and deliver appropriate exhaust flow, exhaust constituents, and exhaust temperature to the after-treatment system inlet.
                The manufacturer shall record the number of regenerations/desulphurisations (if applicable) to assure that sufficient ageing has actually occurred.
              2.3.2.6. Required Testing. For calculating deterioration factors at least two Type I Tests before bench ageing of the emission control hardware and at least two Type I Tests after the bench-aged emission hardware is reinstalled have to be performed. Additional testing may be conducted by the manufacturer. Calculation of the deterioration factors shall be done according to the calculation method set out in paragraph 7. of this Annex and with the additional requirements contained in this Regulation.
              3. Test vehicle
              3.1. The vehicle shall be in good mechanical order; the engine and the anti-pollution devices shall be new. The vehicle may be the same as that presented for the Type I Test; this Type I Test has to be done after the vehicle has run at least 3,000 km of the ageing cycle of paragraph 6.1. below.
              4. Fuel
               The durability test is conducted with a suitable commercially available fuel.
              5. Vehicle maintenance and adjustments
               Maintenance, adjustments as well as the use of the test vehicle's controls shall be those recommended by the manufacturer.
              6. Vehicle operation on track, road or on chassis dynamometer
              6.1. Operating cycle
               During operation on track, road or on roller test bench, the distance shall be covered according to the driving schedule (Figure 9/1) described below:
              6.1.1. The durability test schedule is composed of 11 cycles covering 6 kilometres each,
              6.1.2. During the first nine cycles, the vehicle is stopped four times in the middle of the cycle, with the engine idling each time for 15 seconds,
              6.1.3. Normal acceleration and deceleration,
              6.1.4. Five decelerations in the middle of each cycle, dropping from cycle speed to 32 km/h, and the vehicle is gradually accelerated again until cycle speed is attained,
              6.1.5. The 10th cycle is carried out at a steady speed of 89 km/h,
              6.1.6. The 11th cycle begins with maximum acceleration from stop point up to 113 km/h. At half-way, braking is employed normally until the vehicle comes to a stop. This is followed by an idle period of 15 seconds and a second maximum acceleration.
               The schedule is then restarted from the beginning.
               The maximum speed of each cycle is given in the following table.
