To the various criteria such as durability and comfort, always taken into account for the purchase of a vehicle, nowadays criteria of sensory size like smell and touch are to be added. We carried out this study on evaluation of touch of plastics surfaces as these materials are largely used in automobile cockpits. The touch of these materials must first be evaluated in order to be controlled. It is the role of the panels of skilled experts, who use various tactile descriptors to characterize surfaces according to human sensitivity. The objective of this work is to undergo a statistical analysis of tactile data on the basis of precise criteria (repeatability, consistency, precision of analysis) in order to achieve a characteristic model of a given descriptor, selected for the tactile sensory analysis.
