Is there a policy for how long an answer can remain published after its supporting certificate expires?
The company publishes no such policy; a certificate is current according to the body that issued it, and each answer in this library carries the date it was last reviewed.
The certificates the company relies on are named on the Validation page with the issuing body and the number, including OEKO-TEX Service GmbH, Certificate 17.0.25812, and Eurovent Certita Certification, Certificate No. 15.06.011. That body's own record is the one that decides it. Both numbers can be checked at source: certificate 17.0.25812 in OEKO-TEX’s public label check, and Certificate No. 15.06.011 in the Eurovent Certita Certification certified product directory. Certificate No. 15.06.011 covers a ten-pocket bag filter, not a flat panel filter, and a rating belongs to the construction that was tested and to the conditions in the report.
