Test method to measure the efficiency of air filtration media against spherical nanomaterials - Part 1: Size range from 20 nm to 500 nm (ISO 21083-1:2018)

This document specifies the testing instruments and procedure for determining the fractional filtration efficiencies of flat sheet filter medium against airborne nanoparticles in the range of 20 nm to 500 nm. The testing methods in this document are limited to spherical or nearly-spherical particles to avoid uncertainties due to the particle shape.

Dieses Dokument legt die Prüfinstrumente und Prüfverfahren für die Bestimmung des Filtrationswirkungsgrads von planen Filtermedien gegen Nanoschwebstoffpartikel im Größenbereich zwischen 20 nm und 500 nm fest. Die Prüfverfahren in diesem Dokument sind auf kugelförmige oder fast kugelförmige Partikel beschränkt, um Unsicherheiten aufgrund der Partikelform zu vermeiden.

Méthode d'essai pour mesurer l'efficacité des médias de filtration d'air par rapport aux nanomatériaux sphériques - Partie 1: Spectre granulométrique de 20 nm à 500 nm (ISO 21083-1:2018)

Le présent document spécifie les instruments et modes opératoires d'essai à utiliser pour la détermination des efficacités fractionnelles de filtration des médias filtrants plans par rapport à des nanoparticules en suspension dans l'air dans la plage granulométrique de 20 nm à 500 nm. Les méthodes d'essai décrites dans le présent document sont limitées aux particules sphériques ou quasi-sphériques afin d'éviter toute incertitude liée à la forme des particules.
