This part of ISO 6570 specifies a volumetric method for the determination of the potential hydrocarbon liquid content of natural gas.
This method permits simultaneous determination of the amount of water that condenses under the conditions of the test.
The principles of, and general requirements for, methods for the determination of potential hydrocarbon liquid content are specified in ISO 6570/1. An alternative weighing method for the determination of potential hydrocarbon liquid is specified in ISO 6570/2.
