ISO 16890 replaces EN 779
EN 779 (classes G2–F9) was withdrawn in 2018 and replaced by ISO 16890. We classify all air-filtration media to ISO 16890. Indicative conversion:
Certified processes.
Konus Konex operates to international quality and environmental-management standards. Antistatic AGT-BT media carry a DEKRA EXAM certificate for use in ATEX zones. Declarations of conformity to EU 1935/2004 and 10/2011 for food-contact applications, and REACH, are provided on request.
