Dear customer,

Please note that the EI publishing department has moved to a new print supplier for 2021. The option to purchase Hard Copies of our publications has been suspended until the New Year, when we will be making select areas of the catalogue available again.

This standard is intended to guide the user through the steps necessary to calculate static liquid quantities, at atmospheric conditions, in upright, cylindrical tanks and marine tank vessels. The standard defines terms employed in the calculation of static petroleum quantities.

The standard also specifies equations that allow the values of some correction factors to be computed. Fundamental to this process is the understanding that in order for different parties to be able to reconcile volumes, they have to start with the same basic information (tank capacity table, levels, temperatures, and so forth), regardless of whether the information is gathered automatically or manually.

This standard does not address the calculation of clingage, non-liquid material, small quantities (such as onboard quantities, quantities remaining on board, and wedge formula, where material is not touching all bulkheads on marine vessels), and vapor space calculations.
