NACE TM0374-2016

Provides a relative and quantitative measure of the abilities of scale inhibitors to prevent the precipitation of solids, a necessary and critical stage in the formation of scale. Describes static laboratory screening tests designed to give a measure of the ability of inhibitors to prevent the precipitation of calcium carbonate and calcium sulfate from solution at 71 °C (160 °F). The test methods are recommended only for ranking the performance of different chemicals under laboratory conditions set by these methods. They are not intended to provide actual field treating rates.
