1. Scope | ||||||||||||
1.1?This standard is for use in calculating the weight and volume of benzene, toluene, mixed xylenes, styrene, ortho-xylene, 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 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. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
