ISO Class 5 Cleanroom Information
Information on ISO 14644-1:2015 class 5 Cleanroom Classification.
- Federal Standard 209E equivalent: Class 100 Cleanroom
- EU GMP: A/B
- Air changes per hour required: 240-480
- For ISO Class 5 cleanrooms, organisations typically measure micron sizes 0.5µ and 0.3µ, with GMP A/B also looking at 5.0µ.
- See the maximum allowable concentrations by cleanroom class on our cleanroom classifications page.
Considerations for ISO Class 5 Cleanrooms
As ISO Class 5 cleanrooms are at the more critical end of the class spectrum, they require a greater level of filtration to achieve the level of cleanliness.
Ultra Low Penetration Air (ULPA) Filtration is 99.9995% efficient at 0.12 micron and should be considered when looking to achieve ISO class 5.
Hardwall and monobloc cleanroom constructions are most effective at achieving the environment required for ISO class 5.
If organisations are working towards GMP grades, monobloc is the most effective solution, as it can accommodate required features such as interlocked doors and coved floors.
See our case studies for more information.
