(Main)Copper and copper alloys - Determination of manganese content - Part 2: Flame atomic absorption spectrometric method (FAAS)
Copper and copper alloys - Determination of manganese content - Part 2: Flame atomic absorption spectrometric method (FAAS)
This European Standard specifies a flame atomic absorption spectrometric method (FAAS) for the determination of the manganese content of copper and copper alloys in the form of unwrought, wrought and cast products.
The method is applicable to products having manganese mass fractions between 0,001 0 % and 6,0 %.
Kupfer und Kupferlegierungen - Bestimmung des Mangangehaltes - Teil 2: Flammenatomabsorptionsspektrometrisches Verfahren (FAAS)
Diese Europäische Norm legt ein flammenatomabsorptionsspektrometrisches Verfahren (FAAS) für die Bestimmung des Mangangehaltes in Kupfer und Kupferlegierungen fest, die als Gussstücke oder als plastisch oder nicht plastisch geformte Produkte vorliegen.
Das Verfahren ist für Produkte mit Mangan Massenanteilen zwischen 0,001 0 % und 6,0 % anwendbar.
Cuivre et alliages de cuivre - Détermination de manganèse - Partie 2: 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 (FAAS) pour la détermination de la teneur en manganèse dans le cuivre et les alliages de cuivre sous la forme de produits non corroyés , corroyés et moulés.
Cette méthode est applicable aux produits ayant des teneurs en manganèse comprises entre 0,001 0 % et 6,0 %.
Baker in bakrove zlitine - Določevanje mangana - 2. del: Metoda s plamensko atomsko absorpcijsko spektrometrijo (FAAS)
Ta evropski standard določa metodo s plamensko atomsko absorpcijsko spektrometrijo (FAAS) za določevanje mangana v bakru in bakrovih zlitinah v negnetenih, gnetenih in ulitih izdelkih.
Metoda se uporablja za izdelke, ki vsebujejo od 0,001 % do 6,0 % masnih deležev mangana.
