High efficiency air filters (EPA, HEPA and ULPA) - Part 5: Determining the efficiency of filter elements

This European Standard applies to efficient particulate air filters (EPA), high efficiency particulate air filters (HEPA) and ultra low penetration air filters (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 test aerosol, and allows a standardized classification of these filters in terms of their efficiency.
This part of the EN 1822 series deals with measuring the efficiency of filter elements, specifying the conditions and procedures for carrying out tests, describing a specimen test apparatus and its components, and including the method for evaluating test results.

Schwebstofffilter (EPA, HEPA und ULPA) - Teil 5: Abscheidegradprüfung des Filterelements

Diese Europäische Norm gilt für Hochleistungs-Partikelfilter (EPA) Schwebstofffilter (HEPA) und
Hochleistungs-Schwebstofffilter (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 Prüfaerosols fest und ermöglicht eine einheitliche Klassifizierung der Schwebstofffilter
nach dem Abscheidegrad.
Dieser Teil der Normenreihe EN 1822 behandelt die Abscheidegradprüfung von Filterelementen mit Angabe
der Bedingungen und Verfahren zur Durchführung der Prüfung sowie mit der Beschreibung eines Prüfgerätes
einschließlich ihrer Komponenten und des Verfahrens zur Auswertung der Messergebnisse.

Filtres à air à haute efficacité (EPA, HEPA et ULPA) - Partie 5: Mesure de l'efficacité de l'élément filtrant

La présente Norme européenne est applicable aux filtres à air à haute efficacité (EPA), à très haute efficacité (HEPA) et à très faible pénétration (ULPA), utilisés dans le domaine de la ventilation et de la climatisation ainsi que dans des procédés techniques, tels que les applications en salle blanche ou de 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 liquide et permet une classification normalisée de ces filtres en fonction de leur efficacité.
Cette partie de la série des EN 1822 traite de la mesure de l'efficacité des éléments filtrants, elle spécifie les conditions et les modes opératoires des essais, décrit un exemple d'appareillage d'essai et ses éléments, et inclut la méthode d'évaluation des résultats d'essai.

Visoko učinkoviti zračni filtri (EPA, HEPA in ULPA) - 5. del: Določanje učinkovitosti filtrskih elementov

Ta evropski standard velja za učinkovite zračne filtre drobnih delcev (EPA), visoko učinkovite zračne filtre drobnih delcev (HEPA) in zračne filtre z ultra nizko penetracijo (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 ter omogoča standardizirano klasifikacijo teh filtrov glede na njihovo učinkovitost. Ta del serije EN 1822 obravnava merjenje učinkovitosti filtrskih elementov, določa pogoje in postopke za opravljanje preskusov, opisuje vzorčno opremo za preskušanje in njene komponente ter vključuje metodo za vrednotenje rezultatov preskusa.
