              2.4.1. The provisions of Appendix 3 to Annex 4a to the 07 series of amendments to this Regulation apply, but only for carbon monoxide, carbon dioxide, and total hydrocarbon testing.
              2.4.2. For calibrations of the analytical equipment the provisions of Annex 4a to the 07 series of amendments to this Regulation apply.
              2.5. Gases
              2.5.1. The provisions of paragraph 3. of Appendix 3 to Annex 4a to the 07 series of amendments to this Regulation apply, where they are relevant.
              2.6. Additional equipment
              2.6.1. For equipment used for the measurement of volume, temperature, pressure and humidity the provisions in paragraph 4.6. of Annex 4a to the 07 series of amendments to this Regulation apply.
              3. Test sequence and fuel
              3.1. General requirements
              3.1.1. The test sequence in Figure A8/1 shows the steps encountered as the test vehicle undergoes the procedures for the Type 6 test. Ambient temperature levels encountered by the test vehicle shall average: 266 K (-7 °C) 3 K and shall not be less than 260 K (-13 °C), or more than 272 K (-1 °C).
               The temperature may not fall below 263 K (-10 °C), or exceed 269 K (-4 °C) for more than three consecutive minutes.
              3.1.2. The test cell temperature monitored during testing shall be measured at the output of the cooling fan (paragraph 5.2.1. of this annex). The ambient temperature reported shall be an arithmetic average of the test cell temperatures measured at constant intervals no more than one minute apart.
              3.2. Test procedure
               The Part One, urban driving cycle, according to Figure A4a/1 in Annex 4a to the 07 series of amendments to this Regulation, consists of four elementary urban cycles which together make a complete Part One cycle.
              3.2.1. Start of engine, start of the sampling and the operation of the first cycle shall be in accordance with Table A4a/1 and Figure A4a/1 in Annex 4a to the 07 series of amendments to this Regulation.
              3.3. Preparation for the test
              3.3.1. For the test vehicle the provisions of paragraph 3.2. of Annex 4a to the 07 series of amendments to this Regulation apply. For setting the equivalent inertia mass on the dynamometer the provisions of paragraph 6.2.1. of Annex 4a to the 07 series of amendments to this Regulation apply.

              3.4. Test fuel
              3.4.1. The test fuel shall comply with the specifications given in paragraph 2. of Annex 10 to this Regulation.
              3.5. The road load coefficients to be used shall be those for vehicle low (VL). If VL does not exist then the vehicle high (VH) road load
