                                       The values quoted in the specifications are "true values". For establishing the limit
                                 values, the terms of ISO 4259:2006 (Petroleum products—Determination and applica-
                                 tion of precision data in relation to methods of test) have been applied and for fixing a
                                 minimum value, a minimum difference of 2R above zero has been taken into account;
                                 for  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 ISO 4259:2006 shall be applied.
                                      2
                                       The fuel may contain oxidation inhibitors and metal deactivators normally used
                                 to stabilize 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 prEN 15376 is the only oxygenate that shall
                                 be intentionally added to the reference fuel.
