- Scope
5.1 Methanol is used in blends with gasoline at levels of 708201;% to 858201;% by volume, as specified in Specification D5797. This test method provides a quantitative approach to measure the methanol content in methanol fuel blends, from 108201;% to 998201;% by volume. The usual concentration is 708201;% to 858201;% by volume (M70 to M85). The method is also used to analyze fuel methanol (M99) prior to blending.
1.1 This test method covers the determination of the methanol content, by gas chromatography, of M10 to M99 in methanol fuel blends, including fuel methanol (M99).
1.1.1 Methanol may be determined from 10 % to 99 % by volume.
1.2 This test method is designed to measure not only methanol in the blended gasoline but also the impurities in fuel methanol (M99) itself in the range of 5 mg/kg to 1000 mg/kg. However, not all impurities are measured nor detected by this test method.
1.2.1 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 test method.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
