This International Standard specifies methods suitable for the determination of ammonium nitrogen in various
types of waters (such as ground, drinking, surface, and waste waters) in mass concentrations ranging from
0,1 mg/l to 10 mg/l (in the undiluted sample), applying either FIA (Clause 3) or CFA (Clause 4). In particular
cases, the range of application may be adapted by varying the operating conditions.
