Diese Europäische Norm legt ein flammenatomabsorptionsspektrometrisches Verfahren (FAAS) für die
Bestimmung des Nickelgehaltes in Kupfer und Kupferlegierungen fest, die als Gussstücke oder als plastisch
oder nicht plastisch geformte Produkte vorliegen.
Das Verfahren ist geeignet für Produkte mit einem Nickel-Massenanteil zwischen 0,001 % und 6,0 %.

Cuivre et alliages de cuivre - Détermination du nickel - Partie 3: Méthode par spectrométrie d'absorption atomique dans la flamme (SAAF)

La présente Norme européenne spécifie une méthode par spectrométrie d’absorption atomique dans la
flamme (SAAF) pour la détermination du nickel dans le cuivre et les alliages de cuivre, sous forme de produits
non corroyés, corroyés et moulés.
La méthode est applicable aux produits ayant des teneurs (fraction en masse) en nickel comprises
entre 0,001 % et 6,0 %.

Baker in bakrove zlitine - Določevanje niklja - 3. del: Metoda s plamensko atomsko absorpcijsko spektrometrijo (FAAS)

Ta evropski standard določa metodo z uporabo spektrometrije s plamensko atomsko absorpcijo (FAAS) za določevanje niklja v bakru in bakrovih zlitinah v obliki negnetenih, gnetenih in ulitih polizdelkov. Metoda velja za polizdelke z masnim deležem niklja med 0,001 % in 6.0 %.

4.4 Lanthanum (III) chloride solution, 100 g/l. Dissolve 50 g of lanthanum (III) chloride heptahydrate (LaCl3 · 7H2O) in a 400 ml beaker with water and transfer the solution into a 500 ml one-mark volumetric flask. Dilute to the mark with water and mix. 4.5 Nickel stock solution, 1,0 g/l Ni. Weigh (1 ± 0,001) g of nickel (Ni ≥ 99,8 %) and transfer it into a 250 ml beaker. Add 10 ml of hydrochloric acid (4.1) and 10 ml of the nitric acid solution (4.3). Cover with a watch glass and, if necessary, heat gently to assist dissolution. When dissolution is complete, cool to room temperature and transfer the solution quantitatively into a 1 000 ml one-mark volumetric flask, dilute to the mark with water and mix. 1 ml of this solution contains 1,0 mg of Ni. 4.6 Nickel standard solution, 0,1 g/l Ni.

7.1.3 Nickel mass fractions between 0,01 % and 0,25 % Weigh (1 ± 0,001) g of the test sample. Transfer the test portion into a 250 ml beaker. Add 5 ml of hydrochloric acid (4.1) and 10 ml of the nitric acid solution (4.3). Cover with a watch glass and heat gently until the test portion is completely dissolved. Cool to room temperature. Wash the beaker cover and the sides of the beaker with water. Transfer the dissolved test portion quantitatively into a 100 ml one-mark volumetric flask. Add 10 ml of the lanthanum (III) chloride solution (4.4). Dilute to the mark with water and mix. NOTE The validation exercise of this standard method showed that for nickel mass fractions between 0,2 % and 0,25 % results are better when the determination is carried out following 7.1.3. 7.1.4 Nickel mass fractions between 0,2 % and 6,0 % Weigh (1 ± 0,001) g of
