    Work Item: ASTM WK39644 - New Test Method for Analysis of Product Methanol (M99) and Methanol Blended (M10-M99) in Automotive Spark Ignition Fuels by Gas Chromatography

    (What is a Work Item?)

    Developed by Subcommittee: D02.04.0L | Committee D02 | Contact Staff Manager



    1. Scope

    1.1 This test method covers the determination of the methanol content of M10-M99 blends, including product fuel methanol, by gas chromatography. 1.1.1 Methanol is determined from 10 to 99 % mass or volume % in blended gasoline. 1.2 This test method is designed to measure methanol not only in the blended gasoline but also the impurities in the product methanol itself in the range of 5 to 1000 ppm (m/m). However, not all impurities are measured nor detected by this method. 1.3 Water cannot be determined by this test method and shall be measured by a procedure such as Test Method D1364 and the result used to correct the concentrations determined by this method. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    The standard is important since M85 will become in the near future a commercial fuel. It has been used for at least 15 years. However, recent discoveries of natural gas have recalled the easy pathways from natural gas to methanol. This method will be used by refineries who eventually blend gasoline and methanol at the 85 % level. Analytical laboratories as well as all those involved in the production of methanol for blending.
