Cleanrooms and associated controlled environments - Classification of air cleanlinessBS EN ISO 14644 1: 1999 Cleanrooms and associated controlled environments. Classification of air cleanliness BS EN ISO 14644 1: 1999 covers the classification of air cleanliness in cleanrooms and associated controlled environments. This is based solely on the concentration of airborne particles. Only particle populations having cumulative distributions based upon threshold sizes ranging from 0. 1m to 5m are considered for classification purposes.
