    Significance and Use

    4.1 Dissolved oxygen is required for the survival and growth of many aquatic organisms, including fish. The concentration of dissolved oxygen may also be associated with corrosivity and photosynthetic activity. The absence of oxygen may permit anaerobic decay of organic matter and the production of toxic and undesirable esthetic materials in the water.

    1. Scope

    1.1 These test methods cover the determination of dissolved oxygen in water. Three test methods are given as follows:

     

    Range, mg/L

    Sections

    Test Method A—Titrimetric Procedure–
    High Level

    >1.0

     8 to 15

    Test Method B—Instrumental Probe Procedure—
    Electrochemical

    0.05 to 20

    16 to 25

    Test Method C—Instrumental Probe Procedure—
    Luminescence-Based Sensor

    0.05 to 20

    26 to 29


    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 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.4 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. For a specific precautionary statement, see Note 17.
