Leather - Tests for colour fastness - Colour fastness to perspiration (ISO 11641:2012)

Leather - Tests for colour fastness - Colour fastness to perspiration (ISO 11641:2012)

ISO 11641:2012 specifies a method for determining the colour fastness to perspiration of leather of all kinds at all stages of processing. It applies particularly to gloving, clothing and lining leathers, as well as leather for the uppers of unlined shoes.
The method uses an artificial perspiration solution to simulate the action of human perspiration. Since perspiration varies widely from one individual to the next, it is not possible to design a method with universal validity, but the alkaline artificial perspiration solution specified in ISO 11641:2012 will give results corresponding to those with natural perspiration in most cases.

Leder - Farbechtheitsprüfungen - Farbechtheit gegen Schweiß (ISO 11641:2012)

Diese Internationale Norm legt ein Verfahren zur Bestimmung der Farbechtheit aller Arten von Leder in allen Verarbeitungsstufen gegenüber Schweiß fest. Hauptsächlich findet sie bei Handschuh , Bekleidungs- und Futterleder sowie Leder als Obermaterial von ungefüttertem Schuhwerk Anwendung.
Zur Simulation der Wirkung von menschlichem Schweiß wird bei dem Verfahren eine künstliche Schweißlösung verwendet. Weil sich der Schweiß von Individuum zu Individuum unterscheidet, ist es nicht möglich, ein Verfahren von allgemeiner Gültigkeit zu entwickeln, die in dieser Internationalen Norm festgelegte künstliche alkalische Schweißlösung führt jedoch zu Ergebnissen, die in den meisten Fällen den Ergebnissen mit natürlichem Schweiß entsprechen.
ANMERKUNG   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 für farbiges Leder eine alkalische Schweißlösung verwendet, um die in der Praxis anzutreffenden schärfsten Bedingungen zu simulieren.

Cuir - Essais de solidité des coloris - Solidité des coloris à la sueur (ISO 11641:2012)

L'ISO 11641:2012 spécifie une méthode permettant de déterminer la solidité des coloris à la sueur sur les cuirs de toutes catégories, à toutes les phases du traitement. 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 de sueur artificielle 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 spécifiée dans l'ISO 11641:2012 donne des résultats correspondant dans la plupart des cas à ceux obtenus avec la sueur naturelle.

Usnje - Preskušanje obstojnosti barve - Obstojnost barve proti znoju (ISO 11641:2012)

Ta mednarodni standard določa metodo za določevanje obstojnosti barve proti znoju za usnje vseh vrst in pri vseh stopnjah obdelave. Uporablja se predvsem za usnjene rokavice, oblačila in podloge ter usnje za zgornji del nepodloženih čevljev. Metoda uporablja postopek umetnega znojenja, ki simulira znojenje človeka. Ker se intenzivnost znojenja posameznikov razlikuje, ni mogoče zasnovati metode z univerzalno veljavnostjo, vendar alkalna raztopina za umetno znojenje, podana v tem mednarodnem standardu, daje rezultate, ki v večini primerov ustrezajo rezultatom, pridobljenim z naravnim znojenjem.

Leather - Per- and polyfluoroalkyl substances - Part 1: Determination of non-volatile compounds by extraction method using liquid chromatography (ISO 23702-1:2023)
SIST EN ISO 23702-1:2023

This document specifies a test method for detection and quantification of extractable non-volatile per- and polyfluoroalkyl substances (PFAS) in leather and coated leather by solvent extraction and liquid chromatography coupled with mass spectrometry.
This document, taking into account the three-dimensional distribution of the fibres within leather, makes the evaluation of the PFAS with respect to the mass.
PFAS substances categories and applications are listed in Annex A, Table A.1. Classes of PFAS regulated compounds listed in Annex B, Table B.1, include acids, telomers, sulfonates and sulphonamide alcohols. Classes of other non-regulated compounds that can be determined by this document are listed in Annex C, Table C.1.
NOTE 1        By applying the method specified in this document, the concentration of free fluorotelomer alcohols (FTOH) in a sample cannot be correctly quantified if perfluoropolymers that release FTOH due to transesterification with the extraction solvent methanol are present in the sample.
NOTE 2        Some regulations (e.g. Reference [4]) also restrict perfluoropolymers having a linear or branched perfluoroheptyl group with the moiety (C7F15)C as one of the structural elements that can degrade to PFOA, e.g. polymers containing 2-perfluorooctylethanol (8:2 FTOH, CAS Registry Number® 678-39-7) bonded as esters. To determine whether these perfluoropolymers are intentionally present, it could be necessary to introduce an alkaline hydrolysis method to remove the 8:2 FTOH side-chain from the polymer. In addition, other FTOH, e.g. 6:2 FTOH or 10:2 FTOH, will be released from relevant perfluoropolymers by alkaline hydrolysis.

Leather - Determination of ethoxylated alkylphenols (APEO) - Part 1: Direct method (ISO 18218-1:2023)
SIST EN ISO 18218-1:2023

This document is a method for determining ethoxylated alkylphenols (APEO) [nonyphenol ethoxylate (NPEOn, where 2 ≤ n ≤ 16) and octylphenol ethoxylate (OPEOn, where 2 ≤ n ≤ 16)] in leather. This direct method is especially suitable when a larger number of leather samples are to be checked for the presence of ethoxylated alkylphenols.
This method requires the use of liquid chromatography (LC) with a triple quadrupole mass spectrometer (MS/MS) to identify and quantify the ethoxylated alkylphenols.
NOTE 1        In the leather industry, the most commonly used ethoxylated alkylphenol is the NPEO, with an average of 9 EO. It has an optimum cloud point in water for the typical leather processing temperatures of 40 °C to 55 °C.
NOTE 2        This document and ISO 18218-2 use different solvents for the extraction of the ethoxylated alkylphenols from leather. Consequently, the two analytical methods are expected to give similar trends but not necessarily the same absolute result for the ethoxylated alkylphenol content in leather.

Leather - Tests for colour fastness - General principles of testing (ISO 7906:2022)
SIST EN ISO 7906:2023

This document specifies general principles on colour fastness evaluation tests for leather, as listed in Annex A.
Procedures included in this document are common to most of the fastness test methods.
This document provides a common basis for testing and reporting colour fastness. The uses and limitations of the methods are pointed out, several terms are defined, an outline of the drafting of the methods is given and the contents of the clauses describing the methods are discussed.
Procedures common to a number of the methods are discussed briefly.
Colour fastness means the resistance of the colour to the different agents to which these materials can be exposed during manufacture and their subsequent use.
The change in colour of leather and staining of undyed adjacent fabrics or other materials are assessed as fastness ratings.
Other visible changes in the leather under test, for example surface appearance, change in gloss or shrinkage, are considered as separate properties and reported as such.
The leather fastness test methods can be used not only for assessing leather and related materials, such as coated leather and leather board, but also for the eventual assessment of the colour fastness of leather dyes. When such a method is so used, the dye is applied to a specified retanned leather or crust leather in defined depths of colour by stated procedures and the material is then tested in the usual way.
