Описание (английский):

This document specifies a test method for the determination of total amount of halogens (including fluorine, chlorine, bromine and iodine) present in textile products by combustion and ion chromatography (C-IC). This document is applicable to all materials of textile products which are combustible, e.g. fibres, fabrics, plastic components (including coating), wood.

Overview

ISO 20999:2026 establishes a standardized method for determining the total amount of halogens-fluorine, chlorine, bromine, and iodine-in textile products using the combustion and ion chromatography (C-IC) method. Developed by ISO Technical Committee 38 (Textiles) in collaboration with CEN, this international standard is applicable to all combustible materials in textile products, including fibres, fabrics, plastic components (such as coatings), and wood. The purpose of ISO 20999:2026 is to provide a reliable, verifiable approach for analyzing potentially harmful halogen content in textiles, aiding regulatory compliance, quality assurance, and material characterization.

Key Topics

Scope of Application

Suited for all textile materials that are combustible, such as yarns, fabrics, plastics, and coated or wooden components.
Measures the total concentration of all four main halogens: fluorine, chlorine, bromine, and iodine.

Test Principle

Test specimens are combusted under controlled high temperatures in an oxygen-rich atmosphere.
The resulting hydrogen halide gases are captured in an absorption solution.
Halogen content is quantitatively determined using ion chromatography.

Preparation and Safety

Samples must be homogeneously mixed and cut to standardized sizes for consistency.
Laboratory personnel must use halogen-free materials and appropriate personal protective equipment to prevent contamination.

Reporting

Accurate documentation, including reference to ISO 20999:2026, sample identification, mass fractions of each halogen, deviations, and test date, is required.

Limitations

The method does not differentiate between organic and inorganic halogens.
It cannot specifically identify or quantify perfluorinated and polyfluorinated alkyl substances (PFAS), but high halogen content can indicate their possible presence.

Applications

Regulatory Compliance

Supports adherence to legal limits regarding halogenated substances in consumer textiles.
Useful for screening products for restricted substances such as PFAS and certain flame retardants or biocides.

Quality Control

Ensures material uniformity and safety in production processes.
Allows textile manufacturers, importers, and retailers to verify product claims regarding halogen content.

Environmental and Safety Assessments

Provides baseline data for environmental risk evaluations of textiles.
Assists in the identification of potentially hazardous materials for further analysis or mitigation.

Research and Development

Facilitates comparison of different material formulations and the effectiveness of dehalogenation processes.

Regulatory Framework and Testing Guides

Reference to legal requirements on halogens in textiles across various international markets.
Utilized in conjunction with local or regional bans or thresholds on substances of concern in consumer goods.

ISO 20999:2026 serves as an essential tool for textile laboratories, regulatory bodies, manufacturers, and quality assurance professionals to ensure the safety, regulatory compliance, and marketability of textile products by reliably determining total halogen content through combustion and ion chromatography analysis.
