ASTM D 4806 : 2025

1.1This specification covers nominally anhydrous denatured fuel ethanol. This material is normally used as a blendstock in applications such as ASTM Specifications D4814, D5798, and D8076. The material may be also used as a fuel in engines and vehicles specifically equipped for its use. The significance of each of the properties in this specification is shown in Appendix X1.

1.2Jurisdictions may vary in their regulatory requirements for the allowable or prohibited types of denaturants, chemical composition of the denaturant or concentration of denaturant needed to denature the ethanol. The user is advised to check with the national and regional regulatory agencies where the ethanol is denatured and used.

1.3The values stated in SI units are to be regarded as standard.

1.4The following safety hazards caveat pertains only to the method modification in 8.7 of this specification: 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.

1.5This 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.
