【摘要】:ThisInternationalStandarddefinesthefollowingquantitiescommonlyusedtoexpressthecompositionofgasmixtures:—molefraction,—massfraction,—volumefraction,and—moleconcentration,—massconcentration,—volumeconcentration.Forthesequantitiesofcomposition,thisInternationalStandardprovidesmethodsfor—conversionbetweendifferentquantities,and—conversionbetweendifferentstateconditions.Conversionbetweendifferentquantitiesmeanscalculatingthenumericalvalueofananalytecontentintermsofoneofthequantitieslistedabovefromthenumericalvalueofthesameanalytecontent,atthesamepressureandtemperatureofthegasmixture,givenintermsofanotherofthesequantities.Conversionbetweendifferentstateconditionsmeanscalculatingthenumericalvalueofananalytecontent,intermsofoneofthequantitieslistedabove,underonesetofstateconditionsfromthenumericalvalueofthesamequantityunderanothersetofstateconditions,i.e.pressureandtemperature,ofthegasmixture.Gasmixturecompositioncanbeconvertedsimultaneouslybetweendifferentquantitiesofcompositionanddifferentstateconditionsbycombinationofthetwotypesofconversion.ThisInternationalStandardisapplicableonlytohomogeneousandstablegasmixtures.Thereforeanystateconditions(pressureandtemperature)consideredneedtobewelloutsidethecondensationregionofthegasmixtureandthatofeachofthespecifiedanalytes(seeAnnexA).
