Trailer Standard for Road Roughness Measurement (Withdrawn 2024) by ASTM International

This standard outlines the design, performance, and operational aspects of trailers used to measure vehicular response to road roughness. It does not cover the instrumentation for sensing trailer movements. The trailer in question is a two-wheeled, single-axle vehicle, towed on highways at typical speeds, with relative axle-body movement transduced and recorded as an indicator of road roughness.

• Trailer Design & Functionality: This specification outlines the design, performance, and operating features of a trailer used for measuring road roughness response
• Trailer Type & Operation: The specified trailer is a two-wheeled, single-axle vehicle, towed on highways at typical speeds, recording relative axle-body movement for road roughness indication
• Instrumentation Exclusion: This specification does not cover the instrumentation for sensing trailer movements
• Instrumentation Example: One example of instrumentation is detailed in Test Method E1082
• Standard Units: Values stated in inch-pound units are considered the standard
• Safety Responsibility: This standard does not cover all safety concerns; users must establish safety practices and determine regulatory applicability
• Standard Development: This international standard was developed following WTO TBT Committee's internationally recognized standardization principles
