.5.1:2009(R2020) 第一部分 60°F时的API重度换算

Provides implementation procedures for conversion of API gravity at 60 °F to equivalent densities in both in vacuo and in air values. This standard gives the following equivalents for any value of API gravity at 60 °F: — relative density at 60 °F (old Table 3); — absolute density at 60 °F; — absolute density at 15 °C (old Table 3); — pounds per U.S. gallon at 60 °F in vacuo and in air (old Table 8); — U.S. gallons per pound at 60 °F in vacuo and in air (old Table 8); — short tons per 1000 U.S. gallons at 60 °F in vacuo and in air (old Table 9); — U.S. gallons per short ton at 60 °F in vacuo and in air (old Table 10); — short tons per barrel at 60 °F in vacuo and in air (old Table 9); — barrels per short ton at 60 °F in vacuo and in air (old Table 10); — long tons per 1000 U.S. gallons at 60 °F in vacuo and in air (old Table 11); — U.S. gallons per long ton at 60 °F in vacuo and in air (old Table 12); — long tons per barrel at 60 °F in vacuo and in air (old Table 11); — barrels per long
