Textiles and textile products - Organic fluorine - Part 2: Determination of volatile compounds by extraction method using gas chromatography

This document specifies a test method (using gas chromatography, GC) for detection and quantification of selected extractable perfluorinated and polyfluorinated substances in textile materials (fibres, yarns, fabrics) and coated fabrics.
NOTE 1 CEN/TR 16741 defines which materials are applicable to this determination.
A test method (using liquid chromatography, LC) for detection and quantification of selected extractable perfluorinated and polyfluorinated substances is specified in EN 17681-1.
NOTE 2 Both this document and EN 17681-1 are needed for PFOA related substances.
Classes of regulated compounds are listed in Table 2. Classes of other non-regulated compounds that can be determined by this document are defined in Annex C, Table C.1. This document is also applicable for further PFAS substances provided that the method is validated with the additional compounds.
NOTE 3 Commission Delegated Regulation (EU) 2020/784 amending Annex I to the POP Regulation (EU) 2019/1021 as regards the listing of perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds defines among other that “’…PFOA-related compounds’ means the following: … any substances that degrade to PFOA, including any substances (including salts and polymers) having a linear or branched perfluoroheptyl group with the moiety (C7F15)C as one of the structural elements.” To determine whether these are intentionally present it could be necessary to introduce an alkaline hydrolysis method to remove the side-chain from the polymer. According to Commission Regulation (EU) 2021/1297 [7], this applies similarly to C9-C14 PFCAs-related compounds. A future revision of this document will address this aspect.

Textilien und textile Erzeugnisse - Organisches Fluor - Teil 2: Bestimmung des Gehaltes an flüchtigen Verbindungen durch Extraktionsverfahren mittels Gaschromatographie

Dieses Dokument legt ein Prüfverfahren (unter Anwendung von Gaschromatographie, GC (en: gas chromatography)) zum Nachweis und zur quantitativen Bestimmung von ausgewählten extrahierbaren perfluorierten und polyfluorierten Verbindungen in textilen Materialien (Fasern, Garne, textile Flächengebilde) und beschichteten textilen Flächengebilden fest.
ANMERKUNG 1 CEN/TR 16741 legt fest, welche Materialien für diese Bestimmung anzuwenden sind.
Ein Prüfverfahren (unter Anwendung von Flüssigkeitschromatographie, LC (en: liquid chromatography)) zum Nachweis und zur quantitativen Bestimmung von ausgewählten extrahierbaren perfluorierten und polyfluorierten Verbindungen ist in EN 17681-1 festgelegt.
ANMERKUNG 2 Sowohl dieses Dokument als auch EN 17681-1 werden für PFOA verwandte Verbindungen benötigt.
Die Klassen regulierter Verbindungen sind in Tabelle 2 aufgeführt. Klassen anderer, nichtregulierter Verbindungen, die nach diesem Dokument bestimmt werden können, sind in Anhang C, Tabelle C.1, festgelegt. Dieses Dokument ist auch anzuwenden für weitere PFAS Verbindungen, vorausgesetzt, dass das Verfahren mit den zusätzlichen Verbindungen validiert wird.
ANMERKUNG 3 Die delegierte Verordnung (EU) 2020/784 der Kommission zur Änderung des Anhangs I der Verordnung (EU) 2019/1021 des Europäischen Parlaments und des Rates hinsichtlich der Aufnahme von Perfluoroctansäure (PFOA), ihrer Salze und von PFOA verwandten Verbindungen legt u. a. fest, dass „PFOA verwandte Verbindungen umfasst: ...alle Stoffe (...), die zu PFOA abgebaut werden, einschließlich aller Stoffe (auch Salze und Polymere), die eine lineare oder verzweigte Perfluorheptylgruppe mit dem Bestandteil (C7F15)C als Strukturelement aufweisen.“ Um festzustellen, ob ihre Anwesenheit beabsichtigt ist, könnte die Aufnahme eines alkalischen Hydrolyseverfahrens zur Entfernung der Seitenkette des Polymers erforderlich sein. Nach Verordnung (EU) 2021/1297 der Kommission [7] trifft dies gleichermaßen auf C9-C14 PFCA-verwandte Stoffe zu. Eine zukünftige Überarbeitung dieses Dokumentes wird diesen Gesichtspunkt berücksichtigen.

