Leather - Tests for colour fastness - Colour fastness to perspiration (ISO 11641:1993)

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 artificial perspiration solution, 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 - Farbechtheitspru*fungen - Farbechtheit gegen Schweiß (ISO 11641:2002)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Farbechtheit aller Arten von Leder in allen Verarbeitungsstufen gegenüber Schweiß fest, hauptsächlich findet sie jedoch bei Handschuh-, Bekleidungs- und Futterleder sowie Leder als Obermaterial von ungefüttertem Schuhwerk Anwendung.
ANMERKUNG 1   Während der Prüfung kann das Begleitgewebe anbluten und die Farbe des Leders kann sich verändern.
Zur Simulation der Wirkung von menschlichem Schweiß wird bei dem Verfahren eine künstliche Schweißlö-sung verwendet. Weil sich der Schweiß von Individuum zu Individuum unterscheidet, ist es nicht möglich, ein Verfahren von allgemeiner Gültigkeit zu entwickeln, die nachfolgend festgelegte künstliche alkalische Schweißlösung führt jedoch zu Ergebnissen, die in den meisten Fällen den Ergebnissen mit natürlichem Schweiß entsprechen.
ANMERKUNG 2   Im Allgemeinen ist frisch produzierter menschlicher Schweiß schwach sauer. Mikroorganismen verursachen dann eine Veränderung, der pH-Wert wird gewöhnlich schwach basisch (pH-Wert 7,5 bis 8,5). Alkalischer Schweiß hat eine wesentlich größere Auswirkung auf die Farbe des Leders als saurer Schweiß. Demzufolge wird eher eine alkalische Schweißlösung als eine saure verwendet, um die in der Praxis anzutreffenden schärfsten Bedingungen zu simulieren.

Cuir - Essai de solidité des teintures - Solidité des teintures à la sueur (ISO 11641:1993)

L'ISO 11641:1993 spécifie une méthode permettant de déterminer la solidité des teintures à la sueur sur les cuirs de toutes catégories, à toutes les phases du traitement, mais elle s'applique particulièrement aux cuirs destinés à la fabrication des gants, des vêtements et des parements, ainsi qu'aux cuirs pour les tiges de chaussures sans doublure.
La méthode utilise une solution artificielle de sueur afin de simuler l'action de la transpiration humaine. Attendu que la sueur varie largement d'une personne à une autre, il n'est pas possible de concevoir une méthode ayant une validité universelle, mais la sueur artificielle alcaline (pH compris entre 7,5 et 8,5) spécifiée dans l'ISO 11641:1993 donne des résultats correspondants dans la plupart des cas à ceux obtenus avec la sueur naturelle.
