Water quality - Determination of biochemical oxygen demand after n days (BODn) - Part 2: Method for undiluted samples (ISO 5815:1989, modified); German version EN 1899-2:1998
This document describes a method for the empirical and conventionel determination of the biochemical oxygen demand in undiluted water samples. After preparing of the water samples and control solutions the oxygen concentration is determined by the method of DIN EN 25813 or DIN EN 25814. Afterwards the biochemical oxygen demand is computed after n days.
