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. Contact the EPA for the latest versions of the rules and additional requirements.
ASTM D – 11b Standard Specification for Automotive Spark-Ignition Engine Fuel
Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1. For a specified limit expressed as an integer, and the right-most digit is non-zero, the right-most digit is awtm without a decimal point being specified. A0 Standards Related Products 1. A0 Standards Related Products. This specification does not apply to fuels that contain an oxygenate as the primary component, such as Fuel Methanol M 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.
In the United States, oxygenate types and concentrations are limited to those approved under the U. Work Item s – proposed revisions of this standard.
Link to Active D8414 link will always route to the current Active version of the standard. It provides for a variation of the volatility and water tolerance of automotive fuel in accordance with seasonal climatic changes at the locality where the fuel is used. Values given in parentheses are provided for information only.
Test Method D also includes procedures for calculating mass oxygen content and oxygenate concentration in volume percent.

Values given in parentheses are provided for information only. 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. Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1.
Test Method D provides a procedure for determining oxygenate awtm in mass percent. It provides for a variation of the volatility and water tolerance of automotive fuel in accordance with seasonal climatic changes at the locality where the fuel is ast.
As a result, conversion of the SI values will sometimes differ slightly from the U. However, depending on oxygenate type, as oxygenate content increases above some threshold level, the likelihood for vehicle problems also increases.
Standard Specification for Automotive Spark-Ignition Engine Fuel
Contact the EPA asstm the latest versions of the rules and additional requirements. Note 2—Many of the values 4d814 in Table 1 were originally developed using U. All users of this specification, therefore, should refer to the latest edition. The following equation is to be used to make the conversion: However, in addition to the legal requirements, reformulated spark-ignition engine fuel should meet the performance requirements as well.
For a specification limit expressed as an integer, a trailing zero is significant only if the decimal point is specified.
This abstract is a brief summary of the referenced standard. F Since DI is an index and has no units, the standard temperature conversion from U. Historical Version s – view previous versions of standard.
This convention applies to specified limits in Tables 1, 3, and Table X8. 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. 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 specification is under continuous review, which can result in revisions based on changes in fuel, automotive requirements, or test methods, or a combination thereof.
In some cases, federal regulations specify non-SI units. The concentrations and types of oxygenates are not specifically limited in this specification. 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.
In some cases, U.
