Clean Room Compliance Made Simple: Navigating ISO 14644 Requirements

WHAT IS A CLEAN ROOM?

A clean room is a controlled environment designed to maintain a specific level of cleanliness through purified air ventilation. These rooms are essential for producing products that require strict contamination control, minimizing risks from particulates, microbes, or pyrogens. 

APPLICATIONS OF CLEAN ROOMS

Clean rooms play a critical role in: 

• Hospitals and surgery rooms
• IP Pharmacies
• Laboratories
• Pharmaceutical and food industries
• Polymer industries
• Laminar flow operations
• Biosafety Cabinet operations 

WHY CLEAN ROOM VALIDATION MATTERS

In highly regulated sectors like medical devices and pharmaceuticals, validation ensures that critical processes occur under controlled conditions. This guarantees products of superior quality, reliability, and safety for end users. 

PRINCIPLES OF CLEAN ROOM VALIDATION 

To confirm environmental control, validation includes: 

• Air supply, flow, and visualization
• Air velocity and pressure
• Air exchange rate
• Particle count test (non-viable test)
• HEPA/ULPA filter leakage tests
• Humidity and temperature checks
• Viable Count test (microbial air)
• light (lux) test and
• Noise levels test 

STANDARDS THAT GUIDE US 

The most relevant standard is ISO 14644, which covers: 

Part 1: Classification of air cleanliness by particle concentration (ISO 14644-1: 2015) 

Part 2: Monitoring to provide evidence of cleanroom Performance related to air cleanliness by particle     concentration (ISO 14644-1: 2015) 

Part 3: Test methods (ISO 14644-1: 2019)
