Water quality. Guidance for determination of biodegradability in the marine environment1 Scope This International Standard specifies five methods for determining the ultimate aerobic biodegradability of organic compounds in the marine environment by aerobic microorganisms in static aqueous test systems. Standard degradation methods developed for testing in fresh water are modified and adapted to marine conditions. These methods are the DOC die away test (ISO 7827), the closed bottle test (ISO 10707), the two phase closed bottle test
