This European Standard specifies a determination method of methanol in automotive ethanol (E85) fuel by capillary gas chromatography using heart cutting and flame ionisation detection. Fuel quality specifications for this product exist, see [2]. This standard is applicable to fuels having a methanol content from about 0,5 % (V/V) to about 1,6 % (V/V). The method is applicable in a wider range, from about 0,1 % (V/V) to about 2,2 % (V/V), but precision was not established over this full range. NOTE For 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, Æ. 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.
