Common use of Test Cycle Clause in Contracts

Test Cycle. The operating cycle, made up of a Part One (urban cycle) and Part Two (extra-urban cycle), is illustrated in Figure 1. During the complete test the elementary urban cycle is run four times followed, by Part Two. 6.1.1. Elementary urban cycle Part One of the test cycle comprises 4 times the elementary urban cycle which is defined in Table 1, illustrated in Figure 2, and summarized below. Breakdown by phases: Time (s) per cent Idling 60 30.8 35.4 Deceleration, clutch disengaged 9 4.6 Gear-changing 8 4.1 Accelerations 36 18.5 Steady-speed periods 57 29.2 Decelerations 25 12.8 Total 195 100 Breakdown by use of gears Time (s) per cent Idling 60 30.8 35.4 Deceleration, clutch disengaged 9 4.6 Gear-changing 8 4.1 First gear 24 12.3 Second gear 53 27.2 Third gear 41 21 Total 195 100 General information: Average speed during test: 19 km/h Effective running time: 195 s Theoretical distance covered per cycle: 1.013 km Equivalent distance for the four cycles: 4.052 km 6.1.2. Extra-urban cycle 6.1.3. Use of the gearbox 6.1.3.1. If the maximum speed which can be attained in first gear is below 15 km/h, the second, third and fourth gears shall be used for the urban cycle (Part One) and the second, third, fourth and fifth gears for the extra-urban cycle (Part Two). The second, third and fourth gears may also be used for the urban cycle (Part One) and the second, third, fourth and fifth gears for the extra-urban cycle (Part Two) when the manufacturer's instructions recommend starting in second gear on level ground, or when first gear is therein defined as a gear reserved for cross-country driving, crawling or towing. Vehicles which do not attain the acceleration and maximum speed values required in the operating cycle shall be operated with the accelerator control fully depressed until they once again reach the required operating curve. Deviations from the operating cycle shall be recorded in the test report. Vehicles equipped with semi-automatic-shift gearboxes shall be tested by using the gears normally employed for driving, and the gear shift is used in accordance with the manufacturer's instructions. 6.1.3.2. Vehicles equipped with automatic-shift gearboxes shall be tested with the highest gear ("Drive") engaged. The accelerator shall be used in such a way as to obtain the steadiest acceleration possible, enabling the various gears to be engaged in the normal order. Furthermore, the gear-change points shown in Tables 1 and 2 of this annex shall not apply; acceleration shall continue throughout the period represented by the straight line connecting the end of each period of idling with the beginning of the next following period of steady speed. The tolerances given in paragraphs 6.1.3.4. and 6.1.3.5. below shall apply. 6.1.3.3. Vehicles equipped with an overdrive that the driver can actuate shall be tested with the overdrive out of action for the urban cycle (Part One) and with the overdrive in action for the extra-urban cycle (Part Two). 6.1.3.4. A tolerance of ± 2 km/h shall be allowed between the indicated speed and the theoretical speed during acceleration, during steady speed, and during deceleration when the vehicle's brakes are used. If the vehicle decelerates more rapidly without the use of the brakes, only the provisions of paragraph 6.4.4.3. below shall apply. Speed tolerances greater than those prescribed shall be accepted during phase changes provided that the tolerances are never exceeded for more than 0.5 s on any one occasion. 6.1.3.5. The time tolerances shall be ± 1.0 s. The above tolerances shall apply equally at the beginning and at the end of each gear-changing period for the urban cycle (Part One) and for the operations Nos. 3, 5 and 7 of the extra-urban cycle (Part Two). It should be noted that the time of two seconds allowed includes the time for changing gear and, if necessary, a certain amount of latitude to catch up with the cycle.
