: Checking the integrity of installed filter systems (HEPA/ULPA) to ensure no bypass leakage.

While classification (Part 1) tells you how clean your air is at a specific moment, Part 3 specifies the physical tests required to validate that your cleanroom's mechanical systems are actually working. Key reasons to follow Part 3 include: Validation & Commissioning: Proving a new cleanroom meets design specs. Periodic Re-testing:
