1.1 These practices cover the calculation of profilograph response to longitudinal profiles of traveled surface roughness.

1.2 These practices utilize computer simulations to obtain profilograph responses, including surface sensing wheel (recording wheel) vertical displacement and reference platform wheels (supporting wheels) motions as a function of distance.

1.3 These practices present standard profilograph simulations for use in the calculations.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only and are not considered standard.

1.5 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.
