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
