In the United States, oxygenate sstm and concentrations are limited to those approved under the U. For the period May 1 through Sept. It is informational only and not an official part of the standard; the full text of d48144 standard itself must be referred to for its use and application.

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. Work Item s – proposed revisions of this standard.

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.

This specification does not apply to fuels that contain an oxygenate as the primary component, such as Fuel Methanol M Note 2—Many of the values shown in Table 1 were originally developed using U. 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.

It provides for a atm of the volatility and water tolerance of automotive fuel in accordance with seasonal climatic changes at the locality where the fuel is used. Appendix X4 provides e4814 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. For a specification limit expressed as an integer, a trailing zero is significant only if the decimal point is specified.

This specification describes the various characteristics and requirements of automotive fuels for use over a wide range adtm operating conditions in ground vehicles equipped with spark-ignition engines. 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.

With regard to fuel properties, including volatility, this specification can be more or less restrictive than the EPA rules, regulations, and waivers. This abstract is a brief summary of the referenced standard.

It is the responsibility c4814 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Specification for Automotive Spark-Ignition Engine Fuel

Test Method D also includes procedures for calculating mass oxygen content and oxygenate concentration in volume percent. Historical Version s – view previous versions of standard. Values given in parentheses are provided for information only.

Consequently, the type of fuel under consideration must first be identified in order to select applicable tests. For a specification limit expressed as an integer, a trailing zero is significant only if the decimal point is specified. This standard does not purport to address all of the safety concerns, if any, associated with its use. Refer to Appendix X3 for discussions of EPA rules relating to fuel volatility, lead and phosphorous contents, deposit control additive certification, and use of oxygenates in blends with unleaded gasoline.

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. As a result, conversion of the SI values will sometimes differ slightly from the 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. However, depending on oxygenate type, as oxygenate content increases above some threshold level, the likelihood for vehicle problems also increases. All users of this specification, therefore, should refer to the latest edition.

In some cases, federal regulations specify non-SI units. The following equation is to be used to make the conversion: 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. Consequently, the type of fuel under consideration must first be identified in order to select applicable tests.

Test Method D also includes procedures for calculating mass oxygen content and oxygenate concentration in volume percent.

The significance of each of the properties of this specification is shown in Appendix X1. This convention applies to specified limits in Tables 1, 3, and Table X8.

ASTM D – 18d Standard Specification for Automotive Spark-Ignition Engine Fuel

However, in addition to the legal requirements, reformulated spark-ignition engine fuel should meet the performance requirements as well.

Refer to Appendix X3 for discussions of EPA rules relating to fuel volatility, lead and phosphorous contents, sulfur content, benzene content, deposit control additive certification, and use of oxygenates in blends with unleaded gasoline.

As a result, conversion of the SI values will sometimes differ slightly from the U. In some cases, U. Test Method D provides a procedure for determining oxygenate concentration in mass percent. Link to Active This link will always route to the current Active version of the standard.

Contact the EPA for the latest versions of the rules and additional requirements. 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. F Since DI is an index and has no units, the standard temperature conversion from U. Values given in parentheses are provided for information only. The sstm and types of c4814 are not specifically limited in this specification.

Contact the EPA for the latest versions of the rules and additional requirements. 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.

Gasolines meeting these limits are not suitable for blending with ethanol.
