# Commission Delegated Regulation (EU) 2017/654 of 19 December 2016 supplementing Regulation (EU) 2016/1628 of the European Parliament and of the Council with regard to technical and general requirements relating to emission limits and type-approval for internal combustion engines for non-road mobile machinery, Division 2.2: Type: Ethanol (E85)

Extent: E+W+S+N.I.

Notes:
The values quoted in the specifications are ‘true values’. In establishment of their limit values the terms of ISO 4259 Petroleum products — Determination and application of precision data in relation to methods of test have been applied and in fixing a minimum value, a minimum difference of 2R above zero has been taken into account; in fixing a maximum and minimum value, the minimum difference is 4R (R = reproducibility). Notwithstanding this measure, which is necessary for technical reasons, the manufacturer of fuels shall nevertheless aim at a zero value where the stipulated maximum value is 2R and at the mean value in the case of quotations of maximum and minimum limits. Should it be necessary to clarify whether a fuel meets the requirements of the specifications, the terms of ISO 4259 shall be applied.
The actual sulphur content of the fuel used for the emission tests shall be reported.
Ethanol to meet specification of EN 15376 is the only oxygenate that shall be intentionally added to this reference fuel.
The unleaded petrol content can be determined as 100 minus the sum of the % content of water, alcohols, MTBE and ETBE.
There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
