1 Scope
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.

3 Terms and definitions
For the purposes of this International Standard, the following terms and definitions apply. 3.1 category L1 two-wheeled vehicle with engine capacity not exceeding 50 cm 3 and design speed not exceeding 50 km/h 3.2 antilock system component of service braking system which automatically controls the slip ratio, in the direction of wheel rotation, on one or both of the moped’s wheels during braking 3.3 sensor component designed to identify and transmit to the controller conditions of rotation of the wheels or other dynamic conditions of the moped 3.4 controller component designed to evaluate and operate on data transmitted by a sensor and transmit signals to the modulator 3.5 modulator component designed to vary braking force in accordance with the signal received from the controller 3.6 outrigger equipment intended to limit the moped roll angle to a pre-set value 3.7 wheel lock condition that occurs when there is a slip ratio of 1 ,00 NOTE In practice, wheel lock is judged to have occurred when moped speed exceeds 1 5 km/h while wheel speed falls below 5 km/h. 3.8 braking system combination of parts (excluding engine) consisting of control, transmission(s) and brake(s) which progressively reduce or otherwise control the speed of a moving moped, halt it, and keep it stationary if already stopped 3.9 control part operated directly by the rider to supply to the transmission the energy required for braking or controlling the moped 3.10 transmission combination of components providing the functional link between the control and the brake 3.11 brake part of the braking system in which the forces opposing the movement of the moped are developed 3.12 independent braking system system acting on only one wheel 3.13 laden moped moped laden so that it reaches its “manufacturer’s maximum total mass”, as defined by ISO 6726, including the mass of the rider and test equipment, with the mass distribution on the axles as stated by the moped manufacturer NOTE See 5.2 and 5.3 for a description of the mass of the rider and of the test equipment. 3.14 unladen moped moped in the condition “vehicle kerb mass”, as defined by ISO 6726, with the mass of the rider and test equipment added NOTE See 5.2 and 5.3 for a description of the mass of the rider and of the test equipment. 3.15 maximum speed v max speed the moped can attain when tested in accordance with ISO 71 1 6 3.16 test speed moped speed measured at the moment the rider begins to actuate braking system control or controls
