Standard Practice for Handling of High Purity Water Samples
N D4453
Annotation
This practice2 covers concepts for handling high purity water samples needed for the measurement of ever-decreasing levels of specified impurities that are encountered in the operation of modern high-pressure boilers and turbines. The handling of blanks associated with the analysis of high purity water samples is also covered by this practice. The techniques presented can help the investigator increase the accuracy of analyses performed.
This practice is applicable to water and steam samples from “zero solids treated” once-through or drum-type boilers, reactor coolant water, electronic grade water, or any other process water where analyte concentrations are in the low parts per billion (micrograms per litre) range.
The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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. Specific hazards statements are given in 6.2.3.5, 6.1, and 6.3.7.
2 This practice suggests the use of specific techniques. As new techniques are developed or required by lower limits, revision of this practice will likely be needed.
