Clear liquids - Estimation of colour by the platinum-cobalt scale - Part 2: Spectrophotometric method (ISO 6271-2:2004)
ISO 6271-2:2004 specifies a spectrophotometric method for estimating the colour, in Pt-Co units, of clear liquids. It is applicable to clear liquids having a colour characteristic similar to those of the reference platinum-cobalt scale specified in ISO 6271-1, which describes a visual method.
The method described provides a more precise way of measuring Pt-Co colour than that described in ISO 6271-1.
Klare Flüssigkeiten - Bestimmung der Farbe nach der Platin-Cobalt-Skala - Teil 2: Spektralphotometrisches Verfahren (ISO 6271-2:2004)
Dieser Teil von ISO 6271 legt ein spektralphotometrisches Verfahren zum Einstufen der Farbe von klaren Flüssigkeiten nach der Platin-Cobalt-Farbskala fest. Er ist anwendbar auf klare Flüssigkeiten, die eine ähnliche Farbcharakteristik wie die in ISO 6271-1 festgelegte Platin-Cobalt-Farbskala besitzen.
Das beschriebene Verfahren erlaubt es, die Platin-Cobalt-Farbzahl genauer zu messen als in ISO 6271-1 beschrieben wird.
ANMERKUNG Die hier verwendete Benennung "Platin-Cobalt-Farbzahl" wird den Benennungen "Hazen-Farbzahl" und "APHA-Farbzahl" vorgezogen
Liquides clairs - Evaluation de la couleur au moyen de l'échelle platine-cobalt - Partie 2: Méthode spectrophotométrique (ISO 6271-2:2004)
L'ISO 6271-2:2004 spécifie une méthode spectrophotométrique pour l'évaluation de la couleur, en unités de l'échelle platine-cobalt, des liquides clairs. Elle est applicable aux liquides clairs ayant des caractéristiques de couleur proches de celles de l'échelle de référence Pt-Co spécifiée dans l'ISO 6271-1.
La méthode décrite fournit une méthode plus fidèle pour mesurer la couleur Pt-Co que celle décrite dans l'ISO 6271-1.
