Active Standard: D5173 - 97(2007)
Rationale: Title changed to electrical conductivity to be consistent with the D1125 conductivity method used in TOC measurement techniques included here. 1.Scopereformatted into tabular form for easy identification of oxidation techniques. Ranges changed to include current instrument capabilities. 2.Referenced documentseliminated D4779 which has been withdrawn. 3.Terminologyelectrical conductivity added to be consistent with D1125 conductivity method. 4,5 Miscellaneous changes for clarification; interference covered in section 6. 6. Interferencesclarified for the various oxidation and detection techniques. 8. Reagents and materialsupdated to describe current pure water availability and cleaning techniques. 11. Calibration and Proceduremiscellaneous changes for clarification. 13. New quality control section required for D19 standards. Figuresretitled for clarity and identification in Table 1 and updated notes to reflect current instrument operation.
