ASTM D5798

This specification covers a fuel blend, nominally 75 to 85 volume % denatured fuel ethanol (Ed75-Ed85) and 25 to 15 additional volume % hydrocarbons for use in ground vehicles with automotive spark-ignition engines. Fuel ethanol (Ed75-Ed85) shall conform to the performance requirements prescribed. Fuel ethanol (Ed75-Ed85) shall be visually free of sediment and suspended matter. The hydrocarbon/aliphatic ether blend content, vapour pressure, acidity, pH requirements, gum content, inorganic chloride, water requirements, copper requirements, and sulphur requirements shall be tested to meet the requirements prescribed.

It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1. Scope

1.1 This specification covers a fuel blend, nominally 75 to 85 volume % denatured fuel ethanol and 25 to 15 additional volume % hydrocarbons for use in ground vehicles with automotive spark-ignition engines. Appendix X1 discusses the significance of the properties specified.

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

The following safety hazards caveat pertains only to the test method portion, Annex A1, 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 and health practices and determine the applicability of regulatory limitations prior to use.
