  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 should 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 the questions as to whether a fuel meets the requirements of the specifications, the terms of ISO 4259 should be applied.

  2/ The range for cetane number is not in accordance with the requirements of a minimum range of 4R.  However, in the case of a dispute between fuel supplier and fuel user, the terms of ISO 4259 may be used to resolve such disputes provided replicate measurements, of sufficient number to achieve the necessary precision, are made in preference to single determinations.

  3/ The actual sulphur content of the fuel used for the Type I test shall be reported.

  4/ Even though oxidation stability is controlled, it is likely that shelf life will be limited.  Advice should be sought from the supplier as to storage conditions and life.
