La présente partie de l'ISO 14644 comprend la classification de la propreté de l'air des salles propres et environnements maîtrisés apparentés exclusivement en termes de concentration des particules en suspension dans l'air. Pour l'application de cette classification, on ne considère que les populations de particules présentant une distribution cumulée dont le seuil inférieur de sensibilité se situe dans l'étendue granulométrique de 0,1 µm à 5 µm. La présente partie de l'ISO 14644 ne donne pas la classification des populations de particules sortant de l'étendue granulométrique de référence de 0,1 µm à 5 µm. Les concentrations de particules ultrafines (plus petites que 0,1 µm) et de macroparticules (plus grandes que 5 µm) peuvent être utilisées pour quantifier ces populations en terme de descripteurs U et M. La présente partie de l'ISO 14644 n'est pas applicable pour caractériser la nature physique, chimique, radiologique ou viable des particules en suspension dans l'air. NOTE La distribution granulométrique réelle de particules par taille à l'intérieur de l'étendue de référence n'est pas habituellement prévisible et est typiquement variable avec le temps.