Textiles et produits textiles - Fluor organique - Partie 2 : Détermination de composés volatils par une méthode d’extraction utilisant la chromatographie en phase gazeuse

Le présent document spécifie une méthode d'essai (par chromatographie en phase gazeuse, GC) pour la détection et la quantification, dans des matières textiles (fibres, fils, étoffes) et des supports textiles revêtus, de substances perfluorées et polyfluorées extractibles sélectionnées.
NOTE 1 Le CEN/TR 16741 définit les matériaux auxquels s'applique cette détermination.
Une méthode d'essai (par chromatographie en phase liquide, LC) pour la détection et la quantification de substances perfluorées et polyfluorées extractibles sélectionnées est spécifiée dans l'EN 17681-1.
NOTE 2 Le présent document et l'EN 17681-1 sont tous les deux nécessaires pour les substances apparentées au PFOA.
Les classes de composés réglementés sont répertoriées dans le Tableau 2. Les classes d'autres composés, non réglementés, qui peuvent être déterminés en appliquant le présent document sont définies dans le Tableau C.1 (Annexe C). Le présent document est également applicable à d'autres PFAS, à condition que la méthode soit validée avec les composés additionnels.
NOTE 3 Le règlement délégué (UE) 2020/784 de la Commission modifiant l'annexe I du règlement (UE) 2019/1021 concernant les polluants organiques persistants aux fins d’y inscrire l’acide perfluorooctanoïque (PFOA), ses sels et les composés apparentés au PFOA stipule, entre autres, ce qui suit : « par " composés apparentés au PFOA ", il est entendu : … toutes les substances qui se dégradent en PFOA, y compris les substances (sels et polymères compris) qui comportent, parmi leurs éléments structurels, un groupe fonctionnel perfluoroheptyle (C7F15)C linéaire ou ramifié. » Pour déterminer si leur présence est intentionnelle, il pourrait s'avérer nécessaire d'introduire une méthode d'hydrolyse alcaline pour supprimer la chaîne latérale du polymère. Conformément au règlement (UE) 2021/1297[7] de la Commission, ceci s'applique de manière similaire aux composés apparentés aux PFCA en C9-C14. Le sujet sera abordé dans une future révision du présent document.

Overview

EN 17681-2:2022 - Textiles and textile products - Part 2: Determination of volatile organic fluorine compounds by extraction using gas chromatography - is a CEN standard that specifies a laboratory test method for detecting and quantifying selected extractable per‑ and polyfluoroalkyl substances (PFAS) in textile materials (fibres, yarns, fabrics) and coated fabrics. The method uses solvent extraction followed by analysis by gas chromatography (GC), typically with mass spectrometric detection (GC‑MS/MS, GC‑MS/PCI, GC‑MS/EI). The standard supports regulatory compliance related to PFOA, PFOS and related compounds and can be extended to additional PFAS after method validation.

Key topics and technical requirements

• Scope and applicability: Applies to volatile/extractable PFAS in textiles and coated materials; CEN/TR 16741 clarifies applicable materials.
• Principle: Solvent extraction of test specimen and instrumental analysis by GC with appropriate detectors and ion selection.
• Sampling and specimen preparation: Includes area‑based and mass‑based sampling rules and instructions for preparing test specimens.
• Reagents and equipment: Defines required solvents, internal standards and GC instrumentation options (GC‑MS/MS, GC‑MS with PCI or EI) and typical chromatographic conditions (Annex D).
• Analytical procedure: Preparation of stock and calibration solutions, internal standardization, extraction protocol and GC analysis (Sections 8.1–8.5).
• Quantification and quality criteria: Calibration, calculation of results, summation of PFAS groups, and determination of Limit of Detection (LoD) and Limit of Quantification (LoQ). Method reliability and reporting requirements are specified.
• Annexes:
  • Annex A: usable ions and LOQ guidance for GC methods.
  • Annex B: potential GC interferences.
  • Annex C: list of non‑regulated PFAS that can be analyzed.
  • Annex D: example chromatographic conditions.
• Regulatory context: Aligns with POP Regulation (EU) 2019/1021 and delegated/amending regulations addressing PFOA-related compounds and C9–C14 PFCAs. Note on possible need for alkaline hydrolysis for certain polymeric precursors (future revision to address).

Practical applications and users

• Compliance testing labs verifying textiles against EU POP and REACH/PFAS restrictions.
• Manufacturers and finishers performing incoming/outgoing quality control for oil/ water‑repellent finishes.
• Brand owners and retailers assessing supplier compliance and product safety.
• Environmental and forensic laboratories investigating PFAS contamination in fabrics and coated articles.
• Regulators and accreditation bodies setting test criteria and enforcement evidence.

