Commission Regulation (EU) 2017/2400 of 12 December 2017 implementing Regulation (EC) No 595/2009 of the European Parliament and of the Council as regards the determination of the CO2 emissions and fuel consumption of heavy-duty vehicles and amending Directive 2007/46/EC of the European Parliament and of the Council and Commission Regulation (EU) No 582/2011 (Text with EEA relevance) (c. 2400)

ANNEX VIII U.K. VERIFYING AIR DRAG DATA

2. Definitions U.K.

For the purposes of this Annex the following definitions shall apply:

(1)

‘Active aero device’ means measures which are activated by a control unit to reduce the air drag of the total vehicle.

(2)

‘Aero accessories’ mean optional devices which have the purpose to influence the air flow around the total vehicle.

(3)

‘A-pillar’ means the connection by a supporting structure between the cabin roof and the front bulkhead.

(4)

‘Body in white geometry’ means the supporting structure incl. the windshield of the cabin.

(5)

‘B-pillar’ means the connection by a supporting structure between the cabin floor and the cabin roof in the middle of the cabin.

(6)

‘Cab bottom’ means the supporting structure of the cabin floor.

(7)

‘Cabin over frame’ means distance from frame to cabin reference point in vertical Z. Distance is measured from top of horizontal frame to cabin reference point in vertical Z.

(8)

‘Cabin reference point’ means the reference point (X/Y/Z = 0/0/0) from the CAD coordinate system of the cabin or a clearly defined point of the cabin package e.g. heel point.

(9)

‘Cabin width’ means the horizontal distance of the left and right B-pillar of the cabin.

(10)

‘Constant speed test’ means measurement procedure to be carried out on a test track in order to determine the air drag.

(11)

‘Dataset’ means the data recorded during a single passing of a measurement section.

(12)

‘EMS’ means the European Modular System (EMS) in accordance with Council Directive 96/53/EC.

(13)

‘Frame height’ means distance of wheel center to top of horizontal frame in Z.

(14)

‘Heel point’ means the point which is representing the heel of shoe location on the depressed floor covering, when the bottom of shoe is in contact with the undepressed accelerator pedal and the ankle angle is at 87°. (ISO 20176:2011)

(15)

‘Measurement area(s)’ means designated part(s) of the test track consisting of at least one measurement section and a preceded stabilisation section.

(16)

‘Measurement section’ means a designated part of the test track which is relevant for data recording and data evaluation.

(17)

‘Roof height’ means distance in vertical Z from cabin reference point to highest point of roof w/o sunroof
