客车,卡车和大客车轮胎滚动阻力的测量方法.单点测试和测量结果的相关性

[中文适用范围]： 本文件规定了在受控实验室条件下测量主要用于客车、卡车和公共汽车的新型充气轮胎滚动阻力的方法。 本文件不适用于仅供临时使用的轮胎。 它包括一种关联测量结果以允许实验室间比较的方法。 它旨在促进国际合作，并可能促进监管建设。 使用这种方法测量轮胎可以对新测试轮胎在垂直于鼓外表面的位置和稳态条件下直线向前自由滚动时的滚动阻力进行比较。 [外文原描述]： 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.
