本国际标准规定了单人轻便摩托车的试验和测量方法（定义见ISO 3833） 配备一个或多个防抱死系统和一个或多个独立制动系统。其目的是建立 此类系统的全球统一测试程序。 本国际标准规定了以下类型直线制动试验的程序: ？附着力试验的利用； ？轮锁检查试验； ？ABS测试失败； ？可以帮助评估和开发制动系统的补充测试。 注:本国际标准中参考了L类车辆，通常指单人轻便摩托车（L1）， 根据联合国第78号条例和《关于车辆制造的综合决议》（R.E.3） 欧洲经济委员会（联合国欧洲经委会）。本国际标准中用方括号括起的数值来自 同一法规（02系列修正本）和包含在其中以供参考。

This International Standard specifies tests and measurement methods for solo mopeds (defined in ISO 3833) equipped with one or more antilock, and one or more independent, braking systems. Its purpose is to establish uniform worldwide test procedures for such systems. This International Standard sets out procedures for the following types of straight-line braking tests: ？ utilization-of-adhesion test; ？ wheel-lock check test; ？ tests with ABS failed; ？ complementary tests that could assist in the assessment and development of braking systems. NOTE Reference is made in this International Standard to L-category vehicles, generally referring to solo mopeds (L1), drawn from Regulation No. 78 and the Consolidated Resolution on the Construction of Vehicles (R.E.3) of the United Nations Economic Commission for Europe (UN-ECE). The values given in this International Standard enclosed by square brackets are from the same regulation (02 series of amendments), and are included for information.
