1 Scope
This European Standard specifies requirements and test methods for marketed and delivered
unleaded petrol. It is applicable to unleaded petrol for use in petrol engine vehicles
designed to run on unleaded petrol.
This European Standard specifies two types of unleaded petrol: one type with a maximum
oxygen content of 3,7 % ( m/m ) and a maximum ethanol content of 10,0 % ( V/V ) in Table 1, and one type intended for older vehicles that are not warranted to use unleaded
petrol with a high biofuel content, with a maximum oxygen content of 2,7 % ( m/m ) and a maximum ethanol content of 5,0 % ( V/V ) in Table 2.
NOTE 1 The two types are based on European Directive requirements [3], [4],[11]".
NOTE 2 For the purposes of this European Standard, the terms “% ( m/m )” and “% ( V/V )” are used to represent respectively the mass fraction, µ , and the volume fraction, φ .
