ASTM D1555-21

Active Standard: Standard Test Method for Calculation of Volume and Weight of Industrial Aromatic Hydrocarbons and Cyclohexane

ASTM D1555

Scope

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, 300 to 350Ā°F and 350 to 400Ā°F aromatic hydrocarbons, and cyclohexane. A method is given for calculating the volume at a desired temperature tbĀ°F from an observed volume at toĀ°F. Table 1 lists the density in Vacuo at 60Ā°F for chemicals used to develop the relationship. Densities (or weights) ā€œin vacuoā€ 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) ā€œin airā€ represent what would actually be measured on a scale. The difference is on the order of 0.13ā€‰%. Modern densitometers measure density in vacuo and the ASTM recommends the use of in vacuo densities (or weights).

1.2 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1 A complete SI unit companion standard has been developed in Test Method D1555M.

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.
