1. 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.
2. In case of dispute, the procedure for dissolving the dispute and
interpretations of the results based on test method precision, describe in EN
ISO 4259 shall be used.
3. In case 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.
4. The actual sulphur content of the fuel used for the Type I Test shall be
reported.
5. The unleaded petrol content can be determined as 100- minus the sum of
the per cent content of water and alcohol.
6. There shall be no intentional addition of compounds containing
phosphorus, iron, manganese, or lead to this reference fuel.
7. Ethanol to meet the specification of EN 15376 is the only oxygenate that shall
be intentionally added to this reference fuel.
