The ISO 14644 series forms the international foundation for cleanroom design, classification, and operation. The series includes multiple parts that cover the entire lifecycle:

: Measures how quickly the cleanroom returns to its target cleanliness level after being disturbed. iso 146443pdf 2021

: Uses non-residue smoke to visually confirm that air flows protect critical work zones without turbulence. – Regulators (FDA, EMA, WHO, NMPA) expect facilities

– Regulators (FDA, EMA, WHO, NMPA) expect facilities to follow current ISO test methods during inspections. Without the correct standard, you cannot demonstrate compliance.
