Scope

1.1 This test method covers the determination of the ethanol content of denatured fuel ethanol by gas chromatography.

1.2 Ethanol is determined from 93 to 97 mass percent and methanol is determined from 0.1 to 0.6 mass percent. Equations used to convert these individual alcohols from mass percent to volume percent are provided.

1.3 This test method does identify and quantify methanol but does not purport to identify all individual components that make up the denaturant.

1.4 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 chromatographic values.

1.5 This test method is inappropriate for impurities that boil at temperatures higher than 225°C or for impurities that cause poor or no response in a flame ionization detector, such as water.

1.6 The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

1.7 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.
