Notes
NOTES
1.) The fuel covered by this standard is intended for use in petrol-engined road vehicles which require high octane unleaded petrol.
2.) Parameters that do not form part of the BS EN 228 are routinely tested as per confidential agreements with individual customers.
NOTE: Requirements in bold refer to the European Fuels Directive 98/70/EC [1], including subsequent Amendments [2], [3] and [4]
a) See also 5.7.1.
b) A correction of 0,2 for MON and RON shall be subtracted for the calculation of the final result, before reporting according to the requirement of the European Fuels Directive 98/70/EC [1], including subsequent Amendments [2], [3] and [4]. See also 5.6 and 5.7.2.
c) See also 5.7.2.
d) See also 5.3.3.
e) Appearance shall be determined at ambient temperature.
f) Stabilising agents shall be added.
g) Ethanol when used as a blending component shall conform to EN 15376 (see 5.1). Stabilising agents may be added.
h) The oxygen content of the finished unleaded petrol shall not exceed 2,7 % (m/m). A CEN/TR on oxygenate blending is under preparation.
i) Other mono-alcohols and ethers with a final boiling point no higher than prescribed in Table 4. BS EN 228:2012
