Parameters (quantitative): total perfluorooctanesulfonic acid (CAS 1763-23-1) [mg/kg], total perfluorooctanoic acid (CAS 335-67-1) [mg/kg], total perfluorononanoic acid (CAS 375-95-1) [mg/kg], total perfluorohexane sulfonic acid (CAS 355-46-4) [mg/kg], total perfluorohexanoic acid (CAS 307-24-4) [mg/kg], total perfluorodecanoic acid (CAS 335-76-2) [mg/kg], total perfluorundecanoic acid (CAS 2058-94-8) [mg/kg], total perfluorododecanoic acid (CAS 307-55-1) [mg/kg], total perfluorotridecanoic acid (CAS 72629-94-8) [mg/kg], total perfluorotetradecanoic acid (CAS 376-06-7) [mg/kg], total perfluorobutanoic acid (CAS 375-22-4) [mg/kg], total perfluoropentanoic acid (CAS 2706-90-3) [mg/kg], total perfluoroheptanoic acid (CAS 375-85-9) [mg/kg], total perfluorobutane sulfonic acid (CAS 375-73-5) [mg/kg], 6:2 FTOH (CAS 647-42-7) [mg/kg], 8:2 FTOH (CAS 678-39-7) [mg/kg], 10:2 FTOH (CAS 865-86-1) [mg/kg], 12:2 FTOH (CAS 39239-77-5) [mg/kg], 6:2 FTS (CAS 27619-97-2) [mg/kg], total fluorine (TF) [mg/kg] Article Number: 2011536 Description: Legal limit values for toxic, carcinogenic, mutagenic and other such substances generally apply only to finished end products, e.g. textiles, footwear, plastics, etc. However, raw materials, auxiliary materials and additives used during the industrial processing of these products have not, to date, been tested for such prohibited substances at all, even though it is precisely through their use that such substances are introduced into the end products. If only ‘clean’ chemicals are used during the manufacturing process, manufacturers can take a major step towards ensuring compliance with the legal requirements for end products at an early stage. Through proficiency tests on industrial chemicals such as dyeing post-treatment agents, water-repellent agents and auxiliary materials in the tanning industry, the DRRR supports laboratories and manufacturers in the analysis of such formulations. Testing for TF e.g. possible with ASTM D7359 Category: chemical-physical testing Environmental analytics chemicals and chemical formulations Accreditation: This proficiency test is not included in the scope of the accreditation.
