ASTM International Standard Specification for Trailers Used for Measuring Vehicular Response to Road Roughness ASTM E1215-93(2007)

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.
