Air filters for general ventilation - Part 2: Measurement of fractional efficiency and air flow resistance (ISO 16890-2:2022)
This document specifies the aerosol production, the test equipment and the test methods used for measuring fractional efficiency and air flow resistance of air filters for general ventilation.
It is intended to be used in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4.
The test method described in this document is applicable for air flow rates between 0,25 m3/s (900 m3/h, 530 ft3/min) and 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), referring to a test rig with a nominal face area of 610 mm × 610 mm (24.0 inches × 24.0 inches).
This document refers to particulate air filter elements for general ventilation having an ePM1 efficiency less than or equal to 99 % and an ePM10 efficiency greater than 20 % when tested as per the procedures defined within the ISO 16890 series.
NOTE The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it is very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.
This document is not applicable to filter elements used in portable room-air cleaners.
Luftfilter für die allgemeine Raumlufttechnik - Teil 2: Ermittlung des Fraktionsabscheidegrades und des Durchflusswiderstandes (ISO 16890-2:2022)
Dieses Dokument legt die Aerosolherstellung, die Prüfmittel und Prüfverfahren fest, die zur Ermittlung des Fraktionsabscheidegrads und des Strömungswiderstands von Luftfilter für die allgemeine Raumtechnik verwendet werden.
Es ist für die Anwendung in Verbindung mit ISO 16890 1, ISO 16890 3 und ISO 16890 4 vorgesehen.
Das in diesem Dokument beschriebene Prüfverfahren ist für Volumenströme zwischen 0,25 m3/s (900 m3/h, 530 ft3/min) und 1,5 m3/s (5 400 m3/h, 3 178 ft3/min) anwendbar, bei einem Prüfstand mit einer nominellen Anströmfläche von 610 mm × 610 mm (24 inch × 24 inch).
Dieses Dokument bezieht sich auf Partikelluftfilterelemente für die allgemeine Raumlufttechnik mit einem ePM1 Abscheidegrad von weniger als oder gleich 99 % und einem ePM10 Abscheidegrad von mehr als 20 % bei der Prüfung nach den in der Normenreihe ISO 16890 festgelegten Verfahren.
ANMERKUNG Die untere Grenze für dieses Prüfverfahren liegt bei einem ePM10 Mindest-Abscheidegrad von 20 %, da es für ein Prüffilterelement unterhalb dieses Niveaus schwer ist, die Anforderungen an die statistische Gültigkeit von diesem Verfahren zu erreichen.
Dieses Dokument ist nicht anwendbar auf Filterelemente, die in tragbaren Raumluftreinigern verwendet werden.
Filtres à air de ventilation générale - Partie 2: Mesurage de l'efficacité spectrale et de la résistance à l'écoulement de l'air (ISO 16890-2:2022)
Le présent document spécifie la production d'aérosol, l'équipement d'essai et les méthodes d'essai utilisés pour mesurer l'efficacité spectrale et la résistance à l'écoulement de l'air des filtres à air de ventilation générale.
Il est destiné à être utilisé conjointement avec l'ISO 16890‑1, l’ISO 16890‑3 et l’ISO 16890‑4.
La méthode d'essai décrite dans le présent document est applicable pour des débits d'air compris entre 0,25 m3/s (900 m3/h, 530 ft3/min) et 1,5 m3/s (5 400 m3/h, 3 178 ft3/min), en se référant à un banc d'essai ayant une surface frontale nominale de 610 mm × 610 mm (24.0 inches × 24.0 inches).
Le présent document concerne les éléments filtrants pour l’élimination des particules pour la ventilation générale ayant une efficacité ePM1 inférieure ou égale à 99 % et une efficacité ePM10 supérieure à 20 % lorsqu'ils sont soumis à essai selon les modes opératoires définis dans la série ISO 16890.
NOTE La limite inférieure pour ce mode opératoire d'essai est fixée à une efficacité minimale ePM10 de 20 % étant donné qu’il est très difficile pour un élément filtrant d’essai en dessous de ce niveau de respecter les exigences de validité statistique de ce mode opératoire.
Le présent document n’est pas applicable aux éléments filtrants utilisés dans les épurateurs d'air ambiant portatifs.
Zračni filtri pri splošnem prezračevanju - 2. del: Merjenje frakcijske učinkovitosti in odpornosti proti toku zraka (ISO 16890-2:2022)
Ta dokument določa proizvodnjo aerosola, preskusno opremo in preskusne metode, ki se uporabljajo za merjenje frakcijske učinkovitosti in odpornosti proti toku zraka zračnih filtrov pri splošnem prezračevanju. Predviden je za uporabo v povezavi s standardi ISO 16890-1, ISO 16890-3 in ISO 16890-4. Preskusna metoda, opisana v tem dokumentu, se uporablja za stopnje pretoka zraka med 0,25 m3/s (900 m3/h, 530 ft3/min) in 1,5 m3/s (5400 m3/h, 3178 ft3/min), pri čemer se uporablja preskusna oprema z nazivno površino 610 × 610 mm (24,0 × 24,0 palcev). Ta dokument se uporablja za vložke zračnih filtrov delcev pri splošnem prezračevanju, ki pri preskušanju v skladu s postopki, določenimi v skupini standardov ISO 16890, dosegajo učinkovitost 99 % ali manj glede na vrednosti ePM1 in več kot 20 % glede na vrednosti ePM10. OPOMBA: Spodnja meja, določena za ta preskusni postopek, je vsaj 20-odstotna učinkovitost glede na vrednost ePM10, saj je vložek zračnega filtra, ki ne dosega te stopnje, zelo težko preskusiti tako, da bi bile izpolnjene zahteve glede statistične veljavnosti v skladu s tem postopkom. Ta dokument se ne uporablja za vložke filtrov, ki se uporabljajo v prenosnih čistilnikih zraka v prostorih.
