Popis
BS EN 1822-1:2019
This standard BS EN 1822-1:2019 High efficiency air filters (EPA, HEPA and ULPA) is classified in these ICS categories:
- 23.120 Ventilators. Fans. Air-conditioners
- 13.040.40 Stationary source emissions
This document applies to high efficiency particulate and ultra-low penetration air filters (EPA, HEPA and ULPA) used in the field of ventilation and air conditioning and for technical processes, e.g. for applications in clean room technology or pharmaceutical industry.
It establishes a procedure for the determination of the efficiency on the basis of a particle counting method using a liquid (or alternatively a solid) test aerosol and allows a standardized classification of these filters in terms of their efficiency, both local and integral efficiency.
