Division 3.1.4.1
United Kingdom
In the case of category Tb tractors with a maximum design speed exceeding 60 km/h, the residual performance of the service braking system, in the event of failure in a part of its transmission, shall give a stopping distance not exceeding the following values and a mean fully developed deceleration not less than the following values, using a control force not exceeding 70 daN, when checked by the type-0 test with the engine disconnected from the following initial speeds for the relevant vehicle category:
| v [km/h] | Stopping distance LADEN — [m] | dm [m/s2] | Stopping distance UNLADEN — [m] | dm [m/s2] |
|---|---|---|---|---|
| 40 | 1,3 | 1,3 |
That requirement shall not be construed as a departure from the requirements concerning secondary braking.
