This European Standard specifies a determination method of methanol in automotive ethanol (E85) fuel by capillary gas chromatography using heart cutting technique and flame ionization detection. Fuel quality specifications for this product exist, see Bibliography Entry [1].This standard is applicable to fuels having a methanol content from about 0,5 % (V/V) to about 1,5 % (V/V). Other methanol contents can also be determined, however no precision data for results outside the specified range is available.NOTEFor 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.WARNING - The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
