High efficiency air filters (EPA, HEPA and ULPA) - Part 1: Classification, performance testing, marking
This European Standard 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.
Schwebstofffilter (EPA, HEPA und ULPA) - Teil 1: Klassifikation, Leistungsprüfung, Kennzeichnung
Diese Europäische Norm gilt für Hochleistungs-Partikelfilter und Hochleistungs-Schwebstofffilter (EPA, HEPA
und ULPA) im Bereich der Raum- und Prozesslufttechnik, z. B. Anwendungen in der Reinraumtechnik oder in
der pharmazeutischen Industrie.
Sie legt ein Verfahren zur Prüfung des Abscheidegrades auf Basis von Partikelzählverfahren unter
Verwendung eines flüssigen (oder alternativ eines festen) Prüfaerosols fest und ermöglicht eine einheitliche
Klassifizierung der Schwebstofffilter nach dem Abscheidegrad, sowohl nach dem integralen als auch nach
dem lokalen Abscheidegrad.
Filtres à air à haute efficacité (EPA, HEPA et ULPA) - Partie 1: Classification, essais de performance et marquage
La présente Norme européenne est applicable aux filtres à air à haute efficacité et à très faible pénétration (EPA, HEPA et ULPA) utilisés dans le domaine de la ventilation et de la climatisation, ainsi que dans des procédés techniques tels que la technique en salle blanche ou l’industrie pharmaceutique.
Elle définit une méthode de détermination de l’efficacité, à partir d’une méthode du comptage de particules à l’aide d’un aérosol d’essai avec des particules liquides (ou solides) et permet une classification normalisée de ces filtres en fonction de leur efficacité, locale ou globale.
Visoko učinkoviti zračni filtri (EPA, HEPA in ULPA) - 1. del: Klasifikacija, preskušanje lastnosti, označevanje
Ta evropski standard velja za visoko učinkovite zračne filtre drobnih delcev in zračne filtre z ultra nizko penetracijo (EPA, HEPA in ULPA), ki se uporabljajo na področju prezračevanja in klimatizacije ter za tehnične postopke, npr. za naprave v tehnologiji čistega prostora ali farmacevtski industriji. Vzpostavlja postopek za določitev učinkovitosti na osnovi metode štetja delcev z uporabo tekočega testnega aerosola (ali v trdnem stanju kot druga možnost) ter omogoča standardizirano klasifikacijo teh filtrov glede na njihovo učinkovitost, tako lokalno kot celovito učinkovitost.

Class E 11;
Class E 12. Group H filters are subdivided in two Classes:
Class H 13;

Class U 15;
Class U 16;
Class U 17. 6 Requirements 6.1 General The filter element shall be designed or marked so as to prevent incorrect mounting. The filter element shall be designed so that when correctly mounted in the ventilation duct, no leak occurs along the sealing edge. If, for any reason, dimensions do not allow testing of a filter under standard test conditions, assembly of two or more filters of the same type or model is permitted, provided no leaks occur in the resulting filter. 6.2 Material The filter element shall be made of suitable material to withstand normal usage and exposures to those temperatures, humidities and corrosive environments that are likely to be encountered. The filter element shall be designed so that it will withstand mechanical constraints that are likely to be encountered during normal use. Dust or fibres released from the filter media by the air flow through the filter element shall not constitute a hazard or nuisance for the people (or devices) exposed to filtered air. 6.3 Nominal air volume flow rate The filter element shall be tested at its nominal air volume flow rate for which the filter has been designed by the manufacturer. 6.4 Pressure difference The pressure difference across the filter element is recorded at the nominal air volume flow rate. 6.5 Filtration performance The filtration performance is expressed by the efficiency or the penetration of MPPS particles.

7 Test methods 7.1
Test rigs The test rigs are described in detail in EN 1822-3, EN 1822-4 and EN 1822-5. The individual methods of measurement and the measuring instruments are described in EN 1822-2. 7.2 Test conditions The air in the test channel used for testing shall comply with the following requirements: Temperature: (23 ± 5) °C; Relative humidity < 75 %. The temperature shall remain constant during the entire test procedure within ± 2 °C the relative humidity within ± 5 %. The cleanliness of the test air shall be ensured by appropriate pre-filtering, so that in operation without addition of aerosol the particle number concentration measured with the particle counting method is less than 350 000 m-3. The test specimen shall have the same temperature as the test air. SIST EN 1822-1:2010
