BS ISO 6578:2017

This standard BS ISO 6578:2017 Refrigerated hydrocarbon liquids. Static measurement. Calculation procedure is classified in these ICS categories:

• 75.180.30 Volumetric equipment and measurements

This document specifies the calculation procedure to convert the volume of liquefied petroleum gas (LPG) and liquefied natural gas (LNG) under the conditions at the time of measurement to the equivalent volume of liquid or vapour at the standard condition, i.e. 15 °C and 101,325 kPaA, or to the equivalent mass or energy (calorific content). It applies to the quantities of refrigerated hydrocarbon liquids stored in or transferred to/from tanks and measured under static storage conditions. Calculation of pressurized gases is out of the scope of this document.
