Within certain limits by the requirements of the standards for the production of various products, a cleanroom comes up with an innovative technical room in which the concentration of particles of pollutants is maintained.
While allowing other parameters to be controlled, such as temperature, humidity, and pressure, this is a room in which the counted concentration of aerosol particles is controlled, built, and used to minimize the intake, generation, and accumulation of particles inside the room.
The principle of building a “room-in-room” is the basis of architectural and construction decisions when creating a cleanroom.
By the space limited by the sealed elements of the enclosing structures, that’s how the working area of the cleanroom is formed.
At a certain level, which in turn depends on the requirements of the technological processes taking place in cleanrooms, and the cleanroom technology will always allow you to maintain air cleanliness.
Whole complexes of cleanrooms are needed in the conditions of pharmaceutical, nuclear, space, biological, optical production.
For the preparation and purification of air, they oftentimes include both the cleanroom themselves and the related systems.
Not only by the parameters of the building is itself, but also by the requirements of the technological processes and building codes, the scope of the entire project is determined.
That is why all the stages of design and construction of cleanrooms are standardized.
Before construction, a detailed plan of cleanrooms should be developed.
Where drawings of future cleanroom designs are created, further, after the preparation of all the necessary documents as far as the design phase comes into the context!
And, it is important to test before putting a cleanroom into operation.
The premises are put into operation if it is confirmed that the cleanroom is functioning by all standards and requirements, and the equipment meets the requirements of industrial, fire, and environmental safety standards.
Certification of a cleanroom is a procedure for checking the operating modes of a cleanroom, documenting the compliances of these modes with norms and rules, monitoring the actual value of the calculated concentration of particles in the air, as well as other parameters established by the standard.
Cleanroom Conditions That You Need To Know More About
- Built – The room is fully mounted. Engineering systems are connected. Equipment, materials, and personnel are absent.

- Equipped – The room is fully equipped with working equipment. The staff is absent.

- Operational – The room is functioning in an established manner. Personnel – Performs work functions.

- Project Qualification (DQ) – An examination aimed at confirmed the correctness of the implementation of project documentation.

- Certification in the built state (Installation Qualification, IQ) – Documentary evidence of the full compliance of the installed cleanroom design documentation.

- Performance Qualification (OQ) – Documentary evidence of the compliance of all construction and engineering systems with the approved project. Conclusion on the proper functioning of the installed equipment.

- Performance Qualification (PQ) – Documentary evidence of the normal operation of all systems. Full compliance with the required purity class, as well as general declared technological parameters.
The Main Operations Performed During The Cleanroom Test Are:
- Checking exhaust air and the volume of supply

- Air movement control between sections (zones)

- Checking the correct installation of high-performance filters

- Control of air leaks through building envelopes

- Air-flow control inside a cleanroom

- The concentration of aerosols and microorganism (if necessary)

- Additional tests
