Standard Test Method for Calculation of Volume and Weight of Industrial Aromatic Hydrocarbons (Metric)
|Publication Date:||10 January 2000|
|ICS Code (Aromatic hydrocarbons):||71.080.15|
The tables in this test method cover calculating the weight and volume of benzene, toluene, mixed xylenes, styrene, o-xylene, m-xylene, p-xylene, cumene, ethylbenzene, 148.9 to 176.7°C (300 to 350°F) aromatic hydrocarbons, 176.7 to 204.4°C (350 to 400°F) aromatic hydrocarbons, and cyclo-hexane. A procedure is given for calculating the volume at 15.0°C from an observed volume at t°C. Table 1 lists the density in kilograms per litre at 15.0°C for high purity chemicals.
A procedure for the calculation of density in kilograms per litre at 15.0°C of materials of lower purity is provided.
NOTE 1 - The purchaser and the seller should agree on a reasonable policy in regard to rounding of final numbers in all computations. Rounding the final weight or volume to not more than five significant digits is, in most cases, consistent with the experimental reliability of the data.
NOTE 2 - An alternative test method is Test Method D 4052.
This test method is the SI companion of Test Method D 1555.
The following applies to all specified limits in this test method: for purpose of determining conformance with this test method, an observed value or calculated value shall be rounded off "to the nearest unit" in the last right-hand digit used on expressing the specification limit, in accordance with the rounding-off method of Practice E 29.
