Significance and Use

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 (1)4 to significant levels in condensed steam (see Test Methods D 2186 and D 4519, and Ref (2)), or pure salt solutions.

4.1.2 Where the principal interest in the use of conductivity methods is to determine steam purity, see Ref (3). These test methods may also be used for checking the correctness of water analyses (4).

Scope

1.1 These test methods cover the determination of the electrical conductivity and resistivity of water. The following test methods are included:

RangeSections
Test Method A-Field and Routine Laboratory10 to 200 000 12 to 18
Measurement of Static (Non-Flowing) Samplesμ S/cm
Test Method B-Continuous In-Line Measure 5 to 200 00019 to 23
mentμ S/cm

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 D 5391.

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.

1.4 This test method is applicable to field and routine laboratory measurements of the electrical conductivity of water using static samples.

1.5 This test method is applicable to the continuous, in-line measurement of the electrical conductivity of water.
