The specification is under continuous review, which can result in revisions based on changes in fuel, automotive requirements, or test methods, or a combination thereof. It provides for a variation of the volatility and asmt tolerance of automotive fuel in accordance with seasonal climatic changes at the locality where the fuel is used.
H 2 The concentrations and types of oxygenates are not specifically limited v4814 this specification. In the United States, oxygenate types and concentrations are limited to those approved under the U.
Standard – Standard Specification for Automotive Spark-Ignition Engine Fuel ASTM D –
Gasolines meeting these limits are not suitable for blending with ethanol. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and satm the applicability of d481 limitations prior to use. Test Method D also includes procedures for calculating mass oxygen content and oxygenate concentration in volume percent.

Refer to Appendix X3 for discussions of EPA 4d814 relating to fuel volatility, lead and phosphorous contents, deposit control additive certification, and use of oxygenates in blends with unleaded gasoline.
Contact the EPA for the latest versions of the rules and additional requirements. All users of this specification, therefore, should refer to the latest edition. A0 Standards Related Products.
For a specified limit expressed as an integer, and the right-most digit is non-zero, the right-most digit is significant without a decimal point being specified. A0 Standards Related Products 1. For the period May 1 through Sept. For a specification limit expressed as an integer, a trailing zero is significant only if the decimal point is specified.
Work Item s – proposed revisions of this standard. It is informational only and not an official part of the standard; asm full text of the standard itself must be d8414 to for its use and application.
Values given in parentheses are provided for information only. Many of the values shown in Table 1 were originally developed using U.
However, in addition to the legal requirements found in this research report, reformulated spark-ignition engine fuel should meet the performance requirements found in this specification. 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.
Reformulated spark-ignition engine fuel is required in some areas to lower emissions from automotive vehicles, and its characteristics are described in the research report on reformulated spark-ignition engine fuel.
ASTM D – 18d Standard Specification for Automotive Spark-Ignition Engine Fuel
Appendix X4 provides a procedure for calculating the mass oxygen content of a fuel using measured oxygenate type, oxygenate concentration in volume percent, and measured density or relative density of the fuel. Consequently, the type of fuel under consideration must first be identified in order to select applicable tests. This specification neither necessarily includes all types of fuels that are satisfactory for automotive vehicles, nor necessarily excludes fuels that can perform unsatisfactorily under certain operating conditions or in certain equipment.
Work Item s – proposed revisions of this standard. With regard to fuel properties, including asym, this specification can be more or less restrictive than the EPA rules, regulations, and waivers.
This specification describes the various characteristics and requirements of automotive fuels for use over a wide range of operating conditions in ground vehicles equipped with spark-ignition engines.
In some cases, U.
The spark-ignition engine fuels covered here are gasoline and its blends with oxygenates, such as alcohols and ethers, and not fuels that contain an oxygenate as the primary component, such as fuel methanol M The composition of both unleaded and leaded fuel is limited by economic, legal, and technical consideration, but their properties, including volatility, are defined by this specification.
Reformulated spark-ignition engine fuel is required in some areas to lower emissions from automotive vehicles, and its characteristics are described in the research report on reformulated spark-ignition engine fuel. Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1. This convention applies to specified limits in Tables 1, 3, and Table X8. This specification does not address the emission characteristics of reformulated spark-ignition engine fuel.
Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1. As a result, conversion of the SI values will sometimes differ slightly from the U.
