C-24.2, r. 47.1 - Regulation respecting low-speed vehicles

Full text
20. Tests are carried out in cold and hot conditions to check the efficiency of the service brakes of the vehicle. For each of the situations described in the third and fourth paragraphs, a series of 3 tests, at least one of which must meet the requirements provided for in those paragraphs, must be carried out.
The cold and hot testing of the service brake system are carried out according to the following method:
(1)  they take place on a flat surface;
(2)  the vehicle is driven at its top speed;
(3)  the force applied to the pedal does not exceed 500 N;
(4)  before the tests, the friction components in the brake system have been broken in following 100 brakings from the vehicle’s top speed to a deceleration that does not cause the friction components to overheat.
The following cold testing of the service brake system are carried out when the system is at ambient temperature:
(1)  a first series of tests is carried out without rendering any subsystem inoperative. In that situation, the braking distance must not be greater than 0.1 V + 0.006 V2;
(2)  a second series of tests is carried out with a subsystem rendered inoperative. In that situation, the braking distance must not be greater than 0.1 V + 0.0158 V2;
(3)  in the case of a vehicle equipped with a braking assistance system, a third series of tests is carried out with that system rendered inoperative. In that situation, the braking distance must not be greater than 0.1 V + 0.0158 V2;
(4)  in the case of a vehicle equipped with a regenerative braking system, a fourth series of tests is carried out with that system rendered inoperative. In that situation, the braking distance must not be greater than 0.1 V + 0.0158 V2.
Only one series of hot tests of the service brake system is carried out within the minute that follows the warming up of the system by means of successive decelerations from the vehicle’s top speed down to half that speed. That series of tests is carried out from the vehicle’s top speed to its complete stop. In that situation, the braking distance must not be greater than 1.4 x (0.1 V + 0.006 V2).
In addition, for all the tests prescribed by this section, the vehicle must not skid by more than 15° in relation to the longitudinal axis of the roadway when stopping and, if the wheels block, the rear wheels must not block before the front wheels.
