PFAS certification testing

Testing standards

PFAS， Perfluoroalkyl and polyfluoroalkyl substances, due to their unique chemical structures, are difficult to degrade in the environment and may pose potential hazards to human health and the ecological environment. To control the use of PFAS, countries and international organizations have developed corresponding certification testing standards.

EU standard: The EU Regulation on Persistent Organic Pollutants imposes strict restrictions on the use and emission of certain PFAS substances. In the testing of textiles and leather products, precise determination of PFAS residue is required to ensure compliance with regulatory requirements. During detection, liquid chromatography tandem mass spectrometry (LC-MS/MS) is commonly used, which has high sensitivity and can accurately identify and quantitatively detect various PFAS compounds. The US Environmental Protection Agency (EPA) has developed a series of testing methods and regulatory requirements for PFAS. For example, in the detection of drinking water, EPA has set detection limits for specific PFAS substances, and qualitative and quantitative analysis of PFAS in water samples is carried out through solid-phase extraction combined with high-resolution mass spectrometry technology. In the detection of food contact materials, advanced analytical techniques are also used to ensure that the migration of PFAS in food contact materials does not exceed the standard.

Applicable products

Textiles and leather products: Waterproof and oil resistant textiles and leather products often use finishing agents containing PFAS, which require PFAS certification testing to ensure that the residual PFAS content in the product meets the standard and avoid potential risks to consumer health.

Food packaging materials: Paper, plastic, and other materials used in food packaging that contain PFAS may migrate into food. Through PFAS certification testing, the safety of food packaging materials can be ensured, preventing PFAS from affecting food safety.

Electronic products: Some coatings and sealing materials of electronic products may contain PFAS. PFAS certification testing can ensure that electronic products will not release excessive PFAS into the environment during production and use, reducing the harm to the ecological environment.
