标准摘要
[中文适用范围]： 本国际标准规定了两种在负载条件下测量乘用车新轮胎滚动周长和每单位距离（公里）转数的方法。 第一种是鼓式方法，包括将安装在自由轴上的测试轮胎加载到指定直径的从动车轮或鼓上。 第二个涉及使用驱动桥配备测试轮胎的车辆在笔直的铺砌道路上行驶。 本国际标准适用于所有乘用车轮胎。 然而，从测量中获得的值并不旨在用作性能或质量的基准。 [外文原描述]： This International Standard specifies two methods for measuring, under loaded conditions, the rolling circumference and revolutions per unit distance (kilometres) of new tyres for use on passenger cars. The first is a drum method that consists of loading a test tyre mounted on a free axle against a driven road wheel, or drum, of specified diameter. The second involves using a vehicle whose drive axle is equipped with the test tyres driven on a straight, paved road. This International Standard is applicable to all passenger car tyres. However, the values obtained from the measurements are not intended to be used as benchmarks for performance or quality.
