ISO 7827:2010
Water quality -- Evaluation of the "ready", "ultimate" aerobic biodegradability of organic compounds in an aqueous medium -- Method by analysis of dissolved organic carbon (DOC)
Product Details
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.
