ASTM D1555M-22 工业芳香烃和环己烷的体积和重量计算标准测试方法[公制]

1.1 This standard is for use in calculating the weight and volume of benzene, toluene, mixed xylenes, styrene, orthoxylene, meta-xylene, para-xylene, cumene, ethylbenzene, 148.9 to 176.7 °C and 176.7 to 204.4 °C aromatic hydrocarbons, and cyclohexane. A method is given for calculating the volume at a given temperature from an observed volume at an observed temperature, t °C. Table 1 lists the density in Vacuo at 15 °F and 20 °C for chemicals used to develop the relationship. Densities (or weights) “in vacuo” represent the true density (or weight) if measured in a vacuum without the buoyancy effect of air acting on the liquid. It is representative of the actual amount of product present. Densities (or weights) “in air” represent what would be measured on a scale. The difference is on the order of 0.13 %. Modern densitometers measure density in vacuo and the ASTM recommends the use of in vacuo densities (or weights). 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 A complete inch-pound unit companion standard has been developed in Test Method D1555. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
