E17 on Vehicle-Pavement Systems, this specification was withdrawn in May 2024. This standard is being withdrawn without replacement due to its limited use by industry.

This specification details the design, performance, and operating features of trailers used for measuring vehicular response to road roughness. The instrumentation for sensing the movements of the trailer is, however, not covered here. The trailer covered here is a two-wheeled, single-axle vehicle that is towed on highways at typical traffic speeds while the relative movement between the axle and body is transduced and recorded as an indication of road roughness.

1.1 This specification covers the design, performance, and operating features of a trailer used for measuring response to road roughness.

1.2 The specified trailer is a two-wheeled, single-axle vehicle that is towed on highways at typical traffic speeds while the relative movement between the axle and body is transduced and recorded as an indication of road roughness.

1.3 The instrumentation for sensing the movements of the trailer is not covered in this specification. One example of instrumentation is described in Test Method E1082.

1.4 The values stated in inch-pound units are to be regarded as the standard.

1.5 The following caveat pertains only to Section 5 of this specification: 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.

1.6 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.
