Scope

1.1 This method provides for the determination of the ethanol content of denature fuel ethanol by gas chromatography. 1.2 This method docs identify and quantify methanol but does not purport to identify all individual components that make up the denaturant. 13 Water cannot be determined by this test method and must be measured by a procedure such as ASTM D 1364 and the result used to normalize the chromatographicvalues. 1.4 SI (metric units) of measurement are preferred and used throughout the standard. Values stated in units of other systems are provided for clarity and to aid the users of this method. 13 This standard may involve hazardous materials, operations, andequipment. This standard does notpurport to address allofthe safetyproblems associatedwith its use. It is the responsibility ofthe user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.1 This method provides for the determination of the ethanol content of denatured fuel ethanol by gas chromatography. 1.2 This method does identify and quantify methanol but does not purport to identify all individual components that make up the denaturant. 1.3 Water cannot be determined by this test method and must be measured by a procedure such as ASTM D 1364 and the result used to normalize the chromatographic values. 1.4 SI (metric units) of measurement are preferred and used throughout the standard. Values stated in units of other systems are provided for clarity and to aid the users of this method. 1.5 This test method is inappropriate for impurities which boil at temperatures higher than 225° C or for impurities which cause poor or no response in a flame ionization detector, such as water. 1.6 This standard may 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 the user of this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.1 This method provides for the determination of the ethanol content of denatured fuel ethanol by gas chromatography. 1.2 Ethanol is determined from 93 to 97 mass% and methanol is determined from 0.1 to 0.6 mass%. Equations used to convert these individual alcohols from mass% to volume% are provided. 1.3 This 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 must be measured by a procedure such as ASTM D 1364 and the result used to correct the chromatographic values. 1.5 This test method is inappropriate for impurities which boil at temperatures higher than 225° C or for impurities which 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 problems, 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. 1.1 This method provides for the determination of the ethanol content of denatured fuel ethanol by gas chromatography. 1.2 This method does identify and quantify methanol but does not purport to identify all individual components that make up the denaturant. 1.3 Water cannot be determined by this test method and must be measured by a procedure such as ASTM D 1364 and the result used to normalize the chromatographic values. 1.4 SI (metric units) of measurement are preferred and used throughout the standard.
