ASTM D2791-19 PDF

Scope: 1.1 This test method covers the on-line determination of trace amounts of sodium in water using an ion-selective electrode. 1.2 This test method is based on on-line application of the sodium ion electrode as reported in the technical literature (1-3).2 It is generally applicable over the range of 0.01 to 10 000 µg/L. 1.3 The analyst should be aware that adequate collaborative data for precision and bias statements as required by Practice D2777 are not provided. See Section 16 for details. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see Section 6. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
