This International Standard describes the principles of, and general requirements for, two gravimetric methods for
the determination of the potential hydrocarbon liquid content of natural gas, or similar gas, at a given pressure and
temperature. Two methods are specified in this International Standard to determine the amount of condensate in a
_ Method A: a manual weighing method;
_ Method B: an indirect automatic weighing method based on the indication of the pressure difference caused by
the accumulation of condensate in a vertical tube.
The manual weighing method is a reference method for the indirect automatic method (Method B). The indirect
automatic method (Method B) is suitable for semi-continuous control.
NOTE Unless otherwise specified, gas volumes are in cubic metres at 273,15 K and 101,325 kPa.
