ISO/AWI 16890-5 2020-10-22 Air filters for general ventilation - Part 5: Measurement of fractional efficiency and air flow resistance for flat sheet filter media More  Comment 
ISO/AWI 23137-1 2020-10-15 Requirements for aerosol filters used in nuclear facilities against specified severe conditions - Part 1: General requirements More  Comment 
DIN EN ISO 29463-5 rev 2020-01-31 The series ISO 29463 contains requirements, fundamental principles of testing and the marking for high-efficiency particulate air filters with efficiencies from 95 % to 99,999 995 % that can be used for classifying filters in general or for specific use by agreement between users and suppliers. DIN EN ISO 29463-5 specifies the reference test procedure for determining the efficiency of filters at their most penetrating particle size (MPPS). It also gives guidelines for the testing and classification for filters with an MPPS of less than 0,1 µm (Annex B) and filters using media with (charged) synthetic fibres (Annex C). It is intended for use in conjunction with DIN EN 1822-1 rev, DIN EN ISO 29463-2, DIN EN ISO 29463-3 and DIN EN ISO 29463-4. More  Comment
