| Resumen: | This part of ISO 14644 establishes the classification of air cleanliness in terms of concentration of airborne particles in cleanrooms and clean zones; and separative devices as defined in ISO 14644-7:2004. Only particle populations having cumulative distributions based on threshold (lower limit) particle sizes ranging from 0,1 µm to 5 µm are considered for classification purposes. The use of light scattering (discrete) airborne particle counters (LSAPC) is the basis for determination of the concentration of airborne particles, equal to and greater than the specified sizes, at designated sampling locations. This part of ISO 14644 does not provide for classification of particle populations that are outside the specified lower threshold particle-size range, 0,1 µm to 5 µm. Concentrations of ultrafine particles (particles smaller than 0,1 µm) are addressed in ISO 14644-12, which specifies air cleanliness by nano-scale particles, while an M descriptor (see Annex C) may be used to quantify populations of macroparticles (particles larger than 5 µm). This part of ISO 14644 cannot be used to characterize the physical, chemical, radiological, viable or other nature of airborne particles. La présente partie de cette norme européenne définit la classification de la propreté particulaire des salles propres et des espaces à empoussièrement contrôlé, pour trois états d'occupation possibles, selon la concentration des particules en suspension dans l'air. |
