Once, a top-tier pharmaceutical plant struggled with a mysterious spike in product contamination. Despite their air filters being rated "Class 100" (ISO 5), 15% of their medicine vials were being rejected due to microscopic particles.

A smoke test or similar technique is used to verify that the airflow direction matches the design (e.g., that it flows from cleaner to less-clean areas). Who Should Use ISO 14644-3? iso 146443pdf
