Water quality - Determination of alkalinity - Part 1: Determination of total and composite alkalinity (ISO 9963-1:1994)

Specifies a method for the titrimetric determination of alkalinity. Intended for the analysis of natural and treated water, and waste water, and can be used directly for waters having an alkalinity concentration of up to 20 mmol/l. For samples containing higher concentrations of alkalinity, a smaller test portion can be used for analysis. The recommended lower limit is 0,4 mmol/l.

Wasserbeschaffenheit - Bestimmung der Alkalinität - Teil 1: Bestimmung der gesamten und der zusammengesetzten Alkalinität (ISO 9963-1:1994)

Dieser Teil von ISO 9963 legt ein Verfahren zur titrimetrischen Bestimmung der Alkalinität fest. Es dient zur Analyse von natürlichem und behandeltem Wasser und Abwasser und kann direkt für Wasser mit einer Alkalinitätskonzentration von bis zu 20 mmol/l eingesetzt werden. Bei Proben mit höherer Alkalinitätskonzentration kann ein kleineres Aliquot zur Analyse verwendet werden. Die empfohlene Nachweisgrenze ist 0,4 mmol/l. Suspendierte Stoffe in Form von Carbonaten können die Analyse stören.

Qualité de l'eau - Détermination de l'alcalinité - Partie 1: Détermination de l'alcalinité totale et composite (ISO 9963-1:1994)

La présente partie de l'ISO 9963 prescrit une méthode pour la détermination titrimétrique de l'alcalinité. Elle est destinée à l'analyse de l'eau naturelle et traitée, de l'eau résiduaire et peut être directement utilisée pour les eaux ayant une concentration d'alcalinité jusqu'à 20 mmol/l. Pour les échantillons contenant des concentrations supérieures d'alcalinité, il convient de prendre une portion d'essai plus faible pour l'analyse. La limite inférieure est de 0,4 mmol/l. Les matières en suspension sous forme de carbonate peuvent interférer avec l'analyse. Cette interférence peut être réduite par filtration avant le titrage. La détection du point de virage à l'aide d'un pH-mètre est moins sujette aux interférences que l'usage d'un indicateur.

Foreword
IS0 (the International Organization for Standardization) is a worldwide
federation of national standards bodies (IS0 member bodies). The work
of preparing International Standards is normally carried out through IS0
technical committees. Each 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, governmental
and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard IS0 9963-l was prepared by Technical Committee
ISOnC 147, Water quality, Subcommittee SC 2, Physical, chemical,
biochemical methods.
IS0 9963 consists of the following parts, under the general title INater
