Common use of Type-I test Clause in Contracts

Type-I test. (fade test) 1.5.1. With repeated braking 1.5.1.1. The service braking systems of all power-driven vehicles must be tested by successively applying and releasing the brakes a number of times, the vehicle being laden, in the conditions shown in the table below: Category of vehicles Conditions v1 [km/h] v2 [km/h] )t [sec] n M1 80 % vmax < 120 1/2 v1 45 15 M2 80 % vmax < 100 1/2 v1 55 15 N1 80 % vmax < 120 1/2 v1 55 15 ▇▇, ▇▇, ▇▇ 80 % vmax < 60 1/2 v1 60 20 where: v1 = initial speed, at beginning of braking v2 = speed at end of braking vmax = maximum speed of vehicle n = number of brake applications )t = duration of a braking cycle: time elapsing between the initiation of one brake application and the initiation of the next. 1.5.1.2. If the characteristics of the vehicle make it impossible to abide by the duration prescribed for )t, the duration may be increased; in any event, in addition to the time necessary for braking and accelerating the vehicle, a period of 10 seconds must be allowed in each cycle for stabilizing the speed v1. 1.5.1.3. In these tests, the force applied to the control must be so adjusted as to attain the mean fully developed deceleration of 3 m/s2 at the first brake application; this force must remain constant throughout the succeeding brake applications. 1.5.1.4. During brake applications, the highest gear ratio (excluding overdrive, etc.) must be continuously engaged. E/ECE/324 Rev.1/Add.12/Rev.4 Regulation No. 13 page 59 Annex 4 1.5.1.5. For regaining speed after braking, the gearbox must be used in such a way as to attain the speed v1 in the shortest possible time (maximum acceleration allowed by the engine and gearbox). 1.5.1.6. For electric vehicles not having sufficient autonomy to carry out the cycles of heating of the brakes, the tests shall be carried out from the specified speed during the first braking application and after that by using the maximum acceleration capability of the vehicle, and braking successively from the speed reached at the end of each cycle with a duration specified for the relevant category of vehicle. 1.5.2. With continuous braking 1.5.2.1. The service brakes of trailers of categories O2 and O3 must be tested in such a manner that, the vehicle being laden, the energy input to the brakes is equivalent to that recorded in the same period of time with a laden vehicle driven at a steady speed of 40 km/h on a 7 per cent down-gradient for a distance of 1.7 km. 1.5.2.2. The test may be carried out on a level road, the trailer being drawn by a towing vehicle; during the test, the force applied to the control must be adjusted so as to keep the resistance of the trailer constant (7 per cent of the maximum total stationary axle load of the trailer). If the power available for hauling is insufficient, the test can be conducted at a lower speed but over a greater distance as shown in the table below:
