5.2.9.  During operation of the vehicle the heating and defrosting devices shall be shut off.

        5.2.10.  The total driving distance or roller revolutions measured are recorded.

        5.2.11.  A four-wheel drive vehicle shall be tested in a two-wheel drive mode of operation. The determination of the total road force for dynamometer setting is performed while operating the vehicle in its primary designed driving mode.

        5.3.  Performing the test

        5.3.1. The provisions of paragraphs 6.2. to 6.6., excluding 6.2.2., of Annex 4 apply in respect of starting the engine, carrying out the test and taking the emission samples. The sampling begins before or at the initiation of the engine start-up procedure and ends on conclusion of the final idling period of the last elementary cycle of the Part One (urban driving cycle), after 780 seconds.

        The first driving cycle starts with a period of 11 seconds idling as soon as the engine has started.

        5.3.2.  For the analysis of the sampled emissions the provisions of paragraph 7.2. of Annex 4 apply. In performing the exhaust sample analysis the technical service shall exercise care to prevent condensation of water vapour in the exhaust gas sampling bags.

        5.3.3.  For the calculations of the mass emissions the provisions of paragraph 8 of Annex 4 apply.

        6.  OTHER REQUIREMENTS

        6.1. Irrational emission control strategy

        6.1.1.  Any irrational emission control strategy which results in a reduction in effectiveness of the emission control system under normal operating conditions at low temperature driving, so far as not covered by the standardised emission tests, may be considered a defeat device.

TYPE V TEST
           (Description of the endurance test for verifying the durabilityof pollution control devices)

        1. INTRODUCTION

        This Annex described the test for verifying the durability of anti-pollution devices equipping vehicles with positive-ignition or compression-ignition engines during an ageing test of 80,000 km.

        2.  TEST VEHICLE

        2.1.  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 5.1. below.

        3.  FUEL

        The durability test is conducted with a suitable commercially available fuel.

        4.  VEHICLE MAINTENANCE AND ADJUSTMENTS

        Maintenance, adjustments as well as the use of the test vehicle's controls shall be those recommended by the manufacturer.

        5.  VEHICLE OPERATION ON TRACK, ROAD OR ON CHASSIS DYNAMOMETER

        5.1.  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:

        5.1.1. the durability test schedule is composed of 11 cycles
