scope:

Specifies tests and measurement methods for brakes and braking of mopeds with two or three wheels, as defined in ISO 3833, which are intended for use on public roads, in order to establish uniform worldwide test procedures for braking systems. Further complementary tests which may assist in the assessment and development of braking systems are also included. Reference is made to "L-category" vehicles. UN-ECE Regulation No. 78 defines a two-wheeled moped (L1) and a three-wheeled moped (L2). This standard does not cover mopeds which are - controlled by a pedestrian; - designed for the special use of handicapped persons. This standard sets out the following types of tests: - static tests; - dynamic tests: basic tests, wet brake tests, heat fade tests; - parking brake tests (where applicable).
