payload may be reproduced and an artificial load may be used.

              Approval authorities may request to test the vehicle with any payload between 10 to 100 per cent of the maximum vehicle payload. In case the mass of the PEMS equipment needed for operation exceeds 10 per cent of the maximum vehicle payload this mass may be considered as minimum payload.

              4.2. Ambient conditions
              The test shall be conducted under ambient conditions meeting the following conditions:
              Atmospheric pressure greater than or equal to 82.5 kPa,
              Temperature greater than or equal to 266 K (-7°C) and less than or equal to the temperature determined by the following equation at the specified atmospheric pressure:
              T = -0.4514 * (101.3 – pb) + 311
              Where:
              T is the ambient air temperature, K
              pb is the atmospheric pressure, kPa
              4.3. Engine coolant temperature
              The engine coolant temperature shall be in accordance with paragraph A.1.2.6.1. of Appendix 1 to this annex.
              4.4. The lubricating oil, fuel and reagent shall be within the specifications issued by the manufacturer.
              4.4.1. Lubricating oil

              The test lubricating oil shall be market oil and must comply with the specifications of the engine manufacturer.

              Oil samples shall be taken.

              4.4.2. Fuel

              The test fuel shall be market fuel covered by the relevant standards or reference fuel as specified in Annex 5 to this Regulation.

              4.4.2.1. If the manufacturer in accordance with paragraph 4. to this Regulation has declared the capability to meet the requirements of this Regulation on market fuels declared in paragraph 3.2.2.2.1. of Part 1 of Annex 1 to this Regulation, tests shall be conducted on at least one of the declared market fuels.
              4.4.2.2. Fuel samples shall be taken."
              4.4.3. Reagent
              For exhaust after-treatment systems that use a reagent to reduce emissions, the reagent shall be market reagent and must comply with the specifications of the engine manufacturer. A sample of the reagent shall be taken. The reagent shall not be frozen.
4.5. Trip requirements
The shares of operation shall be expressed as a percentage of the total trip duration.
The trip shall consist of urban driving followed by rural and motorway driving according to the shares specified in paragraphs 4.5.1. to 4.5.4. Where another testing order is justified for practical reasons and after the agreement of the Type Approval Authority another order may be used, however, the test shall always start with the urban driving.
For the purpose of this paragraph, "approximately" shall mean the target value ±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
