1.1 This practice covers the information on calibration, quality control, and operational guidance for anionic measurements using ion chromatography (IC).

1.2 IC Related Standards-Chemically or electrolytically regenerated suppressed ion chromatography standards for aqueous matrices include Test Methods D2988, D4327, D5085, D5542, D5827, D5987, D5996, D6581, D7319, D7328, D7359, D7773, D7994, and D8150; IC instrumentation requirements are described in Practices E1151, and E1511.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 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.

1.5 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.
