ISO 14644‑1 Overview and Recent Revision
The ISO 14644‑1 standard (2015 edition) is the global benchmark for cleanroom air cleanliness, defining nine classes (ISO Class 1–9) based on airborne particle counts. Each class sets maximum concentrations of particles ≥0.1, 0.2, 0.3, 0.5, 1.0, or 5.0 μm in a cubic meter of air. In practice, lower class numbers mean cleaner environments. For example, ISO Class 5 (used in … Read more

Validation of Fumigation in Clean Room Areas in Pharmaceutical Industries
An uncontaminated environment is essential in pharmaceutical manufacture. Clean rooms created with strict ISO guidelines are engineered with the intent of reducing particulate and microbial contamination in drug manufacturing processes. However, microbial contamination may still be present owing to inadequate cooling, cleaning regimens, or even both. These controlled environments must comply with regulations which means … Read more
