Footnotes

f1: 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.
f2: A correction factor of 0,2 for MON and RON shall be subtracted for the calculation of the final result in accordance with EN 228:2008.
f3: A correction factor of 0,2 for MON and RON shall be subtracted for the calculation of the final result in accordance with EN 228:2008.
f4: The fuel may contain oxidation inhibitors and metal deactivators normally used to stabilise refinery gasoline streams, but detergent/dispersive additives and solvent oils shall not be added.
f5: Ethanol is the only oxygenate that shall be intentionally added to the reference fuel. The Ethanol used shall conform to EN 15376.
f6: The actual sulphur content of the fuel used for the Type 1 test shall be reported.
f7: There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
f8: Ethanol is the only oxygenate that shall be intentionally added to the reference fuel. The Ethanol used shall conform to EN 15376.
f9: 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.
f10: In cases of dispute, the procedures for resolving the dispute and interpretation of the results based on test method precision, described in EN ISO 4259 shall be used.
f11: In cases of national dispute concerning sulphur content, either EN ISO 20846 or EN ISO 20884 shall be called up similar to the reference in the national annex of EN 228.
f12: The actual sulphur content of the fuel used for the Type 1 test shall be reported.
f13: Ethanol to meet specification of EN 15376 is the only oxygenate that shall be intentionally added to this reference fuel.
f14: The unleaded petrol content can be determined as 100 minus the sum of the percentage content of water and alcohols
f15: There shall be no intentional addition of compounds containing phosphorus, iron, manganese, or lead to this reference fuel.
f16: This method may not accurately determine the presence of corrosive materials if the sample contains corrosion inhibitors or other chemicals which diminish the corrosivity of the sample to the copper strip. Therefore, the addition of such compounds for the sole purpose of biasing the test method is prohibited.
f17: Inerts (different from N₂) + C₂ + C₂₊.
f18: Value to be determined at 293,2 K (20 C) and 101,3 kPa.
f19: Value to be determined at 273,2 K (0 C) and 101,3 kPa.
f20: Inerts (different from N₂) + C₂; + C₂₊.
f21: Value to be determined at 293,2 K (20 C) and 101,3 kPa.
f22: Value to be determined at 273,2 K (0 C) and 101,3 kPa.
f23: Not to be condensed.
f24: Combined water, oxygen, nitrogen and argon: 1,900 μmol/mol.
f25: Combined water, oxygen, nitrogen and argon: 1,900 μmol/mol.
f26: Combined water, oxygen, nitrogen and argon: 1,900 μmol/mol.
f27: Combined water, oxygen, nitrogen and argon: 1,900 μmol/mol.
f28: The hydrogen shall not contain dust, sand, dirt, gums, oils, or other substances in an amount sufficient to damage the fuelling station equipment or the vehicle (engine) being fuelled.
