1、Designation: D1250 08 (Reapproved 2013)Designation: 200/08Standard Guide forUse of the Petroleum Measurement Tables1This standard is issued under the fixed designation D1250; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year

2、 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.This standard has been approved for use by agencies of the Department of Defense.INTRODUCTIONThis guide discusses the use of t

3、emperature and pressure volume correction factors for generalizedcrude oils, refined products, and lubricating oils, developed jointly by ASTM International, theAmerican Petroleum Institute (API) and the Energy Institute.2The volume correction factors, in their basic form, are the output of a set of

4、 equations derived from,and based on, empirical data relating to the volumetric change of hydrocarbons over a range oftemperatures and pressures. Traditionally, the factors have been listed in tabular format called thePetroleum Measurement Tables (hence the appearance of this term in the title), and

5、 published as anAPI Standard/Adjunct to IP 200/Adjunct to ASTM D1250. However, since the 1980 revision theactual standard has been a set of implementation procedures, not printed tables nor simply a set ofequations.This revised standard, API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTM

6、D125004 (ADJD1250CD), establishes procedures for crude oils, liquid refined products, andlubricating oils, by which volume measurements taken at any temperature and pressure (within therange of the standard) can be corrected to an equivalent volume at base/standard conditions, normally15C, 60F or 20

7、C, by use of a volume correction factor (VCF). The standard, API MPMS Chapter11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004 (ADJD1250CD), also providesmethods for making conversions to alternate conditions from base conditions and to alternate basetemperatures. Densities can be corrected by u

8、sing the inverse of the VCF.See Section 5 for a list of significant changes from Guide D125080 (provided in its entirety inAnnex A13).USAGE GUIDELINESThe revised standard, API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004 (ADJD1250CD), is effective upon the date of publication an

9、d supersedes the previousedition of the standard/adjunct(s). However, due to the nature of the changes in the revisedstandard/adjunct(s), it is recognized that guidance concerning an implementation period may beneeded in order to avoid disruptions within the industry and ensure proper application. A

10、s a result, itis recommended that the revised standard/adjunct(s) be used on all new applications no later than twoyears after the publication date (May 2004). An application for this purpose is defined as the pointwhere the calculation is applied.Once the revised standard/adjunct(s) is implemented

11、in a particular application, the previousstandard will no longer be used in that application.If an existing application complies with the previous standard/adjunct(s) (as referenced in AnnexA13), then it shall be considered in compliance with the revised standard/adjunct(s).However, the use of the A

12、PI MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTMD125004 (ADJD1250CD) remains voluntary, and the decision on when to utilize a standard is anissue that is subject to the negotiations between the parties involved in the transaction.Copyright ASTM International, 100 Barr Harbor Drive, PO B

13、ox C700, West Conshohocken, PA 19428-2959. United States12007 UPDATESome minor modifications to the API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct toASTM D125004 (ADJD1250CD) have been issued inAddendum 1-2007. These modifications to theadjunct necessitated a realignment with ASTM Standard G

14、uide D1250, hence an -07 version has beenapproved and published.1. Scope1.1 The API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004 (ADJD1250CD) for tempera-ture and pressure volume correction factors for generalizedcrude oils, refined products, and lubricating oils, provides thea

15、lgorithm and implementation procedure for the correction oftemperature and pressure effects on density and volume ofliquid hydrocarbons. Natural gas liquids (NGLs) and liquefiedpetroleum gases (LPGs) are excluded from consideration. Thecombination of density and volume correction factors for bothtem

16、perature and pressure is collectively referred to in thestandard/adjunct(s) as a Correction for Temperature and Pres-sure of a Liquid (CTPL). The temperature portion of thiscorrection is termed the Correction for the effect of Tempera-ture on Liquid (CTL), also historically known as VCF (VolumeCorre

17、ction Factor). The pressure portion is termed the Correc-tion for the effect of Pressure on Liquid (CPL).As this standardwill be applied to a variety of applications, the output param-eters specified in this standard/adjunct(s) (CTL, Fp, CPL, andCTPL) may be used as specified in other standards.1.2

18、Including the pressure correction in API MPMS Chapter11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004(ADJD1250CD) represents an important change from the“temperature only” correction factors given in the 1980 Petro-leum Measurement Tables. However, if the pressure is oneatmosphere (the standard

19、 pressure) then there is no pressurecorrection and the standard/adjunct(s) will give CTL valuesconsistent with the 1980 Petroleum Measurement Tables.1.3 API MPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct to ASTM D125004 (ADJD1250CD) covers generalprocedures for the conversion of input data to ge

20、nerate CTL,Fp, CPL, and CTPL values at the user specified base tempera-ture and pressure (Tb, Pb). Two sets of procedures are includedfor computing volume correction factor: one set for dataexpressed in customary units (temperature in F, pressure inpsig); the other for the metric system of units (te

21、mperature inC, pressure in kPa or bar). In contrast to the 1980 PetroleumMeasurement Tables, the metric procedures require the proce-dure for customary units be used first to compute density at60F. This value is then further corrected to give the metricoutput. The metric procedures now incorporate t

22、he basetemperature of 20C in addition to 15C.1.4 The procedures recognize three distinct commoditygroups: crude oil, refined products, and lubricating oils. Aprocedure is also provided for determining volume correctionfor special applications where the generalized commoditygroups parameters may not

23、adequately represent the thermalexpansion properties of the liquid and a precise thermalexpansion coefficient has been determined by experiment.2.

Also shown in Table 1 are thelimits converted to their equivalent units (and, in the case of thedensities, other base temperatures).4.2 Note that only the preci

35、sion levels of the defining valuesshown in Table 1 are correct. The other values showingconverted units have been rounded to the significant digitsshown; as rounded values, they may numerically fall justoutside of the actual limits established by the defining values.4.3 Table 2 provides a cross-refe

36、rence between the histori-cal table designations and the corresponding section in APIMPMS Chapter 11.12004/Adjunct to IP 200/04/Adjunct toASTM D125004 (ADJD1250CD). Note that procedure para-graphs 11.1.6.3 (U.S. customary units) and 11.1.7.3 (metricunits) provide methods for correcting on-line densi

38、he temperature isdifferent from that at which the hydrometer was calibrated. The1980 CTL Tables had generalized equations to correct glasshydrometer readings, and these corrections were part of theprinted odd-numbered tables.

40、 to IP 200/04/Adjunct to ASTM D125004(ADJD1250CD) is intended for use with petroleum fluidscomprising either crude oils, refined products, or lubricatingoils that are single-phase liquids under normal operatingconditions. The liquid classifications listed here are typicalterms used in the industry,

41、but local nomenclature may vary.The list is illustrative and is not meant to be all-inclusive.4.6 Crude OilsA crude oil is considered to conform to thecommodity group Generalized Crude Oils if its density falls inthe range between approximately 10API to 100API. Crudeoils that have been stabilized fo

42、r transportation or storagepurposes and whose API gravities lie within that range areconsidered to be part of the Crude Oil group. Also, aviation jetB (JP-4) is best represented by the Crude Oil correlation.4.7 Refined ProductsA refined product is considered toconform to the commodity group of Gener

43、alized RefinedProducts if the fluid falls within one of the refined productgroups. Note the product descriptors are generalizations. Thecommercial specification ranges of some products may placetheir densities partly within an adjacent class (for example, alow density diesel may lie in the jet fuel

44、class). In such cases,the product should be allocated to the class appropriate to itsdensity, not its descriptor. The groups are defined as follows:4.7.1 GasolineMotor gasoline and unfinished gasolineblending stock with a base density range between approxi-mately 50API and 85API. This group includes
