Leather — Tests for colour fastness — Colour fastness to crocking
This document specifies a method to determine the amount of colour transferred from the surface of coloured leather to other surfaces by rubbing. 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.
Cuir — Essais de solidité des coloris — Solidité des coloris au dégorgement par frottement
Le présent document spécifie une méthode pour déterminer la quantité de couleur transférée de la surface d’un cuir coloré à d’autres surfaces, par frottement. 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.

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.

Avant-propos
L'ISO (Organisation internationale de normalisation) est une fédération mondiale d'organismes nationaux
de normalisation (comités membres de l'ISO). L'élaboration des Normes internationales est en général
confiée aux comités techniques de l'ISO. Chaque comité membre intéressé par une étude a le droit de faire
partie du comité technique créé à cet effet. Les organisations internationales, gouvernementales et non
gouvernementales, en liaison avec l'ISO, participent également aux travaux. L'ISO collabore étroitement avec
la Commission électrotechnique internationale (IEC) en ce qui concerne la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
décrites dans les Directives ISO/IEC, Partie 1. Il convient, en particulier, de prendre note des différents
