Division 7 CALCULATION OF THE STATISTICAL ERROR

The statistical errors in the results of the testing methodology caused by the measurements shall be quantified. For each operating point the standard deviation shall be calculated in accordance with Formula 7:

The standard deviation of the efficiency value of the efficient alternator (s_ηEI) shall be calculated in accordance with Formula 8:

The standard deviation of the alternator efficiency (s_ηEI) leads to an error in the CO₂ savings (). That error shall be calculated in accordance with Formula 9:
