标准摘要
[中文适用范围]： 本部分 ISO 21069 规定了滚轮制动测试，用于确定 ISO 1176 中定义的最大授权总质量（代码 ISO-MO8）超过 3.5 t 的道路车辆的制动效率，属于 M2、M3、N2 类、N3、O3 和 O4 符合 UNECE RE3 中的定义，并配备全功率空气（气动）制动系统。 同样适用于电子制动系统 (EBS)，其目的是确保不同测试仪的测量结果具有可比性，从而无论在何处进行滚轮制动测试，都可以可靠地评估行车制动系统的效率。 [外文原描述]： ISO 21069-1:2004 specifies a roller brake test for determining the braking efficiency of road vehicles having a maximum authorized total mass (Code ISO-M08) as defined in ISO 1176 of more than 3,5 t, being of categories M2, M3, N2, N3, O3 and O4 as defined in UNECE R.E.3 and equipped with full power air (pneumatic) braking systems. Also applicable to electronic braking systems (EBS), its purpose is to ensure comparable measurement results from different testers, leading to reliable assessment of the efficiency of service braking systems wherever roller brake tests are performed.
