Resumen:
This part of ISO 14644 covers the classification of air cleanliness in cleanrooms and associated controlled environments exclusively in terms of concentration of airborne particles. 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 discrete-particle airborne counting and sizing instruments 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 of the specified particle-size range, 0,1 µm to 5 µm. Concentrations of ultrafine particles (particles smaller than 0,1 µm) and macroparticles (particles larger than 5 µm) may be used to quantify these populations in terms of U descriptors and M descriptors (see 3.3.1 and 3.3.2), respectively. This part of ISO 14644 cannot be used to characterise the physical, chemical, radiological or viable 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.
