This European Standard specifies a determination method of methanol in automotive ethanol (E85) fuel (also designated as ethanol (E85) automotive fuel or shortly “E85”) by capillary gas chromatography using heart cutting technique. 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.
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, φ.
WARNING — The use of this standard can involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of users of this standard to take appropriate measures to ensure the safety and health of personnel prior to application of the standard, and fulfil statutory and regulatory requirements for this purpose.
