ASTM D8234-19 PDF

Scope: 1.1 This test method covers the simultaneous determination of fluoride (F− ), nitrite-N (NO2-N), ortho-phosphate-P (o-PO4P), bromide (Br− ), nitrate-N (NO3-N), and sulfate (SO4 -2 ) ions in high saline water (up to 20 % sodium chloride (NaCl)) by suppressed ion chromatography and tandem ultra-violet (UV) detection. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.2.1 Exception—The inch-pound and SI units shown for pressure measurements are to be individually regarded as standard. 1.3 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. 1.4 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.
