Passenger cars — Stopping distance at straight-line braking with ABS — Open-loop test method

Voitures particulières — Distance d'arrêt de freinage en ligne droite avec ABS — Méthode d'essai en boucle ouverte

Abstract / scope

This document specifies an open-loop test method to determine the stopping distance of a vehicle during a straight-line braking manoeuvre, with the anti-lock braking system (ABS) fully engaged. This document applies to passenger cars as defined in ISO 3833 and light trucks.

This document specifies a reference method and is especially designed to ensure high repeatability.
