1 Scope
This International Standard specifies tests and measurement methods for service brake systems and, where applicable, associated parking brake systems of two-wheeled mopeds (3-1) and three-wheeled mopeds (3-2) which are intended for use on public roads, in order to establish uniform worldwide test procedures for braking systems.
This International Standard does not cover mopeds which:
-
— have a maximum speed of less than 25 km/h;
-
— are equipped for disabled riders.
This International Standard sets out the following types of tests:
-
— dynamic tests:
-
— dry stop test (single brakecontrol actuated);
-
— wet brake test;
-
-
— parking brake system test;
-
— power-assisted brake system failure test.
NOTE The test methods (application, condition of the moped, test procedure and parameters, measurement of performances) for all the tests defined in this International Standard are equivalent to the corresponding test methods prescribed by UNECE Global Technical Regulation No. 3.
