Common use of Secondary braking system Clause in Contracts

Secondary braking system. 2.2.1. The secondary braking system, even if the control which actuates it is also used for other braking functions, must give a stopping distance not exceeding the following values and a mean fully developed deceleration not less than the following values: Category M1 0.1 v + (2v2/150) (the second term corresponds to a mean fully developed deceleration dm = 2.9 m/s2) Category M2, M3 0.15 v + (2v2/130) (the second term corresponds to a mean fully developed deceleration dm = 2.5 m/s2) Category N 0.15 v + (2v2/115) (the second term corresponds to a mean fully developed deceleration dm = 2.2 m/s2) 2.2.2. If the control is manual, the prescribed performance must be obtained by applying to the control a force not exceeding 40 ▇▇▇ in the case of vehicles of category M1, and 60 ▇▇▇ in the case of other vehicles, and the control must be so placed that it can be easily and quickly grasped by the driver. 2.2.3. If it is a foot control, the prescribed performance must be obtained by applying to the control a force not exceeding 50 ▇▇▇ in the case of vehicles of category M1, and 70 ▇▇▇ in the case of other vehicles, and the control must be so placed that it can be easily and quickly actuated by the driver. E/ECE/324 Rev.1/Add.12/Rev.4 Regulation No. 13 page 71 Annex 4 2.2.4. The performance of the secondary braking system must be checked by the Type-0 test with engine disconnected from the following initial speeds: M1: 80 km/h M 2: 60 km/h M3: 60 km/h N1: 70 km/h N2: 50 km/h N3: 40 km/h 2.2.5. The secondary braking effectiveness test shall be conducted by simulating the actual failure conditions in the service braking system. 2.2.6. For electric vehicles, the performances for the two following additional failures shall be checked: 2.2.6.1. For a total failure of the electric component of the service braking; 2.2.6.2. In the case where the electric component delivers the maximum braking force when a failure of the electric transmission occurs.
