ASTM-D6504 › Standard Practice for On-Line Determination of Cation Conductivity in High Purity Water
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
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 μS/cm.
1.2 The actual conductivity measurements are made using Test Method .
1.3 This practice does not provide for separate determination of dissolved carbon dioxide. Refer to Test Method .
1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
