The calculated specific fuel consumption over the WHSC, SFCWHSC, determined in accordance with paragraph 5.3.3 shall be adjusted to a corrected value, SFCWHSC,corr, in order to account for the difference between the NCV of the fuel used during testing and the standard NCV for the respective engine fuel technology in accordance with the following equation:

SFC WHSC,corr = SFC WHSC NCV meas NCV std
