    Abstract - (Show below) - (Hide below)

    This European Standard describes a procedure for the determination of acid strength, as a pHe value, of ethanol to be used as a blend component for gasoline.NOTEFor the purposes of this European Standard, the term “% (V/V)” is used to represent the volume fraction.
