WebOct 1, 2007 · The copper strip corrosion test (CSCT) is used to measure the corrosivity of sulfur compounds in fluids. The CSCT is performed by immersing a strip of cleaned, polished copper in a fluid at a specified temperature for a predetermined time, then reading the strip against a standard. WebThe units of ppm and epm are commonly combined in normal reporting of water analyses, and many different constituents are frequently reported on a common unit weight basis. For example, calcium (equivalent weight 20.0) is reported in terms of "calcium as CaCO3" (equivalent weight 50.0).
