Leather - Tests for colour fastness - Colour fastness to saliva (ISO 20701:2024)
ISO 20701 | IUF 427:2017 specifies a method for determining the colour fastness to saliva of all kinds of leathers, independent of the colouring procedure applied.
The method uses an artificial saliva solution to simulate whether colouring materials can migrate from leather to the mouth or to the mucous membranes.
Leder - Prüfung der Farbechtheit - Farbechtheit gegenüber Speichel (ISO 20701:2024)
Dieses Dokument legt ein Verfahren zur Bestimmung der Farbechtheit gegen Speichel bei allen Lederarten unabhängig vom Färbevorgang fest.
Das Verfahren nutzt eine künstliche Speichellösung, um zu simulieren, ob Farbstoffe vom Leder zum Mund oder zu den Schleimhäuten migrieren können.
Cuir - Essais de solidité des coloris - Solidité des coloris à la salive (ISO 20701:2024)
ISO 20701 | IUF 427:2017 spécifie une méthode permettant de déterminer la solidité des coloris à la salive, destinée à tous les types de cuirs, quelle que soit la technique de teinture utilisée.
Cette méthode consiste à utiliser une solution de salive artificielle afin de déterminer si les matières colorantes peuvent migrer du cuir vers la bouche ou les muqueuses.
Usnje - Preskušanje barvne obstojnosti - Barvna obstojnost na slino (ISO 20701:2024)
Standard ISO 20701 | IUF 427:2017 določa metodo za ugotavljanje barvne obstojnosti na slino za usnje vseh vrst, neodvisno od uporabljenega postopka obarvanja.
Metoda uporablja raztopino umetne sline za simulacijo, s katero se ugotavlja, ali se lahko barvni materiali prenesejo iz usnja v usta ali sluznico.

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 document 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).
