is the globally recognized international standard that dictates the specific metrology and test methods used to characterize, qualify, and validate cleanrooms and associated controlled environments. While Part 1 of the standard defines the classification of air cleanliness by particle concentration, ISO 14644-3 focuses exclusively on the practical test protocols required to prove a cleanroom’s physical performance.
