This Technical Report explains the requirements and test methods for marketed and delivered ethanol (E85) automotive fuel according to EN 15293. It provides background information on the final text of the draft European standard and gives guidance and explanations to the producers, blenders, marketers and users of ethanol (E85) automotive fuel. It is applicable to ethanol (E85) for use in spark ignition engine vehicles designed to run on ethanol (E85). Ethanol (E85) is a mixture of nominally 85 % ethanol and 15 % petrol, but it also includes the possibility of having different 'seasonal grades' containing 50 % or more ethanol. NOTE 1 This document is directly related to prEN 15293:2017 and will be updated if further revisions to the standard take place. NOTE 2 For the purposes of this document, the terms “% (m/m)” and “% (V/V)” are used to represent the mass fraction, µ, and the volume fraction, f, respectively.
