Notes :
1
The values quoted in the specifications are "true values". For establishing
the 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 2 R 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
fuel manufacturer shall nevertheless aim at a zero value where the
stipulated maximum value is 2R and at the mean value when quoting
maximum and minimum limits.
Should it be necessary to clarify whether a fuel meets the requirements of
the specifications the terms of ISO4259 shall be applied.
2
The fuel may contain oxidation inhibitors and metal deactivators normally
used to stabilise refinery petrol streams, but detergent/dispersive additives
and solvent oils shall not be added.
3
The actual sulphur content of the fuel used for the type I test shall be
reported.
4
Ethanol meeting the specification of EN15376 is the only oxygenate that
shall be intentionally added to the reference fuel.
5
There shall be no intentional addition of compounds containing
phosphorus, iron, manganese or lead to this reference fuel.
6
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.]
