ISO 8 Cleanroom
Controlled Environments for Critical Industries
ISO 8 Cleanrooms are controlled environments that meet specific cleanliness and operational standards as defined by the International Organization for Standardization (ISO). These cleanrooms are essential in various industries, including pharmaceuticals, biotechnology, Electronics, and aerospace, where even minor contamination can compromise product quality and safety.
Definition and Standards
ISO 8 Cleanrooms are classified as environments with a maximum allowable particulate level of 3,520 particles per cubic meter for particles that are 0.5 microns or larger. This classification is part of the broader ISO 14644-1 standard, which provides guidelines for Cleanroom design, operation, and monitoring.
Key Characteristics
① Air Quality
iso 8 cleanrooms must maintain specific air quality that limits airborne particles. Continuous monitoring ensures compliance with ISO Standards.
② Temperature Control
Temperature is maintained between 18°C to 24°C (64°F to 75°F) to reduce contamination risks and ensure optimal working conditions.
③ Personnel Protocols
Stringent gowning and hygiene protocols are required, including cleanroom garments, gloves, and facial masks.
④ Airflow & Filtration
hepa filters and controlled airflow patterns ensure effective contaminant management within the cleanroom environment.
Industry Applications
iso 8 cleanrooms are widely used in industries where product integrity is paramount:
- Pharmaceutical manufacturing
- Medical device production
- Semiconductor manufacturing
- Biotechnology research
- Aerospace component assembly
Their controlled environments help maintain product quality and reliability while ensuring compliance with regulatory standards.

iso 7 vs. ISO 8 Comparison
| Feature | ISO 7 | ISO 8 |
|---|---|---|
| Max Particle Count | 352 particles/m³ | 3,520 particles/m³ |
| Air Change Rate | 30-60 ACH | 20-60 ACH |
| Typical Applications | Semiconductor, Pharma | Electronics, General Manufacturing |
| Gowning Requirements | Higher levels of gowning | Standard gowning |
Proper Usage of ISO 8 Cleanrooms
Preparation Before Entry
Personnel must undergo gowning procedures including cleanroom suits, gloves, masks, and shoe covers to minimize contamination risk.
Maintaining Cleanliness
Avoid unnecessary movement and limit material introduction. All equipment must be cleaned and sterilized before entering.
Continuous monitoring
Regular checks of temperature, humidity, and particulate levels are essential for maintaining compliance with standards.
