Significance and Use

4.1 These test methods are applicable for such purposes as impurity detection and, in some cases, the quantitative measurement of ionic constituents dissolved in waters. These include dissolved electrolytes in natural and treated waters, such as boiler water, boiler feedwater, cooling water, and saline and brackish water.

4.1.1 Their concentration may range from trace levels in pure waters (2)⁴ to significant levels in condensed steam (see Test Methods D2186 and D4519, and Ref 4.1.2 Where the principal interest in the use of conductivity methods is to determine steam purity, see Ref 1.1 These test methods cover the determination of the electrical conductivity and resistivity of water. The following test methods are included:

Range

Test Method A—Field and Routine Laboratory

10 to 200 000

Measurement of Static (Non-Flowing) Samples

μS/cm

Test Method B—Continuous In-Line Measure

5 to 200 000

19 to 23

1.2 These test methods have been tested in reagent water. It is the user's responsibility to ensure the validity of these test methods for waters of untested matrices.

1.3 For measurements below the range of these test methods, refer to Test Method D5391.

1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 and health practices and determine the applicability of regulatory limitations prior to use.
