18、dies). 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 an
19、d 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 de
20、scribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

25、ion 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 th
26、e sampling and testing of leather. ISO recognizes IULTCS as an international standardizing body for the preparation of test methods for leather.IULTCS/IUC 36:2017(E)iv ISO 2017 All rights reservedBS EN ISO 20137:2017ISO 20137:2017(E)IntroductionThis document was prepared in collaboration by IULTCS a
27、nd by CEN/TC 289 Leather in order to provide an overview of chemical test methods for the leather industry. This can be used by those involved in setting specifications for leather, especially for those parameters relating to restricted chemical substances.Regulations restrict the use of certain che
28、micals in consumer products. The leather industry has already taken actions by replacing the restricted substances or assuming the limits imposed by these restrictions. Many brand name manufacturers require certificates of compliance from their suppliers but too often these refer to analytical metho
29、ds from other industries that are not suitable for use in testing leather.Through the collaboration of IULTCS and CEN/TC 289, a considerable number of leather specific EN and ISO standard test methods have been developed for the chemical analysis of leather. The International Standards are tested by
30、 inter-laboratory studies, have been proven scientifically valid and are subjected to updating processes according to ISO protocols.Chemical analysis of leatherLeather is a complex substrate to chemically analyse. After tanning, leather typically undergoes wet-processing in aqueous media at low temp
31、eratures (60 C) and in an acid pH range of 3,5 to 5,5. The characteristic properties of leather are achieved by mostly using a range of anionic retanning agents (natural and/or synthetic), polymers and oils, as well as anionic dyes for achieving the required colour. In analytical procedures, when le
32、ather is extracted, some of these substances can be removed and make a complex matrix for the analysis. This should be considered when establishing quantification limits for leather analyses. Too often unrealistic limits established in aqueous solutions, e.g. waste water analysis, are quoted in spec
33、ifications for leather.This document gives an overview of those internationally accepted chemical test procedures established specifically for leather.IULTCS/IUC 36:2017(E) ISO 2017 All rights reserved vBS EN ISO 20137:2017BS EN ISO 20137:2017Leather Chemical tests Guidelines for testing critical ch

Those chemical substances that are not mentioned in this document do not need to be determined, thus avoiding unnecessary analytical costs.2 Normative referencesThe following documents are referred to in the text in such a w
