Leather - Chemical determination of metal content - Part 1: Extractable metals (ISO 17072-1:2011)
ISO 17072-1:2011 specifies a method for the determination of extractable metals in leather using extraction with an acid artificial-perspiration solution and subsequent determination with inductively coupled plasma/optical emission spectrometry (ICP-OES), or inductively coupled plasma/atomic emission spectrometry (ICP/AES), or inductively coupled plasma/mass spectrometry (ICP/MS), or atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).
This method is especially suitable for determining the extractable chromium in chromium tanned leathers.
This method determines extractable metals in leather, it is not compound-specific or specific to the oxidation state of the metals.
This method is also applicable for the determination of many extractable metals, including aluminium (Al), antimony (Sb), arsenic (As), barium (Ba), cadmium (Cd), calcium (Ca), chromium (Cr), cobalt (Co), copper (Cu), iron (Fe), lead (Pb), magnesium (Mg), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), potassium (K), selenium (Se), tin (Sn), titanium (Ti), zinc (Zn), and zirconium (Zr).
The quantification limit of extractable lead is 3 mg/kg.
Leder - Chemische Bestimmung des Metallgehaltes - Teil 1: Extrahierbare Metalle (ISO 17072-1:2011)
Dieser Teil von ISO 17072 legt ein Verfahren zur Bestimmung der Gehalte der extrahierbaren Metalle in Leder
fest, die zunächst mit einer sauren Lösung aus künstlichem Schweiß extrahiert und anschließend mittels
optischer Emissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP-OES) oder mittels
Atomemissionsspektrometrie mit induktiv gekoppeltem Plasma (ICP-AES) oder mittels Massenspektrometrie
mit induktiv gekoppeltem Plasma (ICP-MS) oder mittels Atomabsorptionsspektrometrie (AAS) oder
Atomfluoreszenzspektrometrie (SFA) bestimmt werden.
Dieses Verfahren ist besonders zur Bestimmung von extrahierbarem Chrom in mit Chrom gegerbtem Leder
geeignet.
Das Verfahren bestimmt extrahierbare Metalle in Leder; es ist nicht spezifisch für die jeweilige chemische
Verbindung oder spezifisch für den Oxidationszustand der Metalle.
Das Verfahren ist zur Bestimmung vieler extrahierbarer Metalle anwendbar, zu denen die folgenden gehören:
Aluminium (Al) Kupfer (Cu) Nickel (Ni)
Antimon (Sb) Eisen (Fe) Kalium (K)
Arsen (As) Blei (Pb) Selen (Se)
Barium (Ba) Magnesium (Mg) Zinn (Sn)
Cadmium (Cd) Mangan (Mn) Titan (Ti)
Calcium (Ca) Quecksilber (Hg) Zink (Zn)
Chrom (Cr) Molybdän (Mo) Zirconium (Zr)
Kobalt (Co)
Die Bestimmungsgrenze von Blei liegt bei 3 mg/kg (siehe Anhang A).
Cuir - Détermination chimique de la teneur en métal - Partie 1: Métaux extractibles (ISO 17072-1:2011)
L'ISO 17012-1:2011 spécifie une méthode de détermination des métaux extractibles du cuir s'appuyant sur l'extraction à l'aide d'une solution de sueur artificielle acide suivie d'une détermination par spectrométrie d'émission optique avec plasma à couplage inductif (ICP-OES), ou par spectrométrie d'émission atomique avec plasma à couplage inductif (ICP-AES), ou par spectrométrie de masse avec plasma à couplage inductif (ICP-MS), ou par spectrométrie d'absorption atomique (AAS), ou par spectrométrie de fluorescence atomique (SFA).
La présente méthode est particulièrement adaptée à la détermination du chrome extractible dans les cuirs tannés au chrome.
La présente méthode détermine les métaux extractibles présents dans le cuir; elle n'est pas spécifique à un composé ou à l'état d'oxydation des métaux.
La méthode s'applique également à la détermination de nombreux métaux extractibles, dont: 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), étain (Sn), titane (Ti), zinc (Zn) et zirconium (Zr).
La limite de quantification du plomb extractible est de 3 mg/kg.
Usnje - Kemijsko določevanje kovin - 1. del: Izločljive kovine (ISO 17072-1:2011)
Ta standard določa metodo za določevanje izločljivih 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 usnju, barvanem s kromom.

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 17072-1 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 27-1.
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
