Leather - Tests for colour fastness - Colour fastness to water (ISO 11642:1993)

The principle of the method specified is soaking a leather specimen and also a piece of adjacent fabric, laid against each side to be tested, in demineralized water, leaving the composite specimen under pressure for a specified time in a suitable apparatus, drying the leather specimen and adjacent fabric, and assessing the change in colour of the specimen and the staining of the adjacent fabric with the grey scales. Leathers with a finish may be tested intact or with the finish broken. The method is applicable to leather of all kinds at all stages of processing.

Leder - Farbechtheitsprüfungen - Farbechtheit gegen Wasser (ISO 11642:1993)

Diese Internationale Norm legt ein Verfahren fest zur Bestimmung der Farbechtheit aller Arten von Leder in allen Verarbeitungsstufen gegen Wasser. Anmerkung 1: Während der Prüfung kann sich das anliegende Gewebe verfärben und die Farbe des Leders kann sich verändern.

Cuir - Essais de solidité des teintures - Solidité des teintures a l'eau (ISO 11642:1993)

La présente Norme internationale spécifie une méthode permettant de déterminer la solidité à l'eau des teintures du cuir de toutes catégories à toutes les phases du traitement.NOTE 1 Au cours de l'essai, le tissu témoin peut présenter des taches de dégorgement et la couleur du cuir risque de changer.

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. Esch member body interested in a subject for
which a technical committee has been established has the right to be re-
presented 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.
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.
International Standard ISO 11642 was prepared by the Fastness Tests
Commission of the International Union of Leather Technologists and
Chemists Societies (IUF Commission, IULTCS). lt is based on IUF 421
published in J. Sec. Leather Tech. Chem., 71, pp. 22-24 (1987), and de-
clared an official method of the IULTCS in October 1989.
Annexes A and B of this International Standard are for information only.
