Designation: D1071 − 17Standard Test Methods forVolumetric Measurement of Gaseous Fuel Samples 1This standard is issued under the f i xed 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 in 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 liquef i ed petroleum gases, inthe gaseous state at normal temperatures 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 of apparatus are listedin Table 1.1.2 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 and health practices and determine the applica-bility of regulatory limitations prior to use.1.3 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. Terminology and Units of Measurement2.1 Def i nitions: Units of Measurement—All measurementsshall be expressed in inch-pound units (that is: foot, pound(mass), second, and degrees Fahrenheit); or metric units (thatis: metre, kilogram, second, and degrees Celsius).2.2 Standard Conditions, 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 60.0°F,(2) A pressure of 14.73 psia.(3) Free of water vapor or a condition of complete water-vapor saturation as specif i ed per individual contract betweeninterested parties.2.2.2 SI Units:(1) A temperature of 288.15K (15°C).(2) A pressure of 101.325 kPa (absolute).(3) Free of water vapor or a condition of complete water-vapor saturation as specif i ed per individual contract betweeninterested parties.2.3 Standard Volume:2.3.1 Standard Cubic Foot of Gas is that quantity of gaswhich will f i ll a space of 1.000 ft 3 when under the standardconditions (2.2.1).2.3.2 Standard Cubic Metre of Gas is that quantity of gaswhich will f i ll a space of 1.000 m 3 when under the standardconditions (2.2.2).2.4 Temperature Term for Volume Reductions—For the pur-pose of 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 units.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 2.2.2.N OTE 1—The 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 be referred to the inch-pound standard conditions.3. Signif i cance and Use3.1 The knowledge of the volume of samples used in a testis necessary for meaningful results. Validity of the volumemeasurement equipment and procedures must be assured foraccurate results.4. Apparatus4.1 The various types of apparatus used for the measure-ment of gaseous fuel samples may be grouped in three classes,as shown in Table 1. References to the portions of thesemethods covering the capacity and range of operatingconditions, and the calibration, of each type are given in Table1.1 These test methods are under the jurisdiction of ASTM Committee D03 onGaseous Fuels and are the direct responsibility of Subcommittee D03.01 onCollection and Measurement of Gaseous Samples.Current edition approved April 1, 2017.
