Since 30 June 2018, the new test standard ISO 16890 for filter evaluation and classification has replaced the previous standard EN 779 with exclusive validity.
From December 2016 until June 30th, there was a transitional period in which both standards existed in parallel.
In the future, the filtration efficiencies will be determined with regard to particulate matter classes PM1, PM2,5 and PM10.
