The cleanliness of an environment is vital in industries where contamination can have significant consequences. To standardize these classifications, the International Organization for Standardization (ISO) established the guidelines known as ISO 14644. This standard defines cleanroom classes based on the allowable particle concentration per cubic

Cleanroom classification systems utilize a standardized framework for defining and achieving specific levels of air cleanliness. These systems categorize cleanroom environments based on the number of debris allowed per unit volume of air. By adhering to established classification standards, such as ISO 14644 or Federal Standard 209E, facilities can
