All users of this specification, therefore, should refer to the latest edition. Values given in parentheses are provided for information only. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine 4d814 applicability of regulatory limitations prior to use. The spark-ignition engine fuels covered here are gasoline and its blends with oxygenates, such as alcohols and ethers, and not fuels that d414 an oxygenate as the primary component, such as fuel methanol M The concentrations and types of oxygenates are not specifically limited in this specification.
This convention applies to specified limits in Tables 1, 3, and Table X8.
The significance of each of the properties of this specification is shown in Appendix X1. Consequently, the type of fuel under consideration must first be identified in order to select applicable tests. This specification does not address the emission characteristics of reformulated spark-ignition engine fuel.

H 2 However, in addition to the legal requirements, reformulated spark-ignition engine fuel should meet the performance requirements as well. Many of the values shown in Table 1 were originally developed using U.
In many countries, regulatory authorities having jurisdiction have set laws and regulations that limit the concentration of oxygenates and certain other compounds found in spark-ignition engine fuel.
Work Item s – proposed revisions of this standard. Gasolines meeting these limits are not suitable for d48144 with ethanol. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
For the period May 1 through Sept. Historical Version s – view previous versions of standard. 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.
Standard Specification for Automotive Spark-Ignition Engine Fuel
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. As a result, conversion of the SI values will sometimes differ slightly from the U. For a specification limit expressed as an integer, a v4814 zero is significant only if the decimal point is specified.
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. 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.
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. All users of this specification, therefore, should refer to the latest edition. 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.
ASTM D – 18d Standard Specification for Automotive Spark-Ignition Engine Fuel
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. Refer to Appendix X3 for discussions of EPA rules relating to fuel volatility, lead and asrm contents, sulfur content, benzene content, 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. This specification does not apply to fuels that contain an oxygenate as the primary component, such as Fuel Methanol M Variation of the antiknock index with seasonal climatic changes and altitude is discussed in Appendix X1.
Active view current version of 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. In some cases, federal regulations specify non-SI units. In addition, the composition of unleaded fuel is subject to the rules, regulations, and Clean Air Act v4814 of the U. With regard to fuel properties, including volatility, this specification can be more or less restrictive than the EPA rules, regulations, and waivers.
