Every batch we make. Tested. Published.
We test every production batch for PFAS at an independent, ISO/IEC 17025-accredited lab before it ships. The actual lab certificate goes here — batch number, test date, lab name, every analyte, every reporting limit, signed by the technician. Not a re-typed summary. Not a screenshot with the lab cropped out. The real PDF.
How to read a WOVAE batch report
- Batch ID — for example
2027-04-A. The first batch produced in April 2027. Every pair you receive has the batch ID printed on the inside care tag. - Lab + report number — fully visible. You can call the lab and verify the report number is real. (Some competitors crop this out. We don’t.)
- Two test methods, side by side. First, total organic fluorine via combustion + ion chromatography (a screen — broad but coarse). Second, a targeted PFAS panel by LC-MS/MS that names each compound (PFOS, PFOA, PFNA, PFHxS, 6:2 FTS, 8:2 FTOH, etc.) with a CAS number and a 10 ppb reporting limit per analyte.
- “ND” means not detected at the lab’s reporting limit. It does not mean mathematically zero. ND at 10 ppb is roughly 1,000× stronger evidence than ND at 10 ppm. Always check the limit.
- PASS / FAIL. If a batch fails to clear, that batch is not sold. We’d publish the failing report too.

Methodology
We use two test methods on every batch: EN 14582:2016 for total organic fluorine (combustion + ion chromatography, 20 ppm reporting limit) and EN ISO 23702-1:2018 for targeted PFAS analytes via HPLC-MS/MS at a 10 ppb per-analyte reporting limit. Together they cover the screen-and-confirm approach used in the peer-reviewed PFAS-in-textiles literature. Questions or want to verify a report? [email protected].
