    1. An engine exhaust system or a test laboratory system shall be used presenting an exhaust backpressure within ± 650 Pa of the maximum value specified by the manufacturer at the rated speed and full load.
    2. ‘The test engine shall be equipped with an exhaust system with exhaust back pressure within ± 650 Pa of the value specified by the manufacturer at the engine operating conditions resulting in maximum declared power.
    3. An engine air intake system must be used presenting an air intake restriction within ± 100 Pa of the upper limit of the engine operating at the speed at the declared maximum power and full load.
    4. An engine air intake system shall be used presenting an air intake restriction within ± 100 Pa of the upper limit of the engine operating at the speed at the declared maximum power and full load.
    5. An engine air intake system shall be used presenting an air intake restriction within ± 100 Pa of the upper limit of the engine operating at the speed at the declared maximum power and full load.
    6. The complete exhaust system shall be fitted as provided for the intended application:Where there is a risk of an appreciable effect on the engine powerIn the case of two-stroke and positive ignition enginesWhen the manufacturer requests that this should be done.In other cases, an equivalent system may be installed provided the pressure measured at the exit of the engine exhaust system does not differ by more than 1000 Pa from that specified by the manufacturer.
    7. An exhaust system shall be used presenting an exhaust back pressure within ± 1000 Pa of the upper limit of the engine operating at the speed of declared maximum power and full load and a volume within ± 40 % of that specified by the manufacturer.
    8. The complete intake system shall be fitted as provided for the intended application:Where there is a risk of an appreciable effect on the engine powerIn the case of two-stroke and positive-ignition enginesWhen the manufacturer requests that this should be done.In other cases, an equivalent system may be used and a check should be made to ascertain that the intake pressure does not differ by more than 100 Pa from the limit specified by the manufacturer for a clean air filter.
    9. The complete intake system shall be fitted as provided for the intended application:where there is a risk of an appreciable effect on the engine power;in the case of two-stroke and positive-ignition engines;when the manufacturer requests that this should be done.In other cases, an equivalent system may be used and a check should be made to ascertain that the intake pressure does not differ by more than 100 Pa from the limit specified by the manufacturer for a clean air filter.
