This document specifies the nominal dimensions for surface profile features and patterns for the surfaces of pedestrian paving units, used to convey information for visually impaired people. It applies to paving units made of concrete, clay and stone.This document does not specify requirements for visibility (colour, luminance contrast or profile) except where this visibility is provided by the tactile paving surface indicator. It does not specify material characteristics.NOTE 1See Introduction for an explanation for the exclusion of luminance contrast requirements.NOTE 2A guide to the various applications of tactile surfaces in a number of European countries is given in informative Annex A.
