ISO 14644 is the globally recognized standard for cleanroom classification. It defines cleanroom classes based on the maximum allowable concentration of airborne particles per cubic meter.
ISO Class 3 to Class 6 cleanrooms are commonly used in semiconductor fabrication, pharmaceutical production, precision electronics, and advanced material processing. Each class has distinct requirements for air filtration, airflow design, and consumable compatibility.
For example, ISO Class 3 environments require extremely low particle generation, making material selection critical. Consumables used in such environments must exhibit ultra-low particle and ionic release to prevent process disruption.
Understanding cleanroom classification allows procurement teams and engineers to select appropriate consumables that align with operational and regulatory requirements.
