Clean rooms are used in pharmaceuticals, electronics, medicine and the space industry. Choosing the right materials is critical to maintaining the required cleanliness class.
Clean Room Classification According to ISO 14644
The international standard ISO 14644-1 classifies clean rooms by the number of particles in the air:
| ISO Class | Particles ≥0.5 µm/m³ | Application |
|---|---|---|
| ISO 1 | 10 | Nanotechnology |
| ISO 5 | 3,520 | Microelectronics |
| ISO 6 | 35,200 | Pharmaceuticals |
| ISO 7 | 352,000 | Operating theatres |
| ISO 8 | 3,520,000 | Laboratories |
Material Requirements
Materials for clean rooms must:
- Not emit particles — low dust generation
- Be smooth — no pores or cracks
- Withstand disinfection — chemical resistance
- Have antistatic properties — prevent particle attraction
- Be easy to clean — minimal cleaning effort
