in Annex 11, shall be rounded in one step to the number of places to the right of the decimal point indicated by the applicable emission standard plus one additional significant figure. Preceding steps in the calculations shall not be rounded.

              7.                                Performance requirements for instrumentation
              The instrumentation used for RDE tests shall comply with the requirements as defined in Annex 5. If requested by the authorities, the tester shall provide proof that the instrumentation used complies with the requirements in Annex 5.

              8.                                Test conditions
              Only an RDE test fulfilling the requirements of this Section shall be accepted as valid. Tests performed outside the test conditions specified in this Section shall be considered as invalid, unless specified otherwise.

              8.1. Ambient conditions

              The test shall be conducted under the ambient conditions laid down in this section. The ambient conditions become 'extended' when at least one of the temperature or altitude conditions is extended. The factor for extended conditions as defined in paragraph 10.5. shall only be applied once even if both conditions are extended in the same time period. Notwithstanding the opening paragraph of this section, if a part of the test or the entire test is performed outside of extended conditions, the test shall be invalid only when final emissions as calculated in Annex 11, are greater than the applicable emission limits. The conditions are as follows:

Moderate altitude conditions     Altitude lower or equal to 700 meters above sea level.

Extended altitude conditions     Altitude higher than 700 meters above sea level and lower or equal to 1300 meters above sea level.

Moderate temperature conditions  Greater than or equal to 273.15 K (0 °C) and lower than or equal to 308.15 K (35 °C).

Extended temperature conditions  Greater than or equal to 266.15 K (– 7 °C) and lower than 273.15 K (0 °C) or greater than 308.15 K (35 °C) and lower than or equal to 311.15 K (38 °C).

8.2. Dynamic conditions of trip
              The dynamic conditions encompass the effect of road grade, head wind and driving dynamics (accelerations, decelerations) and auxiliary systems upon energy consumption and emissions of the test vehicle. The validity of the trip for the dynamic conditions shall be checked after the test is completed, using the recorded data. This verification shall be conducted in 2 steps:

                  STEP i: The excess or insufficiency of driving dynamics during the trip shall be checked using the methods described in Annex 9.

                  STEP ii: If the trip is valid following the verifications in accordance with STEP i, the methods for verifying the validity of the trip as laid down in Annexes 8 and 10 shall be applied.

              8.3. Vehicle condition and operation

              8.3.1.  Vehicle condition

              The vehicle,
