It is applicable to unleaded petrol for use in petrol engine vehicles designed to run on unleaded petrol. This document 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; - one type in Table 2 with a maximum oxygen content of 2,7 % (m/m) and a maximum ethanol content of 5,0 % (V/V) intended for older vehicles that are not warranted to use unleaded petrol defined in Table 1. NOTE 1 The two types are based on European Directive requirements [3], [4] and [13]. NOTE 2 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction, µ, and the volume fraction, φ.
