The ASTM D888 standard, developed by the American Society for Testing and Materials (ASTM), provides three test methods for the determination of dissolved oxygen in water:

The full name of this standard is: ASTM D888-18 Standard test methods for dissolved oxygen in water.
Dissolved oxygen is necessary for the survival and growth of many aquatic organisms, including fish. Dissolved oxygen concentration is also correlated with etching and photosynthetic activity. The absence of oxygen causes the anaerobic decomposition of organic matter and the production of toxic and undesirable aesthetic materials in water.
The precision of test methods A and B is performed using a saturated sample of reactive water.
Dissolved oxygen refers to the level of free, uncompounded oxygen found in water or other liquids and is an important parameter in assessing water quality. Dissolved oxygen is an important factor in the study of lakes, second only to water itself. Too high or too low dissolved oxygen levels harm aquatic life and adversely affect water quality.
In the tests and analyzes carried out in our organization, which has a wide range of technological equipment, trained and experienced staff and applies the most modern methods, national and international standards and legal regulations in force are complied with. Dissolved oxygen determination (ASTM D888) services are among the numerous tests performed in this context.
