EN ISO 18254-1:2016 PDF

Overview

EN ISO 18254-1:2016 is an international standard developed by CEN and ISO, prescribing a precise method for the detection and quantification of alkylphenol ethoxylates (APEO) in textiles using High Performance Liquid Chromatography coupled with Mass Spectrometry (HPLC-MS). This standard is critical for compliance with regulatory requirements and for supporting environmental and human health protection by monitoring harmful APEOs such as nonylphenol ethoxylates (NPEOs) and octylphenol ethoxylates (OPEOs).

The document provides standardized procedures for extracting, detecting, and quantifying defined APEO chain lengths in textile samples. This enables consistent, reproducible results that support regulations including REACH, and ensures safety in leather and textile production.

Key Topics

• Alkylphenol Ethoxylates (APEO): Includes nonylphenol ethoxylates (NPEO) and octylphenol ethoxylates (OPEO), widely used as surfactants but are restricted in textiles due to their toxicity and persistence.
• Extraction and Analysis: Details a systematic method using methanol extraction and ultrasound, followed by detection with liquid chromatography-mass spectrometry (LC-MS).
• Targeted Chain Lengths: Quantification focuses on APEO congeners with 2 to 16 ethoxylate groups, supporting relevant limits and regulatory requirements.
• Data Reproducibility: Specifies calibration, standard preparation, and calculation protocols to ensure results can be reliably compared between laboratories.
• Regulatory Support: Aligns with REACH Annex XVII for restricted substances in the European Union, helping manufacturers meet compliance limits for hazardous chemicals in textiles.

Applications

This standard is widely applicable across the textile industry and related sectors, offering practical value in:

• Textile Manufacturing and Supply Chain: Detection and assessment of APEOs in raw materials, finished textile goods, and leather to ensure regulatory compliance and product safety.
• Environmental Monitoring: Supporting wastewater and effluent testing from textile facilities to prevent APEO pollution in water bodies, fulfilling environmental protection commitments.
• Laboratory Testing: Providing accredited laboratories and quality control teams with a harmonized protocol for evaluating APEO residues with high sensitivity and accuracy.
