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

1.2These 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.

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

1.4The 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.

1.5This 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.
