These Petroleum Measurement Tables2 are for use in the calculation of quantities of crude petroleum and petroleum products at required conditions in any of three widely used systems of measurement. Tables are provided over normal operating ranges for the reduction of gravity and volume to standard states@ for calculation of weight-volume relationships@ and interconversion of a wide variety of commercially useful units. The tables@ issued in three volumes@ cover United States@ British@ and Metric systems of measurement. Note 1- These tables supersede ASTM d 206@ Abridged Volume Correction Tables@ and ASTM D 1090. Tentative Factors and Tables for Volume Correction and Specific Gravity Conversion of Liquefied Petroleum Gases. Because of the broader range of values covered@ and the larger number of individual tables provided@ these tables replace the National Bureau of Standards Circular C-410@ and the Supplement thereto ( Abridged Volume Correction Table for Petroleum Oils)@ which were with drawn form circulation by the NBS effective January 1@ 1954.
