ASTM D2392-15(2021)
(Test Method)Standard Test Method for Color of Dyed Aviation Gasolines
Standard Test Method for Color of Dyed Aviation Gasolines
SIGNIFICANCE AND USE
3.1 Aviation gasolines are dyed different colors for easy identification of grade, thus minimizing possibilities for fueling aircraft with fuel of the wrong grade.
SCOPE
1.1 This test method covers the determination of the acceptability of color of dyed aviation gasolines.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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. For specific warning statements, see Annex A1.
1.4 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.
