speeds  greater than or equal to 45 km/h and lower than 80 km/h.

              4.4.1.3. High speed windows

              High speed windows are characterized by average vehicle ground speeds  greater than or equal to 80 km/h and lower than 145 km/h

              4.4.2. Low/and high speed windows (for analysis with 3-phase WLTP)

              The windows shall be categorised into low and high speed bins according to their average speed.

              4.4.2.1. Low speed windows

              Low speed windows are characterized by average vehicle ground speeds lower than 50 km/h.

              4.4.2.2. High speed windows

              High speed windows are characterized by average vehicle ground speeds  greater than or equal to 50 km/h.

              4.5.1. Assessment of trip validity (for analysis with 4-phase WLTP)

              4.5.1.1. Tolerances around the vehicle CO2 characteristic curve

              The upper tolerance of the vehicle CO2 characteristic curve is  for low speed driving and  for medium and high speed driving.

              The lower tolerance of the vehicle CO2 characteristic curve is  for ICE and NOVC-HEV vehicles and  for OVC-HEV vehicles.

              4.5.1.2. Assessment of test validity

              The test is valid when it comprises at least 50 per cent of the low, medium and high speed windows that are within the tolerances defined for the CO2 characteristic curve.

              For NOVC-HEVs and OVC-HEVs, if the minimum requirement of 50 per cent between  and  is not met, the upper positive tolerance  may be increased until the value of  reaches 50 per cent.

              For OVC-HEVs when no MAWs are calculated as result of the ICE not turning on, the test is still valid.

              4.5.2.1. Tolerances around the vehicle CO2 characteristic curve

              The upper tolerance of the vehicle CO2 characteristic curve is  for low speed driving and  for high speed driving.

              The lower tolerance of the vehicle CO2 characteristic curve is  for ICE and NOVC-HEV vehicles and  for OVC-HEV vehicles.

              4.5.2.2. Assessment of test validity

              The test is valid when it comprises at least 50 per cent of the low, and high speed windows that are within the tolerances defined for the CO2 characteristic curve.

              For NOVC-HEVs and OVC-HEVs, if the minimum requirement of 50 per cent between  and  is not met, the upper positive tolerance  may be increased by steps of 1 per cent until the 50% target is reached. When using this mechanism, the value of
