Overview

EN ISO 16373-3:2014 - "Textiles - Dyestuffs - Part 3" specifies a laboratory method for the detection and quantitative determination of certain carcinogenic dyestuffs in dyed, printed or coated textile products. The method uses an extraction step with a triethylamine/methanol solvent followed by chromatographic analysis (HPLC with diode-array detection or mass spectrometry). This standard was adopted by CEN and published in 2014 to support regulatory compliance and safety testing of textile articles.

Key topics and technical requirements

Scope: Detection and quantification of the dyestuffs listed in Table 1 of the standard (examples include C.I. Basic Red 9, C.I. Disperse Orange 11, C.I. Disperse Yellow 3, C.I. Acid Red 114).

Principle: Ultrasonic-assisted extraction of dye from textile matrix using triethylamine/methanol, followed by analysis by HPLC‑DAD or HPLC‑MSD.

Apparatus & conditions: Describes required equipment such as an ultrasonic bath (heated to 50 ± 5 °C; typical output and frequency specified), coil condenser, rotary evaporator, volumetric glassware and an HPLC system.

Reagents: Lists analytical-grade solvents (methanol, acetonitrile, hexane), 0.25% triethylamine in methanol, and a 10 mmol/L ammonium acetate aqueous solution. Procedures for preparing standard solutions and calibration curves are included.

Procedure elements: Test specimen sampling and preparation, extraction, chromatographic separation, detection, identification and quantification, and instructions for reporting results.

Safety: Explicit warnings that targeted dyestuffs are known or suspected carcinogens; mandates appropriate health & safety and waste-disposal practices.

Supporting material: Annex A covers chromatographic analysis details; Annex B provides round-robin test results (interlaboratory data).

Applications and users

Who uses it: Textile testing laboratories, manufacturers and dye formulators, quality assurance teams, importers/retailers, regulatory bodies, and compliance/forensic laboratories.

Practical uses:

Compliance testing against national and international restrictions on carcinogenic dyestuffs.
Incoming quality control and supplier verification.
Investigations of consumer complaints or suspected non‑compliant products.
Supporting declarations for market access in jurisdictions that regulate hazardous dyestuffs.

ISO 16373-2 - Complementary extraction method using pyridine-water for a broader range of extractable dyestuffs (including allergenic and carcinogenic dyes).

By following EN ISO 16373-3:2014 laboratories obtain a reproducible, validated procedure for extracting and quantifying specific carcinogenic colorants in textiles, helping ensure product safety and regulatory compliance.
