±5 per cent.
Urban, rural and motorway parts can be determined either on the basis of:
(a) Geographical coordinates (by means of a map); or
(b) First acceleration method.
In case the trip composition is determined on the basis of geographical coordinates, the vehicle should not exceed, for a cumulative period longer than 5 per cent of the total duration of each part of the trip, the following speed:
(a) 50 km/h in the urban part;
(b) 75 km/h in the rural part (90 km/h in the case of vehicles of categories M1 and N1).
In case the trip composition is determined by means of the first acceleration method, the first acceleration above 55 km/h (70 km/h in the case of vehicles of categories M1 and N1) shall indicate the beginning of the rural part and the first acceleration above 75 km/h (90 km/h in the case of vehicles of categories M1 and N1) shall indicate the beginning of the motorway part.
The criteria for differentiation between urban, rural and motorway operation shall be agreed with the approval authority prior to the beginning of the test.
Average speed in urban operation shall be between 15 and 30 km/h.
Average speed in rural operation shall be between 45 and 70 km/h (60 and 90 km/h in the case of vehicles of categories M1 and N1).
              Average speed in motorway operation shall be above 70 km/h (90 km/h in the case of vehicles of categories M1 and N1).
              4.5.1. For M1 and N1 vehicles the trip shall consist of approximately 34 per cent urban, 33 per cent rural and 33 per cent motorway operation.
              4.5.2. For N2, M2 and M3 vehicles the trip shall consist of approximately 45 per cent urban, 25 per cent rural and 30 per cent motorway operation. M2 and M3 vehicles of Class I, II or Class A shall be tested in approximately 70 per cent urban and 30 per cent rural operation.
              4.5.3. For N3 vehicles the trip shall consist of approximately 30 per cent urban, 25 per cent rural and followed by 45 per cent motorway operation.
4.5.4. For the purpose of the assessment of the trip composition, the duration of the share shall be calculated from the moment when the coolant temperature has reached 343 K (70 °C) for the first time or after the coolant temperature is stabilised within ±2 K over a period of 5 minutes whichever comes first but no later than 15 minutes after engine start. In accordance with paragraph 4.5. the period elapsed to reach the coolant temperature of 343 K (70 °C) shall be operated under urban driving conditions.
