              It is allowed to merge two or more interpolation families into the same KCO2 correction factor family if newly merged interpolation families meet at least one of the following criteria defined in (a) to (e) of this paragraph. The representative KCO2 shall be determined with preferably highest energy demand vehicle H within a family.

              At the request of the responsible authority, the manufacturer shall provide evidence on the justification and technical criteria for merging these interpolation families in the following cases:

              Two or more interpolation families are merged:

                  (a) Which were split because the maximum interpolation range of 20 g/km CO2 is exceeded (in case vehicle M measured: 30 g/km);

                  (b) Which were split due to different engine power ratings of the same physical combustion engine
                  (different power only related to software);

                  (c) Which were split because the n/v ratios are just outside the tolerance of 8 per cent;

                  (d) Which were split, but still fulfil all the family criteria of a single IP family;

                  (e) Which were split because there is a different number of powered axles.

              Different electric energy converters between recharge-plug-in and traction REESS shall not be considered as a criterion in the context of the correction factor family.

              6.6. Type 4 test (Determination of evaporative emissions)

              6.6.1. The Type 4 test shall be carried out on all vehicles with a petrol tank in accordance with the requirements of paragraphs 6.6.2. to 6.6.4. and Annex C3.

              For Level 1A;

              Mono-fuel gas vehicles are exempted.

              6.6.2. When tested in accordance with Annex C3 to this Regulation, evaporative emissions shall be less than that specified in Table 2.

6.6.3. Evaporative emission family
              6.6.3.1. Only vehicles that are identical with respect to the characteristics listed in (a), (d) and (e), technically equivalent with respect to the characteristics listed in (b) and (c) and similar or, where applicable, within the stated tolerance regarding the characteristics listed in (f) and (g) may be part of the same evaporative emission family:

              (a) Fuel tank system material and construction;

              (b) Vapour hose material;

              (c) Fuel line material and connection technique;

              (d) Sealed tank or non-sealed tank system;

              (e) Fuel tank relief valve setting (air ingestion and relief);

                  (f) Carbon canister butane working capacity (BWC300) within a 10 per cent range of the highest value (for carbon canisters with the same type of charcoal, the volume of charcoal shall be within 10 per cent of that for which the BWC300 was determined);

                  (g) Purge control system (for example, type of valve, purge control strategy).

              The manufacturer shall demonstrate the technical equivalence of points (b) and
