Water quality - Determination of free chlorine and total chlorine - Part 1: Titrimetric method using N, N-diethyl-1,4-phenylenediamine (ISO 7393-1:1985)

Specifies a procedure for water. Sea water and waters containing bromides and iodides comprise a group for which special procedures are required. The procedure is applicable to concentrations, in terms of chlorine, from 0,000 4 to 0,07 mmol/l total chlorine and at higher concentrations by dilution of samples. Several compounds influencing the procedure are noted.

Wasserbeschaffenheit - Bestimmung von freiem Chlor und Gesamtchlor - Teil 1: Titrimetrisches Verfahren mit N,N-Diethyl-1,4-Phenylendiam (ISO 7393-1:1985)

Dieser Teil von ISO 7393 legt ein titrimetrisches Verfahren zur Bestimmung von freiem Chlor und Gesamtchlor in Wasser fest. Meerwasser sowie bromid- und iodidhaltiges Wasser bilden eine Gruppe, für die besondere Verfahren erforderlich sind. Das Verfahren ist zur Bestimmung von Chlor (Cl2) in Konzentrationsbereichen von 0,000 4 mmol/l bis 0,07 mmol/l (0,03 mg/l bis 5 mg/l) Gesamtchlor geeignet; bei höheren Konzentrationen müssen die Proben verdünnt werden. Bei Konzentrationen über 0,07 mmol/l kann auch ISO 7393-3 angewendet werden.

Qualité de l'eau - Dosage du chlore libre et du chlore total - Partie 1: Méthode titrimétrique à la N,N-diéthylphénylène-1,4-diamine (ISO 7393-1:1985)

La présente partie de l'ISO 7393 spécifie une méthode titrimétrique pour le dosage du chlore libre et du chlore total dans l'eau.L'eau de mer et les eaux contenant des bromures et des iodures  constituent un groupe pour lequel des procédés particuliers sont nécessaires. [2] La méthode est applicable à des concentrations en chlore total, exprimées en chlore (Cl2) de 0,000 4 à 0,07 mmol/l (0,03 à 0,07 mmol/l, l'ISO 7393/3 peut être aussi utilisée.Dans l'annexe A, un mode opératoire est décrit pour la différenciation du chlore combiné du type monochloramine, du chlore combiné du type dichloramine, et du chlore combiné sous la forme de trichlorure d'azote. Plusieurs composés influencent le dosage décrit dans la présente partie de l'ISO 7393. Les interférences sont indiquées dans les chapitres 7 et 9.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of
national Standards bodies (ISO member bedies). The work of preparing International
Standards is normally carried out through ISO technical committees. Esch member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for approval before their acceptance as International Standards by
the ISO Council. They are approved in accordance with ISO procedures requiring at
least 75 % approval by the member bodies voting.
International Standard ISO 7393/1 was prepared by Technical Committee
ISO/TC 147, Water quality.
