Leather - Determination of total content of certain bisphenols (ISO 11936:2023)
SIST EN ISO 11936:2023

This document specifies a method for determining the total content (solvent extractible) of the following bisphenols in leather:
—     bisphenol A;
—     bisphenol B;
—     bisphenol F;
—     bisphenol S.
This method requires the use of liquid chromatography (LC) with either a single quadrupole mass spectrometer (MS), a triple quadrupole mass spectrometer (MS/MS), an ultraviolet (UV) detector, a diode array detector (DAD) or a fluorescence detector (FLD) to identify and quantify the bisphenols.
NOTE            This method can also be used for other bisphenols if they are validated by the laboratory.

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.

Leather - Test for adhesion of finish (ISO 11644:2022)
SIST EN ISO 11644:2023

This document specifies a method for measuring the adhesion of the finish to leather or the adhesion between two adjacent layers of the finish.
The method is valid for all finished flexible leathers with a smooth surface that can be bonded to an adherent plate without the adhesive penetrating into the finish. Preliminary experiments can be necessary to determine whether these conditions are met.
This test method applies to finished leathers with a thick finish-coat.
The method specified in this document does not apply to unpigmented articles or articles without a continuous coating layer, such as:
—    nubuk;
—    aniline;
—    pull-up;
—    suede;
—    perforated leather.
