Water quality - Examination and determination of colour (ISO 7887:1994)
Cancels and replaces the first edition (1985). Specifies three methods for the examination of colour: a method for the examination of apparent colour by visually observing a water sample in a bottle; a method for the determination of the true colour of a water sample using optical apparatus; a method for the determination of the colour by visual comparison with hexachloroplatinate standard solutions. Under certain circumstances, strongly coloured water samples need to be diluted before examination or determination.
Wasserbeschaffenheit - Untersuchung und Bestimmung der Färbung (ISO 7887:1994)
Diese internationale Norm beschreibt die Verfahren zur Bestimmung der Färbung: Hauptabschnitt 2 beschreibt ein Verfahren zur Bestimmung der Färbung durch Betrachtung einer Wasserprobe in einem Behälter. Damit wird nur eine vorläufige Information erhalten, beispielsweise bei Untersuchungen vor Ort. DasErgebnis kann nur als "scheinbare Färbung" angegeben werden. Hauptabschnitt 3 beschreibt ein Verfahren zur Bestimmung der Färbung einer Wasserprobe mit Hilfeeines optischen Gerätes. Das Verfahren ist auf Roh- und Trinkwasser und auf schwach gefärbtes Industrieabwasser anwendbar. Störungen siehe Abschnitt 3.3.
Qualité de l'eau - Examen et détermination de la couleur (ISO 7887:1994)
La présente Norme internationale prescrit trois méthodes d'examen de la couleur : La section 2 prescrit une méthode d'examen de la couleur apparente par observation visuelle d'un échantillon d'eau dans une bouteille. Cela donne une première indication, par exemple sur le terrain. Seule la couleur apparente peut être indiquée. La section 3 prescrit une méthode de détermination de la couleur vraie d'un échantillon d'eau au moyen d'un appareillage d'optique, et peut être appliquée aux eaux brutes et potables, et aux eaux industrielles faiblement colorées. Pour les interférences, voir 3.3. La section 4 prescrit une méthode de détermination de la couleur par comparaison visuelle avec des solutions étalons d'hexachloroplatinate et peut être appliquée aux eaux brutes et potables. Pour les interférences, voir 4.2. Dans certaines circonstances, des échantillons d'eaux fortement colorés nécessitent d'être dilués avant examen ou détermination. Dans le rapport d'essai, il est absolument nécessaire de mentionner la méthode utilisée.
