ASTM D1555-2016 工业芳烃和环己烷体积和重量计算的标准测试方法
ASTM D1555 标准适用于计算第 2 节中概述的产品的重量和体积 1. The information provided in this method can be used to determine the amount of the above-mentioned aromatics in tanks, transport containers, ETC.
意义及用途
3.1 This test method is suitable for calculating the weight and volume of the product outlined in Section 1. The information provided in this method can be used to determine the amount of the above-mentioned aromatics in tanks, transport containers, ETC.
步 1: 范围
1.1 This standard is used to calculate the weight and volume of benzene, toluene, mixed xylene, 苯乙烯, o-xylene, m-xylene, p-xylene, isopropylbenzene, ethylbenzene, 300 to 350°F and 350 to 400°F aromatics hydrocarbons and cyclohexane. A method for calculating the volume of 60°F from the observed volume at t °F is presented. 桌子 1 lists the Vacuo densities of the chemicals used to develop this relationship at 60°F. 密度 (or weight) “in vacuum” represents the true density (or weight) if measured in a vacuum without the buoyancy action of air acting on a liquid. It represents the number of products that actually exist. 密度 (or weight) “in the air” represents what is actually measured to scale. The difference is about 0.13 percent. Modern densitometers measure density in a vacuum, and ASTM recommends using vacuum density (or weight).

(A) Regression based on the 2001 TRC Thermodynamic Table, Hydrocarbons, NSRDS-NIST 75-121 (April 30, 2001). See Appendix X1 for data.
(乙) The weight was removed from the table because it was not required by the criterion. 如果需要的话, divide the 60°F density (g/cc) by 0.999016 g/cc. See Appendix X2.
(C) produced by multiplying the density at 60°F by g/cc by 8.345404452 and rounding to 4 decimal places.
(D) Use density -g/cc to produce in air ·1.000149926-0.001199407795) ·8.345404452, rounded to 4 decimal places. See Appendix X3.
