ASTM D1125-23 PDF

Scope: 1.1 These test methods cover the determination of the electrical conductivity and resistivity of water. The following test methods are included: Range Sections Test Method A—Field and Routine Laboratory 10 to 200 000 12 to 18 Measurement of Static (Non-Flowing) Samples µS/cm Test Method B—Continuous In-Line Measure 5 to 200 000 19 to 23 ment µS/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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 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.
