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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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 Methods 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 and health practices and determine the applicability of regulatory limitations prior to use.
