Introduction to ISO 14644
ISO 14644 is a globally recognized standard for cleanrooms. It covers:
- Classification of air cleanliness
- Testing and monitoring protocols
- Operational and design requirements
Key benefits:
- Ensures sterile and contamination-free operations
- Helps achieve regulatory compliance (GMP, FDA, EU Annex 1)
- Provides guidance for equipment selection and workflow design
LENGE Clean Room systems, including laminar airflow units, dispensing booths, and HEPA filters, are designed to meet these standards.
History and Purpose of ISO 14644
ISO 14644 was first published in 1999 to replace federal standards (FED-STD-209E). The goal was to:
- Provide global consistency in cleanroom classifications
- Standardize monitoring and testing methods
- Facilitate compliance across industries
The standard ensures products, processes, and personnel are protected from particulate contamination.
Parts of ISO 14644
ISO 14644 is divided into multiple parts. Key sections include:
Each part provides specific requirements for cleanroom setup, monitoring, and operational compliance.

Max particles ≥5µm / m³ |
|
ISO 1 |
10 |
2 |
|
ISO 2 |
100 |
24 |
|
ISO 3 |
1,000 |
237 |
|
ISO 4 |
10,000 |
2,370 |
|
ISO 5 |
100,000 |
23,700 |
|
ISO 6 |
1,000,000 |
237,000 |
|
ISO 7 |
352,000,000 |
10,200,000 |
|
ISO 8 |
3,520,000,000 |
102,000,000 |
Key takeaway: Lower class numbers indicate cleaner environments. LENGE Clean Room products are designed to achieve ISO 5–ISO 8 standards efficiently.
ISO 14644-2: Monitoring and Testing
Monitoring ensures cleanrooms maintain required air cleanliness levels. Key tests include:
- Particle count testing using calibrated particle counters
- Differential pressure measurement
- Temperature, humidity, and airflow monitoring
- HEPA/ULPA filter integrity testing
Frequency: Daily, weekly, or monthly depending on the cleanroom class. LENGE systems integrate sensors and control panels for automated monitoring.
ISO 14644-3: Test Methods
ISO 14644-3 defines methods for measuring air cleanliness:
- Particle concentration tests
- Airflow velocity and uniformity
- Filter leakage tests
- Recovery tests after contamination
Accurate testing ensures regulatory compliance and prevents product contamination. LENGE HEPA filters and laminar flow systems support easy testing and validation.
ISO 14644-4: Design and Construction
Cleanroom design principles focus on:
- Unidirectional airflow to reduce cross-contamination
- Smooth, cleanable surfaces (stainless steel SUS304/316L)
- Minimized joints, seams, and corners
- Modular design for flexibility and maintenance
LENGE cleanroom modules, including dispensing booths and laminar airflow benches, comply with ISO 14644-4 design guidelines.
ISO 14644-5: Operations and Maintenance
Operational protocols ensure ongoing compliance:
- Routine cleaning schedules
- Personnel gowning and training
- Scheduled filter replacement (HEPA/ULPA)
- Environmental monitoring and data logging
Following ISO 14644-5 helps reduce contamination risk while optimizing workflow efficiency in pharmaceutical and laboratory settings.
ISO 14644-7: Separative Devices
Separative devices protect cleanrooms by controlling contamination entry:
- Pass boxes (static and dynamic)
- Air showers
- Transfer hatches
