ISO 14644-3:2019 defines standardized testing procedures for qualifying cleanrooms, covering airflow, pressure, and filter leakage in as-built, at-rest, and operational states. The 2019 revision simplified procedures, including updated filter leak testing, while shifting particle classification methods entirely to ISO 14644-1. For more details, visit ISO Standards Store.

What ISO 14644‑3 covers (high level)

Airborne particle concentration measurements: How to measure and count particles of specified sizes at selected locations and heights.
Airflow and pressure tests: Methods for assessing airflow patterns, air change rates, and differential pressures between zones.
Leak and filter integrity tests: Procedures to test HEPA/ULPA filters and ductwork leakage.
Recovery and robustness testing: How quickly a room returns to controlled conditions after disturbance, and how it behaves under typical operational stresses.
Environmental tests: Temperature, humidity, and illumination measurement methods relevant to controlled environments.
Sampling plans and statistical considerations: Where and how many samples to take, and how to interpret results against limits.

Introduction: What is ISO 14644?

If you work in pharmaceuticals, aerospace, medical devices, or electronics manufacturing, you know the phrase "ISO 14644" by heart. This is the international gold standard for cleanrooms and controlled environments.

But searching for "iso 146443pdf" (often a typo for ISO 14644 PDF) usually leads to confusion. Are you looking for Part 1? Part 2? A free bootleg copy? Or the official document? One-page Monitoring Plan template (fillable)
