ISO/PAS 13473-6:2021 PDF Download

ISO/PAS 13473-6:2021 is a standard that outlines procedures for verifying the performance of laser profilometers used for measuring pavement texture. The standard aims to provide an internationally accepted method for evaluating the capability of laser-based equipment in accurately measuring pavement texture. It includes guidelines and recommendations to assist users in verifying the performance of their laser profilometers.

The document specifies that the procedure is not intended for qualifying or approving laser profilometers, but rather to ensure that these systems perform satisfactorily in all aspects important for accurate texture measurements. It also provides information about the limitations and trade-offs associated with laser profilometer systems.

While the standard focuses on contactless profilometers designed for two- or three-dimensional measurements, it acknowledges that some other contactless types of profilometers can utilize applicable parts of ISO 13473.

The motivation behind developing this standard is to address discrepancies in measurement results obtained from different equipment, even if operators claim to comply with ISO 13473. The standard is solely intended for pavement texture measurement and includes a reference program code, digital profiles, and calculated reference MPD-values in Annex A to eliminate errors influenced by programming mistakes or misinterpretation of ISO 13473-1.
