Road and airfield surface characteristics. Test methods - Determination of longitudinal unevenness indices1 Scope This document specifies the mathematical processing of digitized longitudinal profile measurements to produce evenness indices. The document describes the calculation procedure for the International Roughness Index (IRI), Root Mean Square (RMS) and Longitudinal Profile Variance (LPV) from three separate wavelength bands and the WLP and WLP from the Weighted Longitudinal Profile (WLP). The purpose of this document is to provide a standard

BS EN IEC 60747‑5‑5:2020 includes some technical changes with respect to BS EN 60747‑5‑5:2011+A1:2015

For type B sheets measuring 156 mm × 156 mm and larger
