Specifies the so-called Winkler procedure modified in order to make allowance for certain interferences. It is the reference procedure and applicable to all types of water having concentrations greater than 0,2 mg/l, up to double saturation, which are free from interfering substances.
Abstract
Overview
EN 25813:1992, titled "Water quality - Determination of dissolved oxygen - Iodometric method ()," is a European Standard developed by CEN. It specifies a modified Winkler titration procedure for the accurate determination of dissolved oxygen in water. This iodometric method is the reference standard for quantifying dissolved oxygen concentrations ranging from 0.2 mg/l up to double saturation, approximately 20 mg/l, in waters free of interfering substances.
