5.1 Dissolved oxygen is detrimental in certain boiler and steam cycles because it may accelerate corrosion. Concentrations above 10 µg/L are unacceptable in many high-pressure boiler systems. The efficiency of dissolved oxygen removal from boiler feedwater by chemical or...
This specification covers a naval shipboard, method C, water testing dissolved oxygen kit using an organic dye for the determination of dissolved oxygen in feedwater.
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...
1.1 This test method covers the on-line determination of dissolved oxygen (DO) in water samples primarily in ranges from 0 to 500 µg/L (ppb), although higher ranges may be used for calibration. On-line instrumentation is used for continuous measurements of DO in samples that are...
These test methods cover the determination of dissolved oxygen in water. 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. The...
This method is for determining dissolved oxygen in concentrations as low as 0.1 mass-ppm in liquefied petroleum gases, and in aqueous or organic solutions, including caustic, liquid hydrocarbons, glycols and phenols. The determination of combined oxygen is not within the scope...

ISO 17289:2014 specifies an optical method for the determination of dissolved oxygen in water using a sensor working on the basis of fluorescence quenching. Measurement can be made either as a concentration of oxygen in milligrams per litre, percentage saturation (%...
This International Standard specifies an optical method for the determination of dissolved oxygen in water using a sensor working on the basis of fluorescence quenching. Measurement can be made either as a concentration of oxygen in milligrams per litre, percentage saturation...
ISO 5814:2012 specifies an electrochemical method for the determination of dissolved oxygen in water by means of an electrochemical cell which is isolated from the sample by a gas permeable membrane. Measurement can be made either as a concentration of oxygen in milligrams per...
This test method covers the rapid determination of low-level (<100 μg/L) dissolved oxygen in thermal-cycle steam condensate, deaerated boiler feedwater, boiler water, and deaerated deionized water. Color comparators allow the estimation of concentrations ranging from 0 to 100 μg/L...
