Division 6.7.1 Correction of the flat belt and chassis dynamometer results

The measured forces determined in paragraphs 6.5. and 6.6. of this Sub-Annex shall be corrected to reference conditions using the following equation:

F_{Dj} = (f_{j} - K_{1}) \times (1 + K_{0} (T - 293))

where:

F_Dj

is the corrected resistance measured at the flat belt or chassis dynamometer at reference speed j, N;

f_j

is the measured force at reference speed j, N;

K₀

is the correction factor for rolling resistance as defined in paragraph 4.5.2. of this Sub-Annex, K^-1;

K₁

is the test mass correction as defined in paragraph 4.5.4. of this Sub-Annex, N;

is the arithmetic average temperature in the test cell during the measurement, K.
