The statistical errors in the results of the testing methodology caused by the measurements are to be quantified. For each operating point the standard deviation is calculated as defined by the following formula:
sηEIi–=sηEIim=∑mj=1ηEIij−ηEIi–2mm−1
The standard deviation of the efficiency value of the efficient alternator (sηEI) is calculated in accordance with formula 8:
sηEI=∑i=14hi×sηEIi–2
The standard deviation of the alternator efficiency (sηEI) leads to an error in the CO2 savings (sCCO2). That error is calculated in accordance with formula 9:

It has to be demonstrated for each type, variant and version of a vehicle fitted with the efficient alternator that the error in the CO2 savings calculated in accordance with Formula 9 is not greater than the difference between the total CO2 savings and the minimum savings threshold specified in Article 9(1) of Implementing Regulation (EU) No 725/2011 (see Formula 10).
MT≤CCO2−sCCO2
where:

MTMinimum threshold [g CO2/km], which is 1 g CO2/km

The report shall include:


— Model and mass of the tested alternators
— Description of the bench
— Test results (measured values)
— Calculated results and corresponding formulae

The  Secretary of State  is to certify the CO2 savings based on measurements of the efficient alternator and the baseline alternator using the test methodology set out in this Annex. Where the CO2 emission savings are below the threshold specified in Article 9(1), the second subparagraph of Article 11(2) of Implementing Regulation (EU) No 725/2011 shall apply.
