Leather - Chemical determination of metal content - Part 1: Extractable metals (ISO 17072-1:2019)

This document 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), inductively coupled plasma mass spectrometry (ICP-MS), atomic absorption spectrometry (AAS) or spectrometry of atomic fluorescence (SFA).
This method determines extractable metals in leather; it is not compound-specific or specific to the oxidation state of the metals. This method is especially suitable for determining the extractable chromium in chromium-tanned leathers.

Leder - Chemische Bestimmung des Metallgehaltes - Teil 1: Extrahierbare Metalle (ISO 17072-1:2019)

Dieses Dokument 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 (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) bestimmt werden.
Dieses Verfahren bestimmt extrahierbare Metalle in Leder; es ist nicht spezifisch für die jeweilige chemische Verbindung oder spezifisch für den Oxidationszustand der Metalle. Dieses Verfahren ist besonders zur Bestimmung von extrahierbarem Chrom in mit Chrom gegerbtem Leder geeignet.
Das Verfahren ist zur Bestimmung vieler extrahierbarer Metalle anwendbar, zu denen die folgenden gehören:

Cuir - Détermination chimique de la teneur en métal - Partie 1: Métaux extractibles (ISO 17072-1:2019)

Le présent document 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), par spectrométrie de masse avec plasma à couplage inductif (ICP-MS), par spectrométrie d'absorption atomique (AAS) ou par spectrométrie de fluorescence atomique (SFA).
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 présente méthode est particulièrement adaptée à la détermination du chrome extractible dans les cuirs tannés au chrome.

Usnje - Kemijsko določevanje kovin - 1. del: Izločljive kovine (ISO 17072-1:2019)

Ta dokument določa metodo za določevanje izločljivih kovin v usnju z izločanjem z umetno kislinsko znojno raztopino in naknadnim določevanjem z optično emisijsko spektrometrijo z induktivno sklopljeno plazmo (ICP-OES), masno spektrometrijo z induktivno sklopljeno plazmo (ICPMS),
atomsko absorpcijsko spektrometrijo (AAS) ali atomsko fluorescenčno spektrometrijo (SFA).
Ta metoda določa izločljive kovine v usnju, pri čemer ne obravnava določene spojine ali določenega
oksidacijskega stanja kovin. Ta metoda je posebej primerna za določevanje izločljivega
kroma v usnju, ustrojenem 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.

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

URL: www .iso .org/iso/foreword .html.

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 17072-1:2011), which has been technically

revised as follows:
— the Scope and Clauses 5, 6, 7, 8.3, 9 and 10 have been editorially modified;

— 7.2 and 8.2 have been technically modified. 7.2 refers to ISO 4044 for sample preparation, which

requires the user to grind sufficiently large pieces of leather or cut small pieces of leather;

— the previous subclauses 6.3 and 7.3 from ISO 17072-1:2011 have been deleted.
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.
