ASTM D888-92(1996)

Standard Test Methods for Dissolved Oxygen in Water

SCOPE
1.1 These test methods cover the determination of dissolved oxygen in water. Two test methods are given as follows:  Range, mg/L Sections Test Method A-Titrimetric Procedure-High Level [lt]1.0 8 to 14 Test Method B-Instrumental Probe Procedure 0.05 to 20 15 to 23
1.2 The precision of Test Methods A and B was carried out using a saturated sample of reagent water. It is the user's responsibility to ensure the validity of the test methods for waters of untested matrices.  
1.3 This standard does not purport to address all of the safety problems, 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.> For a specific precautionary statement, see Note 17.
