Description

ASTM D5845-21

Active Standard: Standard Test Method for Determination of MTBE, ETBE, TAME, DIPE, Methanol, Ethanol and tert-Butanol in Gasoline by Infrared Spectroscopy

ASTM D5845

Scope

1.1 This test method covers the determination of methanol, ethanol, tert-butanol, methyl tert-butyl ether (MTBE), ethyl tert-butyl ether (ETBE), tert-amyl methyl ether (TAME), and diisopropyl ether (DIPE) in gasoline by infrared spectroscopy. The test method is suitable for determining methanol from 1.7 % to 5.5 % by mass, ethanol from 1.5 % to 10 % by mass, tert-butanol from 1.6 % to 12 % by mass, DIPE from 1.2 % to 17 % by mass, MTBE from 2.0 % to 16.4 % by mass, ETBE from 2.0 % to 18.5 % by mass, and TAME from 1.5 % to 18.5 % by mass.

1.2 This test method is applicable to oxygenate(s) in gasoline singularly or in multiple mixtures hereof according to the oxygenates and mass percent ranges given in 1.1.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
