Abstract

Describes 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 degrees C and 101,325 kPaA, or to the equivalent mass or energy (calorific content).
