test family. The ambient conditions and payload requirements, as specified in paragraph 8.1. and paragraph 8.3.1. respectively, shall be used ex-ante to determine whether the conditions are acceptable for RDE testing.

              The approval authority shall propose a test trip in urban, rural and motorway/expressway operation meeting the requirements of paragraph 9.2. If applicable, for the purpose of trip design, the urban, rural and motorway/expressway parts shall be selected based on a topographic map.

              If for a vehicle the collection of ECU data influences the vehicle's emissions or performance, the entire PEMS test family to which the vehicle belongs shall be considered as non-compliant.

              For RDE tests performed during type approval, the type approval authority may verify if the test setup and the equipment used fulfil the requirements of Annexes 4 and 5 through a direct inspection or an analysis of the supporting evidence (e.g. photographs, records).

              9.5. Compliance of software tools

              Any software tool used to verify the trip validity and calculate emissions compliance with the provisions laid down in paragraphs 8 and 9 and Annexes 8, 9 10 and 11 shall be validated by an entity defined by the Contracting Party. Where such software tool is incorporated in the PEMS instrument, proof of the validation shall be provided along with the instrument.

              10.1. Emissions and trip evaluation

              The test shall be conducted in accordance with Annex 4.

              10.2. The trip validity shall be assessed in a three-step procedure as follows:

              STEP A: The trip complies with the general requirements, boundary conditions, trip and operational requirements, and the specifications for lubricating oil, fuel and reagents set out in paragraphs 8 and 9 and Annex 10.

              STEP B: The trip complies with the requirements set out in Annex 9.

              STEP C: The trip complies with the requirements set out in Annex 8.

              The steps of the procedure are detailed in Figure 6.

              If at least one of the requirements is not fulfilled, the trip shall be declared invalid.

              10.3. In order to preserve data integrity, it shall not be permitted to combine data of different RDE trips in a single data set or to modify or remove data from an RDE trip, except for cases mentioned explicitly in this Regulation.

              10.4. Emission results shall be calculated using the methods laid down in Annex 7 and Annex 11. The emissions calculations shall be made between test start and test end.

              10.5. The extended factor for this Regulation is set at 1.6. If during a particular time interval the ambient conditions
