1.1These test methods2 cover the determination of soluble iodide and bromide ions, or both, in brackish water, seawater, and brines. Four test methods are given as follows:

1.1.1Test Method A for both Iodide and Bromide Ions-Volumetric, for concentrations from 0.2 mg/L to 2000 mg/L iodide and from 5 mg/L to 6500 mg/L bromide (Sections 7 - 15).

1.1.2Test Method B for Iodide Ion-Colorimetric, for concentrations from 0.2 mg/L to 2000 mg/L iodide (Sections 16 - 25).

1.1.3Test Method C for Iodide Ion-Selective electrode, for concentrations from 1 mg/L to 2000 mg/L iodide (Sections 26 - 34).

1.1.4Test Method D for Bromide Ion-Colorimetric, for concentrations from 40 mg/L to 6500 mg/L bromide (Sections 35 - 44).

1.2Test Method A is intended for use on all brackish waters, seawaters, and brines that contain appreciable amounts of iodide or bromide ions or both. Test Methods B, C, and D, because of their rapidity and sensitivity, are recommended for the analysis of brackish waters, seawaters, and brines in the field and in the laboratory.

1.3Samples containing from 0.2 mg/L to 2000 mg/L of iodide or 5 mg/L to 6500 mg/L of bromide may be analyzed by these methods.

1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.5This 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 precautionary statements, see 20.2 and 39.2.

1.6This 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.
