Copper and copper alloys - Determination of antimony content - Part 1: Spectrophotometric method

This part of this European Standard specifies a Rhodamine B spectrophotometric method for the determination of the antimony content of copper and copper alloys in the form of unwrought, wrought and cast products.
The method is applicable to products having antimony mass fractions in the range between 0,001 % and 0,1 %, or greater by appropriate modification of the mass of the test portion, the volume of the test portion solution to be taken for the extraction and the cell path length.

Kupfer und Kupferlegierungen - Bestimmung des Antimongehaltes - Teil 1: Spektrophotometrisches Verfahren

Dieser Teil dieser Europäischen Norm legt ein spektrophotometrisches Verfahren mit Rhodamin B für die Bestimmung
des Antimongehaltes in Kupfer und Kupferlegierungen fest, die als Gussstücke oder als plastisch oder
nicht plastisch geformte Produkte vorliegen.
Das Verfahren ist geeignet für Produkte mit Antimon-Massenanteilen zwischen 0,001 % und 0,1 % oder größer,
wenn entsprechende Änderungen der Probenmasse, des Volumens der Probenlösung für die Extraktion und der
Küvettenlänge vorgenommen werden.

Cuivre et alliages de cuivre - Dosage de l'antimoine - Partie 1 : Méthode spectrophotométrique

Cette partie de la présente Norme européenne spécifie une méthode spectrophotométrique à la rhodamine B pour le dosage de l’antimoine dans le cuivre et les alliages de cuivre sous la forme de produits non corroyés, corroyés et coulés.
La méthode s’applique aux produits ayant des teneurs en antimoine comprises entre 0,001 % et 0,1 %, ou supérieures en modifiant de manière appropriée la masse de la prise d’essai, le volume de solution pour essai à prélever pour l’extraction et la longueur du parcours optique de la cuve.
