All vehicles sampled in Article 1.1.1 shall be subject to this test. The test shall be conducted in accordance with the provisions of Article 5.3.2.
7.1.3 When conducting type tests, the test shall be conducted in accordance with the provisions of F7 in Appendix E. 8 Low-power vehicles
For N-type and M-type (referring only to M-type vehicles with a design passenger number (including the driver) exceeding 6 persons, or a maximum total vehicle mass exceeding 2500kg but not exceeding 3500kg) vehicles with a power to load mass ratio of less than 30kW/1000kg and a maximum vehicle speed not exceeding 130km/h, before January 1, 2006: the maximum vehicle speed limit for the suburban operating cycle (2 units) is: 90km/h. 9 Implementation date of standard limits

r/min2 If the manufacturer requires running-in of these vehicles ("\1" represents the vehicle running-in mileage), the following steps shall be followed: 1) For the first vehicle, measure the pollutant emissions of its type test before running-in (0 km) and after running-in ("r" km/km); 2) Calculate the emission efficiency gradient coefficient (Ec) of each pollutant between (km and r\km): "emission at \km
emission at km
The emission gradient coefficient may be less than 1:
3) Other vehicles do not need to be run-in, but their measured 0 k emissions will be multiplied by the corresponding gradient coefficient mentioned above. At this time, the values used for production consistency judgment are: a) the measured value of the first vehicle at \a:\km; h) the value of the measured value of other vehicles at 0 km multiplied by the emission gradient coefficient. 7.1.1.2.3 The above test can use commercially available fuels.
