ステップ 1: 範囲

1.1 This standard is used to calculate the weight and volume of benzene, トルエン, mixed xylene, スチレン, o-xylene, m-xylene, p-xylene, isopropylbenzene, ethylbenzene, aromatic hydrocarbons and cyclohexane from 148.9 to 176.7°C and 176.7 to 204.4°C. A method for calculating the volume at 15 ° C and 20 ° C from the observed volume at t ° C is presented. テーブル 1 lists the Vacuo densities of the chemicals used to develop this relationship at 60°F. Density (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. Density (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).

(あ) Obtained from method D1555-04a by multiplying the 60°F density of the chemical by a volume correction factor of 59°F.

(B) Specific gravity at 15°C is not shown in this table because it is not required by this standard. If desired, divide the 15 ° C density (g/cc) by 0.999102g/cc. See Appendix X1.

(C) g/cc can be multiplied by 1000 to convert to kg / 1000L or kg/m 3.

(D) Prepared using the following equation: Density g/mL in air = (1.000149926× density g/mL in vacuum – 0.001199407795) and rounded to 5 decimal places. See Appendix X2.

(E) Obtained from method D1555-04a by multiplying the 60°F density of the chemical by a volume correction factor of 68°F.

(F) Specific gravity at 20°C is not shown in this table because it is not required by this standard. If desired, divide the 20 ° C density (g/cc) by 0.998206g/cc. See Appendix X1.
