1、Designation:D107117Standard Test Methods forVolumetric Measurement of Gaseous Fuel Samples1This standard is issued under the fixed designation D1071;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number i
2、n parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 These test methods cover the volumetric measuring ofgaseous fuel samples,including liquefied petroleum gases,inthe gaseous state at normal temperat
3、ures and pressures.Theapparatus selected covers a sufficient variety of types so thatone or more of the methods prescribed may be used forlaboratory,control,reference,or in fact any purpose where it isdesired to know the quantity of gaseous fuel or fuel samplesunder consideration.The various types o
4、f apparatus are listedin Table 1.1.2This 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 and health practices and determine the applica-bility of regulatory limitations

7、nditions,at which gaseous fuel samplesshall be measured,or to which such measurements shall bereferred,are as follows:2.2.1 Inch-pound Units:(1)A temperature of 60.0F,(2)A pressure of 14.73 psia.(3)Free of water vapor or a condition of complete water-vapor saturation as specified per individual cont
8、ract betweeninterested parties.2.2.2 SI Units:(1)A temperature of 288.15K(15C).(2)A pressure of 101.325 kPa(absolute).(3)Free of water vapor or a condition of complete water-vapor saturation as specified per individual contract betweeninterested parties.2.3 Standard Volume:2.3.1 Standard Cubic Foot
9、of Gas is that quantity of gaswhich will fill a space of 1.000 ft3when under the standardconditions(2.2.1).2.3.2 Standard Cubic Metre of Gas is that quantity of gaswhich will fill a space of 1.000 m3when under the standardconditions(2.2.2).2.4 Temperature Term for Volume ReductionsFor the pur-pose o
10、f referring a volume of gaseous fuel from one tempera-ture to another temperature(that is,in applying Charles law),the temperature terms shall be obtained by adding 459.67 toeach temperature in degrees Fahrenheit for the inch-poundunits or 273.15 to each temperature in degrees Celsius for theSI unit
11、s.2.5 At the present state of the art,metric gas provers andmeters are not routinely available in the United States.Throughout the remainder of this procedure,the inch-poundunits are used.Those having access to metric metering equip-ment are encouraged to apply the standard conditions ex-pressed in
12、2.2.2.NOTE1The SI conditions given here represent a“hard”metrication,in that the reference temperature and the reference pressure have beenchanged.Thus,amounts of gas given in metric units should always bereferred to the SI standard conditions and the amounts given in inch-poundunits should always b
