Division 6.2.2

Two separate coastdown tests shall be performed with each of the three vehicles according to paragraph 4.3. of this Sub-Annex, and the resulting road load coefficients, f₀, f₁ and f₂, shall be determined according to that paragraph and corrected according to paragraph 4.5.5. of this Sub-Annex. The coastdown test result of a test vehicle shall be the arithmetic average of the road load coefficients of its two separate coastdown tests. If more than two coastdown tests are necessary to fulfil the approval of facilities' criteria, all valid tests shall be averaged.
