Updated PFAS Test Method for Textile Products

SG 059/25

Updated per- and polyfluoroalkyl substances (PFAS) test method for textile products is now available from the European Committee for Standardization (CEN).

On April 30, 2025, the CEN made available on its website EN 17681-1:2025, an updated PFAS testing method standard for textile and textile products. This will replace the current EN 17681-1:2022 standard and be adopted by EU national bodies, such as the BSI in the UK and DIN in Germany.

EN 17681-1:2025 introduces a major shift in the analytical approach for detecting PFAS in textiles. The previous EN 17681-1/2:2022 methods utilized methanol extraction, which measures extractable PFAS analytes. However, these methods are insufficient for detecting side-chain fluorinated polymers, which are subject to EU regulatory restrictions when associated with compounds such as PFOA, C9–C14 PFCAs, and PFHxA-related substances regulated under EU REACH and POPs.

To address the gap, the new process in the methodology employs alkaline hydrolysis, a more advanced technique designed to break down polymeric fluorinated substances and detect a broader range of PFAS. It utilizes liquid chromatography and tandem mass spectrometry (LC-MS/MS) to identify and quantify specific PFAS, including those that can be released from side-chain fluorinated polymers after alkaline hydrolysis. Internal studies and data collected during the method development indicate that the new approach can identify significantly higher levels of certain PFAS analytes, particularly fluorotelomer alcohols (FTOHs), which are commonly present in treated textile materials. 

EN 17681-1:2025 is expected to modify the way PFAS are tested across the global textile industry. The method has already gained attention and endorsement from leading industry associations, brands and retailers. Some have already incorporated this method into their restricted substances lists (RSLs), while others are planning to do so once the standard is officially published.

This test method change is expected to have a significant impact in the industry as brands, retailers and suppliers strive for compliance with evolving regulatory requirements. By adopting the new method, stakeholders will gain more accurate and comprehensive data on PFAS content, enabling more informed decisions on product safety and regulatory compliance. Transitioning to the 2025 version of EN 17681-1 will not only enhance compliance with regulatory expectations but also strengthen businesses’ confidence in product safety.
