               At the request of the manufacturer, the Technical Service may carry out the Type I test before the Type V test has been completed using the deterioration factors in the table above. On completion of the Type V test, the Technical Service may then amend the type approval results recorded in Annex 2 by replacing the deterioration factors in the above table with those measured in the Type V Test.
              5.3.6.3. Deterioration factors are determined using either procedure in paragraph 5.3.6.1. or using the values in the table in paragraph 5.3.6.2. The factors are used to establish compliance with the requirements of paragraphs 5.3.1.4. and 8.2.3.1.
              5.3.7. Emission data required for roadworthiness testing
              5.3.7.1. This requirement applies to all vehicles powered by a positive-ignition engine for which type approval is sought in accordance with this amendment.
              5.3.7.2. When tested in accordance with Annex 5 (Type II test) at normal idling speed:
                  (a) The carbon monoxide content by volume of the exhaust  gases emitted shall be recorded;
                  (b) The engine speed during the test shall be recorded, including any tolerances.
5.3.7.3. When tested at "high idle" speed (i. e. > 2,000 min.-1)
                  (a) The carbon monoxide content by volume of the exhaust gases emitted shall be recorded;
                  (b) The Lambda value (*) shall be recorded;
                  (c) The engine speed during the test shall be recorded, including any tolerances.
(*) The Lambda value shall be calculated using the simplified Brettschneider equation  as follows:

  Where:
[ ]  =  concentration in per cent volume,
K1   =  conversion factor for NDIR measurement to FID measurement (provided by manufacturer of measuring equipment),
Hcv  =  Atomic ratio of hydrogen to carbon,
         (a) for petrol (E5) 1.89
         (b) for LPG 2.53
                     (c) for NG/biomethane 4.0
        (d) for ethanol (E85) 2.74
Ocv  =  Atomic ratio of oxygen to carbon,
         (a) for petrol (E5) 0.016
         (b) for LPG 0.0
         (c) for NG/biomethane 0.0
        (d) for ethanol (E85) 0.39

              5.3.7.4. The engine oil temperature at the time of the test shall be measured and recorded.
5.3.7.5. The table in item 2.2 to Annex 2 shall be completed.
              5.3.7.6. The manufacturer shall confirm the accuracy of the Lambda value recorded at the time of type approval in paragraph 5.3.7.3. as being representative of typical production vehicles within 24 months of the date of the granting of type approval by the Competent Authority. An assessment shall be made based on surveys and studies of production vehicles.
              5.3.8. On-board diagnostics OBD - test
               This test shall be carried out on all vehicles referred to in
