This standard specifies general test methods for the determination of trace moisture in fluoroolefins for refrigerants, including the Karl Fischer coulometry and the electrolysis method. The standard applies to the determination of moisture in fluoroolefins, but the electrolysis method does not apply to fluoroolefins for low pressure refrigerants. The standard describes in detail the sampling equipment and methods, including cylinder sampling of fluoroolefins for medium and high voltage refrigerants and glass bottle sampling of fluoroolefins for low pressure refrigerants. It also specifies the material requirements of the sampling conduit, as well as the specific operation steps for sampling and processing, to ensure the accuracy of the test results.
