              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 Regulation.
              5.3.7.2. When tested in accordance with Annex 5 to this Regulation (Type 2 test) at normal idling speed:
                  (a) The carbon monoxide content by volume of the exhaust  gases emitted shall be recorded; and
                  (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; and
                  (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 Non-Dispersive Infrared (NDIR) measurement to Flame Ionisation Detector (FID) measurement (provided by manufacturer of measuring equipment),
              Hcv = Atomic ratio of hydrogen to carbon:
                  (a) for petrol (E10) 1.93;
                  (b) for LPG 2.53;
                  (c) for NG/biomethane 4.0;
                  (d) for ethanol (E85) 2.74;
                  (e) for ethanol (E75) 2.61.
              Ocv = Atomic ratio of oxygen to carbon:
                  (a) for petrol (E10) 0.033;
                  (b) for LPG 0.0;
                  (c) for NG/biomethane 0.0;
                  (d) for ethanol (E85) 0.39;
              (e) for ethanol (E75) 0.329.

              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 of item 2.2. of the Addendum to Annex 2 to this Regulation 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 type approval authority. An assessment shall be made based on surveys and studies of production vehicles.

              7. Extensions to type approvals
7.1.  Extensions for tailpipe emissions (Type 2 test)
              7.1.1. The type approval shall be extended without the need for further testing to vehicles if they conform to the criteria of paragraph 3.0.1. (c) of UN Regulation No. 154.
              7.2. Extensions for low temperature test (Type 6 test)
              7.2.1. Vehicles with different reference masses
              7.2.1.1. The type approval shall be extended only to vehicles with a reference mass requiring the
