1.1 This specification guides in establishing the requirements of gasoline for ground vehicles equipped with sparkignition engines. 1,2 This specification describes various characteristics of gasolinesfor use over a wide rangeof operatingconditions. It provides for a variation of the volatility of gasoline in accordance with seasonal climatic changes at the locality where the gasoline is used. It neithernecessarily includes all types of gasolines that are satisfactoryfor automotive vehicles, nor necessarily excludes gasolines that may perform unsatisfactorily under certain operating conditions or in certain equipment. The significance of this specification is shown in Appendix X1 .
1.3 Gasoline is not the only fuel used in ground vehicles equippedwith spark-ignitionengines.Blendsofgasolinewith oxygenates such as alcohols and ethers are common in the marketplace. However, some of the test methods referred to in this specification are not applicable to such blends, A specification that encompasses all fuels for automotive spark-ignition engines has -been developed. It appears as Specification D 4814. Refer to Specification D 4814 for information and for requirements and test methods applicable to gasoline-oxygenateblends.
1.4 This specificationrepresentsa descriptionof gasolines as of the date of publication. T.he specification is under continous review, which may result in revisions based on changesin gasoline or automotiverequirements,or both. A i l users of this specification,therefore, should refer to the latest edition. NOTE1-If there is anydoubt asto the latestedition of Specification D 439, contact ASTM Headquarters.
