Cleanrooms and associated controlled environments - Classification of surface cleanliness by particle concentration1 Scope This part of ISO 14644 establishes the classification of cleanliness levels on solid surfaces by particle concentration in cleanrooms and associated controlled environment applications. Recommendations on testing and measuring methods, as well as information about surface characteristics, are given in Annexes A to D. This part of ISO 14644 applies to all solid surfaces in cleanrooms and associated controlled environments, such as walls,
