This standard provides a method for determining the volume and weight of industrial aromatics such as benzene, toluene, mixed Xylene, and cyclohexane at different temperatures. The method enables accurate calculation of the actual amounts of these chemicals in containers or transport containers. Detailed Correction factors and calculation formulas are provided by converting the volume observation data at different temperatures into the volume and weight at standard temperatures (15 ° C and 20 ° C). The standard recommends the use of density values measured in vacuum to ensure accuracy, thus providing reliable data support in practical applications.
