ANNEXURE IV-Z THE CENTRAL MOTOR VEHICLES RULES, 1989 629

Notes:
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, described in EN ISO 4259 shall be used.
3. In case of national dispute concerning sulphur content, either EN ISO 20846 or EN
IS 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 percent
content of water and alcohol.
6. There shall be no intentional addition of compounds containing phosphorus, iron,
manganese, or lead to this reference fuel.