Introduction
In the European Union, according to Regulation (EU) 2019/1021 on persistent organic pollutants (POP),
Article 3, Clause 1, in connection with Annex I amended by Commission Delegated Regulation
(EU) 2020/784, the manufacturing, placing on the market and use of perfluorooctanoic acid (PFOA), its
salts and PFOA-related compounds, whether on their own, in mixtures or in articles, is prohibited. This
is in addition to the existing prohibition of perfluorooctane sulfonic acid and its derivatives (PFOS).
According to Article 4 Clause 1. (b) this does not apply in the case of a substance present as an
unintentional trace contaminant, as specified in the relevant entries of Annex I in substances, mixtures
or articles.
Annex I Part A, describing perfluorooctane sulfonic acid and its derivatives (PFOS), contains the specific
exemption (Point 2) to concentrations of PFOS in semi-finished products or articles, or parts thereof, if
the concentration of PFOS is lower than 0,1 % mass fraction calculated with reference to the mass of
structurally or micro-structurally distinct parts that contain PFOS or, for textiles or other coated
materials, if the amount of PFOS is lower than 1 μg/m of the coated material. PFOS compounds have the
+
formula C F SO X where X = OH, Metal salt (O-M ), halide, amide and other derivatives, including
8 17 2
polymers.
In Annex I Part A, describing perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds,
contains the specific exemption (Point 1) to concentrations of PFOA or any of its salts equal to or below
0,025 mg/kg (0,000 002 5 % mass fraction) where they are present in substances, mixtures or articles.
In addition, (Point 2) Article 4(1) applies to concentrations of any individual PFOA-related compound or
a combination of PFOA-related compounds equal to or below 1 mg/kg (0,000 1 % mass fraction) where
they are present in substances, mixtures or articles.
PFOA, its salts and PFOA-related compounds means the following:
i) perfluorooctanoic acid, including any of its branched isomers;
ii) its salts;
iii) PFOA-related compounds which, for the purposes of the Convention, are any substances that degrade
to PFOA, including any substances (including salts and polymers) having a linear or branched
perfluoroheptyl group with the moiety (C F )C as one of the structural elements.
7 15
The following compounds are not included as PFOA-related compounds:
iv) C F -X, where X = F, Cl, Br;
8 17
v) fluoropolymers that are covered by CF [CF ] -R’, where R’ = any group, n > 16;
3 2 n
vi) perfluoroalkyl carboxylic acids (including their salts, esters, halides and anhydrides) with ≥ 8
perfluorinated carbons;
vii) perfluoroalkane sulfonic acids and perfluoro phosphonic acids (including their salts, esters, halides
and anhydrides) with ≥ 9 perfluorinated carbons;
viii) perfluorooctane sulfonic acid and its derivatives (PFOS), as listed in Annex I.
As a further exemption in Annex I Part A (Point 5 c) the manufacturing, placing on the market and use of
PFOA, its salts and PFOA-related compounds is allowed in textiles for oil and water repellency for the
protection of workers from dangerous liquids that comprise risks to their health and safety, until 4 July
2023.
Commission Regulation (EU) 2021/1297 amending Regulation (EC) No 1907/2006 (REACH), Annex
XVII [7] restricts perfluorocarboxylic acids containing 9 to 14 carbon atoms in the chain (C9-C14 PFCAs),
their salts and C9-C14 PFCA-related substances from 25 February 2023.
This restriction concerns the following substances:
Linear and branched perfluorocarboxylic acids of the formula C F -C(= O)OH where n = 8, 9, 10, 11,
n 2n+1
12, or 13 (C9-C14 PFCAs), including their salts, and any combinations thereof;
Any C9-C14 PFCA-related substance having a perfluoro group with the formula C F - directly attached
n 2n+1
to another carbon atom, where n = 8, 9, 10, 11, 12, or 13, including their salts and any combinations
thereof;
Any C9-C14 PFCA-related substance having a perfluoro group with the formula C F - that it is not
n 2n+1
directly attached to another carbon atom, where n = 9, 10, 11, 12, 13 or 14 as one of the structural
elements, including their salts and any combinations thereof.
The following substances are excluded from this designation:
C F -X, where X = F, Cl, or Br
n 2n+1
where n = 9, 10, 11, 12, 13 or 14, including any combinations thereof,
C F -C(= O)OX' where n > 13 and X' = any group, including salts.
n 2n+1
Several per- and poly-fluorinated alkylated substances (PFAS), which are not restricted under the POP
Regulation have been added as Substances of Very High Concern (SVHC) to the Candidate List according
to Regulation (EC) No 1907/2006 (REACH), Article 59.
Per- and poly-fluorinated compounds from C4 – C14 (PFAS) occur, for example, in soil and water repellent
finishes within textiles or can be introduced as contaminants (for example from water sources).
Categories of PFAS are shown in Table 1. Table 2 lists classes of regulated compounds (i.e. listed in a
Regulation) including acids, telomers, sulfonates and sulfonamidalcohols. Compounds of concern (i.e. not
listed yet in a Regulation) are shown in the informative Annex C.
