Designation:D358898(Reapproved 2017)1Standard Practice forCalculating Heat Value,Compressibility Factor,and RelativeDensity of Gaseous Fuels1This standard is issued under the fixed designation D3588;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTENote 2 was editorially corrected in April 2020.1.Scope1.1 This practice covers procedures for calculating heatingvalue,relative density,and compressibility factor at baseconditions(14.696 psia and 60F(15.6C)for natural gasmixtures from compositional analysis.2It applies to all com-mon types of utility gaseous fuels,for example,dry natural gas,reformed gas,oil gas(both high and low Btu),propane-air,carbureted water gas,coke oven gas,and retort coal gas,forwhich suitable methods of analysis as described in Section 6are available.Calculation procedures for other base conditionsare given.1.2 The values stated in inch-pound units are to be regardedas the standard.The SI units given in parentheses are forinformation only.1.3 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:3D1717 Test Method for Test for Analysis of CommericalButane-Butene Mixtures and Isolutylene by Gas
