(Main)Leather - Chemical determination of metal content - Part 2: Total metal content (ISO 17072-2:2019)
Leather - Chemical determination of metal content - Part 2: Total metal content (ISO 17072-2:2019)
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.
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) Nickel (Ni) Zirconium (Zr)
This method is also suitable for determining Boron (B) in leather.
In the case of chromium-tanned leathers, it is often more relevant to use ISO 5398-1[1], ISO 5398-2[2],
ISO 5398-3[3] or ISO 5398-4 [4].
Interlaboratory test results and the quantification limits possible with ICP-OES are given in Table A.1
and Table A.2 of Annex A.
Leder - Chemische Bestimmung des Metallgehaltes - Teil 2: Gesamtmetallgehalt (ISO 17072-2:2019)
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¬spektro-metrie mit induktiv gekoppeltem Plasma (en: inductively coupled plasma optical emission spectrometry, ICP OES), Massenspektrometrie mit induktiv gekoppeltem Plasma (en: inductively coupled plasma mass spectrometry, ICP MS), Atomabsorptionsspektrometrie (en: atomic absorption spectrometry, AAS) oder Atomfluoreszenzspektrometrie (en: spectrometry of atomic fluorescence, SFA) 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:
Cuir - Détermination chimique de la teneur en métal - Partie 2: Teneur totale en métaux (ISO 17072-2:2019)
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 d'absorption atomique (AAS), 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.
Usnje - Kemijsko določevanje kovin - 2. del: Celotni delež kovin (ISO 17072-2:2019)
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 celoten delež kovin v usnju, pri čemer 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 ustrezneje uporabiti standard ISO 5398-1[1], ISO 5398-2[2],
ISO 5398-3[3] ali ISO 5398-4 [4].
Rezultati medlaboratorijskih preskusov in omejitve kvantifikacije, ki so mogoče pri optični emisijski spektrometriji z induktivno sklopljeno plazmo, so podani v preglednici A.1
ter preglednici A.2 dodatka A.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by the Chemical Test Commission of the International Union of Leather
Technologists and Chemists Societies (IUC Commission, IULTCS) in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 289, Leather, the secretariat of
which is held by UNI, in accordance with the agreement on technical cooperation between ISO and CEN
(Vienna Agreement).
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.
This second edition cancels and replaces the first edition (ISO 17072-2:2011), which has been technically
revised as follows:
— the Scope and Clauses 4, 5, 6, 7, 8, and 10 have been editorially and technically modified;
— 7.2 now refers to ISO 4044 for sample preparation, which requires the user to grind sufficiently
large pieces of leather or cut small pieces of leather;
— 8.1, referring to the acid digestion, has been technically revised;
— 6.4 from ISO 17072-2:2011 has been included in 8.1 of this edition.
A list of all parts in the ISO 17072 series can be found on the ISO website.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/members .html.
