(Main)Passenger car, truck and bus tyre rolling resistance measurement method — Single point test and correlation of measurement results
Passenger car, truck and bus tyre rolling resistance measurement method — Single point test and correlation of measurement results
This document specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks and buses. This document is not applicable to tyres intended for temporary use only. It includes a method for correlating measurement results to allow inter-laboratory comparisons. It is designed to facilitate international cooperation and, possibly, regulation building. Measurement of tyres using this method enables comparisons to be made between the rolling resistance of new test tyres when they are free-rolling straight ahead, in a position perpendicular to the drum outer surface, and in steady-state conditions.
Méthode de mesure de la résistance au roulement des pneumatiques pour voitures particulières, camions et autobus — Essai à condition de mesure unique et corrélation des résultats de mesure
Le présent document prescrit des méthodes de mesure de la résistance au roulement, dans des conditions de laboratoire maîtrisées, pour des pneumatiques neufs conçus essentiellement pour être utilisés sur des voitures particulières, des camions et des autobus. Le présent document ne s'applique pas aux pneumatiques destinés à un usage temporaire. Il comporte une méthode de corrélation des résultats de mesure destinée à permettre les comparaisons inter laboratoires. Il est conçu pour faciliter la coopération internationale et, éventuellement l'élaboration de réglementations. Le mesurage de pneumatiques selon cette méthode permet d'établir des comparaisons entre la résistance au roulement de pneumatiques d'essai neufs lorsqu'ils roulent librement en ligne droite, dans une position perpendiculaire à la surface extérieure du tambour et dans des conditions stabilisées.

L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes
nationaux de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est
en général confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l'ISO participent également aux travaux.
L'ISO collabore étroitement avec la Commission électrotechnique internationale (IEC) en ce qui
concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à ses futures mises
à jour sont décrites dans les Directives ISO/IEC, Partie 1. Il convient en particulier de prendre note
des différents critères d'approbation requis pour les différents types de documents ISO. Le présent
document a été rédigé conformément aux règles rédactionnelles des Directives ISO/CEI, Partie 2 (voir
