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

Общепринятая практика для обработки высокочистых проб воды

Этот practice2 покрывает понятия для обработки высоких проб воды чистоты, необходимых для измерения когда-либо уменьшающихся уровней указанных примесей, с которыми встречаются в эксплуатации современных бойлеров с высоким давлением и турбин. Обработка пробелов, связанных с анализом высоких проб воды чистоты, также покрыта этой практикой. Представленные методы могут помочь следователю увеличить точность выполняемых исследований
