Leather - Determination of total content of certain bisphenols (ISO/DIS 11936:2022)

This document is a method for determining the total content (solvent extractible) of the following bisphenols:
—   Bisphenol A
—   Bisphenol B
—   Bisphenol F
—   Bisphenol S
This method requires the use of liquid chromatography (LC) with triple quadrupole mass spectrometer (MSMS) or with Diode Araay Detector (DAD) or FLD to identify and quantify the bisphenols.

Leder - Bestimmung des Gesamtgehalts von einzelnen Bisphenolen (ISO/DIS 11936:2022)

Dieses Dokument legt ein Verfahren zur Bestimmung des Gesamtgehalts (lösemittelextrahierbar) der folgenden Bisphenole in Leder fest:
   Bisphenol A;
   Bisphenol B;
   Bisphenol F;
   Bisphenol S.
Dieses Verfahren erfordert den Einsatz von Flüssigchromatographie (LC) entweder mit einem Single-Quadrupol-Massenspektrometer (MS), einem Triple-Quadrupol-Massenspektrometer (MS/MS), einem Ultraviolett (UV)-Detektor, einem Diodenarray-Detektor (DAD) oder einem Fluoreszenz-Detektor (FLD) zur Identifizierung und Quantifizierung der Bisphenole.
ANMERKUNG   Dieses Verfahren kann auch für andere Bisphenole verwendet werden, wenn sie vom Labor validiert wurden.

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.

assessment, as well as information about ISO's adherence to the WTO principles in the Technical

Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information

ISO 11936 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.
