(Test Method)Standard Test Method for Calculation of Volume and Weight of Industrial Aromatic Hydrocarbons and Cyclohexane
Standard Test Method for Calculation of Volume and Weight of Industrial Aromatic Hydrocarbons and Cyclohexane
SIGNIFICANCE AND USE
This test method is suitable for use in calculating weights and volumes of the products outlined in Section 1. The information presented can be used for determining quantities of the above-stated aromatic hydrocarbons in tanks, shipping containers, etc.
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, 300 to 350F and 350 to 400F aromatic hydrocarbons, and cyclohexane. A method is given for calculating the volume at 60F from an observed volume at tF. lists the density in pounds per gallon at 60F for high purity chemicals.
1.2 Calculated results shall be rounded off in accordance with the rounding-off method of Practice E 29.
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 and health practices and determine the applicability of regulatory limitations prior to use.
