Leather - Chemical determination of formaldehyde content - Part 1: Method using high performance liquid chromatography (ISO 17226-1:2008)
ISO 17226-1:2008 specifies a method for the determination of free and released formaldehyde in leathers. This method is based on high performance liquid chromatography (HPLC). It is selective and not sensitive to coloured extracts.
The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extracted through hydrolysis contained in a water extract from the leather under standard conditions.
Leder - Chemische Bestimmung des Formaldehydgehalts - Teil 1: Hochleistungs-Flüssigkeitschromatographie (ISO 17226-1:2008)
Dieser Teil von ISO 17226 legt ein Verfahren zur Bestimmung von freiem und freigesetztem Formaldehyd in Leder fest. Dieses Verfahren beruht auf Hochleistungs-Flüssigkeitschromatographie (HPLC). Das Verfahren ist selektiv und gegen gefärbte Extrakte unempfindlich. Formaldehydgehalt ist die Menge an freiem Formaldehyd und durch Hydrolyse freigesetztem Formaldehyd, der in einem wässrigen Extrakt, der unter standardisierten Bedingungen erhalten wurde, enthalten ist.
Cuir - Dosage chimique du formaldéhyde - Partie 1: Méthode par chromatographie en phase liquide à haute performance (ISO 17226-1:2008)
L'ISO 17226-1:2008 spécifie une méthode permettant de doser le formaldéhyde libre et le formaldéhyde dégagé dans les cuirs. Cette méthode est fondée sur la chromatographie en phase liquide à haute performance (CLHP). Elle est sélective et insensible aux extraits colorés.
La teneur en formaldéhyde se définit par hypothèse comme la quantité de formaldéhyde libre et de formaldéhyde extrait de l'hydrolyse contenue dans un extrait d'eau provenant du cuir dans des conditions standard.

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 17226-1 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 Colorimetric Section of the method IUC 19 which was declared an official method at the IULTCS
Delegates meeting on 31st May 2003 in Cancún, Mexico.
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 sampling and the testing of leather. ISO recognizes IULTCS as an
international standardizing body for the preparation of test methods for leather.
This first edition of ISO 17226-1, together with ISO 17226-2, cancels and replaces ISO/TS 17226:2003, which
has been technically revised.
ISO 17226 consists of the following parts, under the general title Leather — Chemical determination of
formaldehyde content:
⎯ Part 1: Method using high performance liquid chromatography
⎯ Part 2: Method using colorimetric analysis
ISO 17226-1:2008(E)
INTERNATIONAL STANDARD
IULTCS/IUC 19-1:2008(E)
Leather — Chemical determination of formaldehyde content —
Part 1:
Method using high performance liquid chromatography
1 Scope
This part of ISO 17226 specifies a method for the determination of free and released formaldehyde in
leathers. This method is based on high performance liquid chromatography (HPLC). It is selective and not
sensitive to coloured extracts.
The formaldehyde content is taken to be the quantity of free-formaldehyde and formaldehyde extracted
through hydrolysis contained in a water extract from the leather under standard conditions.
2 Conformance
When compared with ISO 17226-2, the two analytical methods should give similar trends but not necessarily
the same absolute result. Therefore, in the case of dispute, this method (ISO 17226-1) shall be used in
preference to ISO 17226-2.
