ASTM D512-04

Standard Test Methods for Chloride Ion In Water

SIGNIFICANCE AND USE
Chloride ion is under regulation in water, and must, therefore, be measured accurately. It is highly detrimental to high-pressure boiler systems and to stainless steel, so monitoring is essential for prevention of damage. Chloride analysis is widely used as a tool for estimating the cycles of concentration, such as in cooling tower applications. Processing waters and pickling solutions used in the food processing industries also require dependable methods of analysis for chloride.
SCOPE
1.1 These test methods cover the determination of chloride ion in water, wastewater (Test Method C only), and brines. The following three test methods are included:SectionsTest Method A (Mercurimetric Titration)7 to 14Test Method B (Silver Nitrate Titration)15 to 21Test Method C (Ion-Selective Electrode Method)22 to 29
1.2 Test Methods A, B, and C were validated under Practice D2777 - 77, and only Test Method B conforms also to Practice D 2777 - 86. Refer to Sections 14, 21, and 29 for further information.
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 and health practices and determine the applicability of regulatory limitations prior to use. For a specific hazard statement, see 26.1.1.
1.4 A former colorimetric test method was discontinued. Refer to Appendix X1 for historical information.
