(a)

For new vehicle types, from the entry into force of this Regulation;

(b)

For existing vehicle types, manufacturers shall, with regard to those vehicle types that cover vehicles placed on the market in 2020, provide the approval authority with evidence on the basis of which the approval authority shall confirm whether the test conditions referred to in points (a) to (d) of point 2.2a. have been met in the WLTP approval tests.

The confirmation shall indicate the interpolation family identifier, and the confirmation with regard to each of the test conditions referred to in points (a) to (d). The approval authority shall issue the confirmation to the manufacturer and shall ensure that the confirmation is recorded and can be made available without delay at the request of the Commission.

Textual Amendments

F3 Substituted by Commission Implementing Regulation (EU) 2018/1002 of 16 July 2018 amending Implementing Regulation (EU) 2017/1153 to clarify and simplify the correlation procedure and to adapt it to changes to Regulation (EU) 2017/1151 (Text with EEA relevance).

2.3.2. Determination of the pre-conditioning effect U.K.

In preparing the chassis-dynamometer for the execution of a type-approval test, the vehicle is pre-conditioned in order to reach similar conditions to those used in the coast-down test. The pre-conditioning procedure used in the WLTP test differs from that used for the purpose of NEDC so that, with equal road loads, the vehicle is considered subject to higher forces under the WLTP. That difference shall be set at 6 Newton and that value shall be used for the calculation of the NEDC road loads in accordance with point 2.3.8.

2.3.3. Ambient conditions referred to in point 3.1.1 of UN/ECE Regulation No 83 U.K.

For the purpose of the correlation tool, the test cell temperature shall be set at 25 °C.

Also in the case of a physical vehicle measurement pursuant to point 3, the test cell temperature shall be set at 25 °C. However, on request by the manufacturer, the test cell temperature may be set at a value between 20 to 25 °C for the physical measurement.

2.3.4. Determination of the initial battery state of charge U.K.

The initial battery state of charge shall be set to at least 99 per cent for the purpose of the correlation tool test. The same shall apply in the case of a physical vehicle test.

[F1 2.3.5. Determination of the difference in tyre pressure prescriptions U.K.

According to point 6.6.3 of Appendix 3 to Annex I to Regulation (EU) 2017/1151, the lowest recommended tyre pressure for the vehicle test mass shall be used during the coast down for the road load determination, while this is not specified in the NEDC. The tyre pressure to be taken into account for the purpose of calculating the NEDC road load in accordance with point 2.3.8 shall be the average between the two axles of the average between the minimum and maximum tyre pressure permitted for the selected tyres on each axle for the NEDC reference mass of the vehicle. The calculation shall be carried out for vehicle H and, where applicable, for vehicles L and R with the following formulae:

• For vehicle H:

• For vehicle L:

• For vehicle R:

Where,

P _max,

is the average of the maximum tyre pressures of the selected tyres for the two axles;

P _min,

is the average of the minimum tyre pressures of the selected tyres for the two axles.

The corresponding effect in terms of resistance applied to the vehicle shall be calculated using the following formulae for vehicles H, L and R:

• For vehicle H:

• For vehicle L:

• For vehicle R:

2.3.6. Determination of the tyre tread depth (TTD) U.K.

According to point 4.2.2.2 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151 the minimum tyre tread depth is 80 % for the WLTP test, while pursuant to point 4.2 of Appendix 7 to Annex 4a to UN/ECE Regulation No 83, the minimum allowed tyre tread depth for the purpose of the NEDC test is 50 % of the nominal value. That results in an average difference of 2 mm in tread depth between the two procedures. The corresponding effect in terms of the resistance applied to the vehicle shall be determined for the purpose of the NEDC road load calculation in point 2.3.8 in accordance with the following formulae for vehicles H, L and R:

• For vehicle H:

• For vehicle L:

• For vehicle R:

Where,

RM _n,H , RM _n,L, and RM _n,R are the reference masses of vehicles H, L and R determined in accordance with point 2.3.1.]

2.3.7. Determination of the inertia of rotating parts U.K.

For the purpose of the correlation tool:

During the simulation of the WLTP test four rotating wheels are to be considered, while for the purpose of the NEDC tests only two rotating wheels are to be considered. The effect this has on the forces applied to the vehicle shall be taken into account in accordance with the formulae set out in point 2.3.8.1.1(a)(3).

The acceleration and deceleration forces in the correlation tool shall be calculated for the NEDC simulation by considering the inertia of only two rotating wheels.

For the purpose of a physical test:

During the WLTP coastdown setting, coastdown times are to be transferred to forces and vice versa by taking into account the applicable test mass plus the effect of rotational mass (3 % of the sum of the MRO and 25 kg). For the NEDC coastdown setting, coastdown times are to be transferred to forces and vice versa by neglecting the effect of rotational mass (only NEDC vehicle inertia calculated in point 2.3.1 is used).

2.3.8. Determination of the NEDC road loads U.K.

[F3 2.3.8.1. In the case of WLTP road loads being determined in accordance with paragraphs 1-4 and 6 of Sub-Annex 4 to Annex XXI to Regulation (EU) 2017/1151 U.K.

Unless otherwise specified the formulae shall apply both in the case of simulations and in the case of physical vehicle tests.

The type approval authority or, where applicable, the technical service shall verify if the wind-tunnel facility referred to in paragraph 3.2.3.2.2.3. in Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151 is qualified to accurately determine the Δ(Cd × Af) values. If the wind-tunnel facility is not qualified, the highest aerodynamic drag value shall apply for all vehicles in the family.

The WLTP road load coefficients and test mass values referred to in the formulae set out in points 2.3.8.1.1. and 2.3.8.1.2. shall be those resulting from vehicle H and L as determined for the interpolation family in accordance with paragraph 5 of Sub-Annex 7 to Annex XXI to Regulation (EU) 2017/1151.

(b)

Notwithstanding point (a), where the cycle energy demand of the WLTP vehicle H and/or L does not result in the highest, or respectively, the lowest cycle energy demand for the NEDC vehicle H and/or L, the NEDC road load coefficients shall be determined in accordance with either of the following:

(i)

on the basis of the individual vehicle in the interpolation family with the highest, or respectively, the lowest NEDC cycle energy demand;

(ii)

on the basis of the combination of the highest, or respectively, the lowest of each of the road load relevant characteristics, i.e. aerodynamic drag, rolling resistance and mass, taken from any individual vehicle in the interpolation family.

The choice of the procedure set out in points (i) or (ii) shall be made by the manufacturer.
