(Main)Leather - Chemical determination of metal content - Part 2: Total metal content (ISO 17072-2:2011)
Leather - Chemical determination of metal content - Part 2: Total metal content (ISO 17072-2:2011)
This standard specifies a method for the determination of total metals in leather using extraction with an acid artificial perspiration solution and subsequent determination with either Inductively Coupled Plasma – Optical Emission Spectrometry (ICP-OES) or Atomic Absorption Spectrometer (AAS).
This method is especially used to determine the extractable chromium in chromium tanned leathers.
Leder - Chemische Bestimmung des Metallgehaltes - Teil 2: Gesamtmetallgehalt (ISO 17072-2:2011)
1.1 Diese Norm legt ein Verfahren zur Bestimmung des Gehalts sämtlicher Metalle in Leder fest, wobei ein Aufschluss des Leders und danach eine Bestimmung der Metalle mittels optischer Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP OES), mittels Massenspektrometrie mit induktiv gekoppeltem Plasma (ICP MS) oder mittels Atomabsorptionsspektrometrie (AAS) durchgeführt werden.
Dieses Prüfverfahren besteht in einer Analyse des gesamten Metallgehalts in Leder; es ist nicht spezifisch für die jeweilige chemische Verbindung oder spezifisch für den Oxidationszustand der Metalle.
Cuir - Détermination chimique de la teneur en métal - Partie 2: Teneur totale en métaux (ISO 17072-2:2011)
L'ISO 17072-2:2011 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), ou par spectrométrie d'absorption atomique (AAS), ou par spectrométrie de masse avec plasma à couplage inductif (ICP-MS), ou par spectrométrie de fluorescence atomique (SFA).
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.
La méthode s'applique à la détermination des métaux suivants: aluminium (Al), antimoine (Sb), arsenic (As), baryum (Ba), cadmium (Cd), calcium (Ca), chrome (Cr), cobalt (Co), cuivre (Cu), fer (Fe), plomb (Pb), magnésium (Mg), manganèse (Mn), mercure (Hg), molybdène (Mo), nickel (Ni), potassium (K), sélénium (Se), silicium (Si), sodium (Na), étain (Sn), titane (Ti), zinc (Zn) et zirconium (Zr).
La limite de quantification du plomb total est de 8 mg/kg.
L'ISO 17072-2:2011 ne s'applique pas aux cuirs tannés au chrome. Dans ce cas, l'ISO 5398-1, l'ISO 5398-2, l'ISO 5398-3 ou l'ISO 5398-4 sont utilisées.
Usnje - Kemijsko določevanje kovin - 2. del: Celotni delež kovin (ISO 17072-2:2011)
Ta standard določa metodo za določevanje skupnih kovin v usnju z izločevanjem s kislo raztopino za umetno perspiracijo in nato z določevanjem z optično emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP-OES) ali z atomskim absorpcijskim spektrometrom (AAS).
Ta metoda se uporablja predvsem za določevanje izločljivega kroma v vrstah usnja, barvanih s kromom.

ISO 17072-2:2011(E) IULTCS/IUC 27-2:2011(E) iv © ISO 2011 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 17072-2 was prepared by the European Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, in collaboration with the Chemical Test Commission of the International Union of Leather Technologists and Chemists Societies (IUC Commission, IULTCS), in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). This method is technically similar to the method in IUC 27-2. IULTCS, originally formed in 1897, is a world-wide organization of professional leather societies to further the advancement of leather science and technology. IULTCS has three Commissions, which are responsible for establishing international methods for the sampling and testing of leather. ISO recognizes IULTCS as an international standardizing body for the preparation of test methods for leather. ISO 17072 consists of the following parts, under the general title Leather — Chemical determination of metal content: ⎯ Part 1: Extractable metals ⎯ Part 2: Total metal content SIST EN ISO 17072-2:2011
INTERNATIONAL STANDARD ISO 17072-2:2011(E)IULTCS/IUC 27-2:2011(E) © ISO 2011 – All rights reserved 1 Leather — Chemical determination of metal content — Part 2: Total metal content 1 Scope This part of ISO 17072 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), or inductively coupled plasma/mass spectrometry (ICP/MS), or 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. The method is applicable for determining the following metals: Aluminium (Al) Copper (Cu) Potassium (K) Antimony (Sb) Iron (Fe) Selenium (Se) Arsenic (As) Lead (Pb) Silicon (Si) Barium (Ba) Magnesium (Mg) Sodium (Na) Cadmium (Cd) Manganese (Mn) Tin (Sn) Calcium (Ca) Mercury (Hg) Titanium (Ti) Chromium (Cr) (except chromium-tanned leathers)Molybdenum (Mo) Zinc (Zn) Cobalt (Co)
