Leather - Tests for colour fastness - Colour fastness to crocking (ISO 20433:2012)
This International Standard specifies a method for determining the amount of colour transferred from the surface of coloured leather to other surfaces by rubbing with a white cotton cloth.
Two tests are carried out, one with a dry rubbing cloth and one with a wet rubbing cloth.
The method is applicable to all types of coloured leather. Since after treatments of the leather as well as surface finishes can affect the degree of colour transfer, the test can be made before and/or after such treatments.
Leder - Farbechtheitsprüfungen - Farbechtheit gegen Reiben (ISO 20433:2012)
Diese Internationale Norm legt ein Prüfverfahren zur Bestimmung der Farbmenge fest, die von der Oberfläche von farbigem Leder auf andere Oberflächen durch Reiben mit einem weißen Baumwollgewebe übertragen wird.
Zwei Prüfungen werden durchgeführt, eine mit einem trockenen und eine mit einem nassen Reibgewebe.
Das Verfahren gilt für alle Typen von farbigem Leder. Da sowohl Nachbehandlungen von Leder als auch Zurichtungen der Oberfläche den Grad der Farbübertragung beeinflussen können, kann die Prüfung vor und/oder nach diesen Behandlungen durchgeführt werden.
Cuir - Essais de solidité des coloris - Solidité des coloris au dégorgement par frottement (ISO 20433:2012)
La présente Norme internationale spécifie une méthode permettant de déterminer la quantité de couleur transférée de la surface d'un cuir coloré à d'autres surfaces, par frottement au moyen d'une étoffe en coton blanc.
Deux essais sont réalisés: l'un avec une étoffe de frottement à sec et l'autre avec une étoffe de frottement humide.
Cette méthode s'applique à tous les types de cuir coloré. Étant donné que les post-traitements du cuir ainsi que les apprêts peuvent avoir une incidence sur le transfert de la couleur, l'essai peut être effectué avant et/ou après ces traitements.
Usnje - Preskušanje obstojnosti barve - Obstojnost barve proti drgnjenju (ISO 20433:2012)
Ta mednarodni standard določa metodo za določevanje količine barve, ki se prenese s površine barvnega usnja na druge površine pri drgnjenju z belo bombažno krpo. Izvedeta se dva preskusa: eden s suho krpo za drgnjenje in eden z mokro krpo za drgnjenje. Ta metoda se uporablja se za vse vrste barvnega usnja. Ker lahko naknadna in površinska obdelava usnja vpliva na stopnjo prenosa barve, se lahko preskus izvede pred in/ali po takšnem postopku.

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.
