Significance and Use3.1 This test method is suitable for use in calculatingweights and volumes of th
8、e products outlined in Section 1. Theinformation presented in this method can be used for deter-mining quantities of the above-stated aromatic hydrocarbons intanks, shipping containers, etc.4. Basic Data4.1 Densities of pure materials at 60F are derived fromdensities furnished by NSRDS-NIST 75-121 (
9、National Stan-dard Reference Data SeriesNational Institute of Standardsand Technology). Densities of impure materials should bedetermined by actual measurement (see Section 7).4.2 The VCF (Volume Correction Factor) equations pro-vided below were derived from the Volume Correction Tablespresented in
10、the previous edition of this standard, MethodD 1555-95. Although reported as based on the AmericanPetroleum Institute Research Project 44, the actual documen-tation that could be found is incomplete. As regression of theNIST data (Appendix X1) provided VCFs that differ from thehistorical VCFs by onl
11、y 0 to 6 0.12 % (depending on thecompound), the decision was made to use the previous meth-ods VCF tables.4.3 The VCF tables were regressed with a commerciallyavailable data regression program (TableCurve 2D V4). How-ever, any modern regression program should produce the sameresults.4.4 The former V
12、CF tables were based on data for com-pounds of the highest purity, but were reported to be usable formaterials in the ranges indicated in Table 2. The data support-ing this conclusion appears to be unavailable at the presenttime; however there is no reason to change this recommenda-tion. If, dependi

21、he nearest 0.1 degree Fahrenheitat which the bulk volume was measured (temperature t). Afterperforming the mathematical operations, round the resultingVCF to 5 places past the decimal. Multiply the bulk volumemeasurement at temperature t by the VCF.NOTE 1The purchaser and seller should agree on a re
22、asonable policyin regard to rounding of final numbers in all computations. Rounding thefinal weight or volume to five significant figures is, in most cases, alsoacceptable.6.1.1 Example 1What is the volume at 60F of a tank carof p-xylene whose volume was measured to be 9280 gal at amean temperature
23、of 88.7F?6.1.1.1 Enter Eq 1 with 88.7 and the appropriate constantsfrom Table 3 to calculate a VCF of 0.98414. The volume at60F is:9280 0.98414 5 9132.8 gal6.2 Converting Volume to Weight for Chemicals Listed inTable 1Multiply the volume in gallons at 60F (5 digits) bythe appropriate density in poun

25、as described in 6.1. Determinethe density (all weights in vacuo) at 60F in grams per millilitre(or grams per cubic centimetre, they are equivalent) as de-scribed in Section 7. To obtain the density in pounds per gallonin vacuo, multiply by the factor described in footnote C ofTable 1. To obtain the
26、density in pounds per gallon in air at60F, use the equation described in footnote D of Table 1 (orrefer to Appendix X3).6.3.1 Example 3If the p-xylene in Example 2 is less than100 % pure, its density should be determined by actualmeasurement. For instance, if the p-xylene is 95 % pure and itsdensity
27、 has been measured and determined to be 0.8651 g/mL(in vacuo) at 60F, the density in lb/gal is:0.8651 8.34540438! 5 7.2196 lb/gal in vacuoor0.8651 1.00014992597 0.00119940779543! 8.345404385 7.2107 lb/gal in airThe weight of the net volume is thus:9132.8 7.2196 65,935 lb in vacuoor9132.8 7.2107 5 65
