Leather - Chemical determination of metal content - Part 2: Total metal content (ISO 17072-2:2022)

This document specifies a method for the determination of the total metal content in leather using digestion of the leather and subsequent determination with inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).
This method determines the total metal content in leather. It is not compound-specific or specific to the oxidation state of the metals.

Leder - Chemische Bestimmung des Metallgehaltes - Teil 2: Gesamtmetallgehalt (ISO 17072-2:2022)

Dieses Dokument legt ein Verfahren zur Bestimmung des Gesamtgehaltes von Metallen in Leder fest, indem ein Aufschluss des Leders und danach eine Bestimmung der Metalle mittels optischer Emissions-spektrometrie mit induktiv gekoppeltem Plasma (ICP-OES, en: inductively coupled plasma optical emission spectrometry), Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP-MS, en: inductively coupled plasma mass spectrometry), Atomabsorptionsspektrometrie (AAS, en: atomic absorption spectrometry) oder Atomfluoreszenzspektrometrie (SFA, en: spectrometry of atomic fluorescence) durchgeführt werden.
Dieses Verfahren bestimmt den gesamten Metallgehalt in Leder. Es ist nicht spezifisch für die jeweilige chemische Verbindung oder spezifisch für den Oxidationszustand der Metalle.
Das Verfahren ist zur Bestimmung der folgenden Metalle anwendbar:
[tabelle]
Dieses Verfahren ist außerdem zur Bestimmung von Bor (B) in Leder geeignet.
Bei chromgegerbtem Leder ist es häufig sinnvoller, ISO 5398-1, ISO 5398-2, ISO 5398-3 oder ISO 5398-4 anzuwenden.
Ringversuchsergebnisse und die mit ICP-OES erreichbaren Bestimmungsgrenzen sind in Tabelle A.1 und Tabelle A.2 angegeben.
Für die Bestimmung von Al und Ti in Leder ist in Anhang B ein Aufschlussverfahren angegeben.

Cuir - Dosage chimique des métaux - Partie 2: Teneur totale en métaux (ISO 17072-2:2022)

Le présent document spécifie une méthode de détermination de la teneur totale en métaux présents dans le cuir par digestion du cuir suivie d'une détermination par spectrométrie d'émission optique avec plasma à couplage inductif (ICP-OES), par spectrométrie de masse avec plasma à couplage inductif (ICP‑MS), par spectrométrie d'absorption atomique (AAS) ou par spectrométrie de fluorescence atomique (AFS).
Cette méthode détermine la teneur totale en métaux présents dans le cuir. Elle n'est pas spécifique à un composé ni à l'état d'oxydation des métaux.

Usnje - Kemijsko določevanje kovin - 2. del: Celotni delež kovin (ISO 17072-2:2022)

Ta dokument določa metodo za določevanje celotnega deleža kovin v usnju z uporabo razgradnje usnja in naknadnega določevanja z optično emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP-OES), masno spektrometrijo z induktivno sklopljeno plazmo (ICP-MS), atomsko absorpcijsko spektrometrijo (AAS) ali atomsko fluorescenčno spektrometrijo (SFA). Ta metoda določa skupno vsebnost kovin v usnju. Metoda ne obravnava določene spojine ali določenega oksidacijskega stanja kovin. Metoda se uporablja za določevanje naslednjih kovin: aluminij (Al), baker (Cu), kalij (K), antimon (Sb), železo (Fe), selen (Se), arzen (As), svinec (Pb), silicij (Si), barij (Ba), magnezij (Mg), natrij (Na), kadmij (Cd), mangan (Mn), kositer (Sn), kalcij (Ca), živo srebro (Hg), titan (Ti), krom (Cr) (razen usnja, ustrojenega s kromom), molibden (Mo), cink (Zn), kobalt (Co), nikelj (Ni), cirkonij (Zr). Ta metoda je primerna tudi za določanje bora (B) v usnju. Za usnja, ustrojena s kromom, je pogosto ustreznejše uporabiti standarde ISO 5398-1, ISO 5398-2, ISO 5398-3 ali ISO 5398-4. Rezultati medlaboratorijskih preskusov in omejitve kvantifikacije, ki so mogoče pri optični emisijski spektrometriji z induktivno sklopljeno plazmo, so podani v preglednicah A.1 in A.2. Za določanje aluminija in titana v usnju je v dodatku B podan postopek razgradnje.
