EN ISO 7827:2012 "Water quality - Evaluation of the ""ready""@ ""ultimate"" aerobic biodegradability of organic compounds in an aqueous medium - Method by analysis of dissolved organic carbon (DOC)"
"This International Standard specifies a method for the evaluation of the ""ready"" and ""ultimate"" biodegradability of organic compounds at a given range of concentrations by aerobic microorganisms. In this context@ this International Standard also gives specific definitions for the terms ""ready"" and ""ultimate"". The method applies to organic compounds which are: a) soluble at the concentration used under the conditions of the test [dissolved organic carbon (DOC) concentrations of 10 mg/l to 40 mg/l]; b) non-volatile or having a negligible vapour pressure under the conditions of the test; c) not significantly adsorbable on glass and activated sludge; d) not inhibitory to the test microorganisms at the concentration chosen for the test. The method is not suitable for waste waters@ as they usually contain significant amounts of water-insoluble organic carbon@ which is not included in DOC measurements."
