Proposal to clarify the wording of the determination of the net power for electric motors and to correct an error in the formula presented in paragraph 5.4.2. Diesel engines – Factor αd. The parameter “fm” in the equation should be a superscript (e.g., meaning “to the power of fm”). Through a transcription error, this factor was rendered in normal text.
