Standards and guidelines

• Test according to ISO 16890; international standard for general ventilation and air conditioning; classification of arrestance efficiency based on the measured fractional arrestance efficiency, which is processed into a reporting system for the fine dust arrestance efficiency (ePM)
• For fine dust filters, the fractional arrestance efficiency of a certain size range is determined by aerosols (DEHS and KCl)
• The filters are classified into filter groups ISO ePM10 and ISO ePM1 depending on the tested values
• Testing of particulate filters according to EN 1822-1 and ISO 29463-2 to ISO 29463-5 (EPA, HEPA and ULPA particulate filters): standards for the testing of filtration performance in the manufacturer’s factory, particle counting method using a liquid test aerosol
• Uniform classification of particulate filters according to efficiency, using a test aerosol whose average particle size lies within the minimum efficiency (MPPS)
• Particulate filters are classified according to the values determined for the local filtration efficiency and the overall filtration efficiency as EPA (filter classes E10, E11, E12), HEPA (filter classes H13, H14) or ULPA (filter classes U15, U16, U17)
• Hygiene conformity: VDI 6022, VDI 3803, DIN 1946 Part 4, ÖNORM H 6020, SWKI VA 104-01 and SWKI 99-3 and EN 16798
• Certificate of conformity for correct use in areas with a potentially explosive atmosphere in accordance with guideline 2014/34/EU and compliance with basic health and safety requirements in accordance with EN 80079-36:2016 and EN 80079-37:2016
