ASTM D6504-00
Standard Practice for On-Line Determination of Cation Conductivity in High Purity Water
1.1 This practice describes continuous sample conditioning by hydrogen ion exchange and measurement by electrolytic conductivity. It is commonly known as cation conductivity measurement in the power industry although it is actually an indication of anion contamination in high purity water samples. Measurements are typically in a range less than 1 S/cm.
1.2 The actual conductivity measurements are made using Test Method D 5391.
1.3 This practice does not provide for separate determination of dissolved carbon dioxide. Refer to Test Methods D 2186 and D 4519.
