Air filters for general ventilation - Part 2: Measurement of fractional efficiency and air flow resistance (ISO 16890-2:2016)
ISO 16890-2:2016 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 for use in conjunction with ISO 16890‑1, ISO 16890‑3 and ISO 16890‑4.
The test method described in this part of ISO 16890 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 inch × 24,0 inch).
ISO 16890 (all parts) 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 ISO 16890 (all parts).
NOTE The lower limit for this test procedure is set at a minimum ePM10 efficiency of 20 % since it will be very difficult for a test filter element below this level to meet the statistical validity requirements of this procedure.
Air filter elements outside of this aerosol fraction are evaluated by other applicable test methods, (see ISO 29463 (all parts)).
Filter elements used in portable room-air cleaners are excluded from the scope.
The performance results obtained in accordance with ISO 16890 (all parts) cannot by themselves be quantitatively applied to predict performance in service with regard to efficiency and lifetime.

Filtres à air de ventilation générale - Partie 2: Mesurage de l'efficacité spectrale et de la résistance à l'écoulement de l'air (ISO 16890-2:2016)
ISO 16890-2:2016 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 d'un filtre à air de ventilation générale.
Elle est destinée à être utilisée conjointement avec l'ISO 16890‑1, l'ISO 16890‑3 et l'ISO 16890‑4.
La méthode d'essai décrite dans la présente partie de l'ISO 16890 est applicable pour des débits d'air compris entre 0,25 m3/s (900 m3/h, 530 ft3/min) et 1,5 m3/s (5400 m3/h, 3178 ft3/min), en se référant à un banc d'essai ayant une surface frontale nominale de 610 mm x 610 mm (24 inch x 24 inch).
L'ISO 16890 (toutes les parties) concerne les éléments filtrants de 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 l'ISO 16890 (toutes les parties).
NOTE Pour ce mode opératoire, la limite inférieure 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.
En dehors de ces fractions d'aérosol, les éléments filtrant sont évalués par d'autres méthodes d'essai applicables (voir l'ISO 29463 (toutes les parties)).
Les éléments filtrants utilisés dans les épurateurs d'air ambiant portatifs sont exclus du domaine d'application.
Les résultats de performance obtenus conformément à l'ISO 29463 (toutes les parties) ne peuvent pas être utilisés quantitativement pour prédire les performances en service, en ce qui concerne l'efficacité et la durée de vie.
Zračni filtri pri splošnem prezračevanju - 2. del: Merjenje frakcijske učinkovitosti in odpornosti proti toku zraka (ISO 16890-2:2016)
Ta evropski standard se uporablja za zračne filtre delcev za splošno prezračevanje, katerih začetna učinkovitost v zvezi z delci velikosti 0,4 μm je manj kot 99 %. Filtri, ki se uporabljajo pri prezračevanju nizkih stanovanjskih stavb ali premični čistilniki zraka v prostorih so izključeni s področja uporabe tega standarda. Opisuje tehnične specifikacije, zahteve in metodo preskušanja za merjenje frakcijske učinkovitosti in odpornosti proti toku zraka. Metoda je uporabna za tok zraka med 0,25 m³/s (900 m³/h, 530 ft³/min) in 1,5 m³/s (5400 m³/h, 3178 ft³/min) v preskusnih ceveh z nazivno površino 0,61 m x 0,61 m. Boljši filtri z začetno učinkovitostjo nad 99 % glede na delce velikosti 0,4 µm se preskušajo in razvrščajo v skladu z drugimi standardi (glej ISO 29463, del 1-5). Filtri v skladu s to serijo standardov se ocenjujejo po njihovi učinkovitosti odstranjevanja delcev aerosolov PM10, PM2.5 in PM1. Učinkovitost zbiranja delcev vložka filtra se meri kot funkcija velikosti delcev v razponu od 0,3 do 10 μm pri praznem in nekondicioniranem vložku filtra. V drugem koraku je treba polni vložek filtra kondicionirati (izprazniti) v koraku umetnega staranja, s čimer se zagotovijo informacije o intenzivnosti elektrostatičnega mehanizma odstranjevanja. Rezultati drugega koraka se uporabljajo za izračun povprečne učinkovitosti v razponih velikosti PM10, PM2.5 in PM1 s ponderiranjem vrednosti frakcijske učinkovitosti glede na porazdelitev standardizirane in normalizirane velikosti delcev povezane frakcije zunanjega aerosola. V tem standardu je določena ta porazdelitev standardizirane in normalizirane velikosti delcev.
