(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)

(15)

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