This document specifies a method for the determination of nitrate as NO3-N in water of various origin such as natural water (including groundwater, surface water and bathing water), drinking water and wastewater, in a measuring range of concentration between 0,20 mg/l and 30 mg/l of NO3-N using the small-scale sealed tube method. Different measuring ranges of small-scale sealed tube methods can be required.
