This document specifies requirements and test methods for marketed and delivered automotive ethanol (E85) fuel. It is applicable to automotive ethanol (E85) fuel for use in spark ignition engine vehicles designed to run on automotive ethanol (E85) fuel.
Automotive ethanol (E85) fuel is a mixture of nominally 85 % (V/V) ethanol and unleaded petrol, but also including the possibility of having different “seasonal grades” containing more than 50 % (V/V) ethanol.
NOTE 1 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent respectively the mass fraction and the volume fraction.
NOTE 2 For this European Standard, A-deviations apply (see Annex C).
