How are Clean Rooms classified? On the basis of which parameters? How often do they need to be retrained?

Cleanrooms are quality control environments that are used in many industries, including pharmaceuticals, to ensure the purity and sterility of products. Cleanrooms are classified according to environmental requirements such as particle concentration, pressure, humidity, temperature, and light.

Classify a clean room

Clean rooms are identified according to their class: The degree of environmental purity that is maintained inside the room. The class ranges from ISO 1 (cleanest) to ISO 9 (dirtiest).

Cleanrooms need to be redeveloped regularly to ensure they are still able to meet environmental requirements. The frequency of these renovations depends on the class of the room, the use that is made of it and the degree of purity required.

Clean rooms: the legislation

In general, ISO class 5 cleanrooms are redeveloped at least once a year, while dirtier cleanrooms are redeveloped every 2-3 years. However, these are general guidelines, and the frequency of retraining may vary based on the specific needs of each company.

Regulations governing cleanrooms include ISO 14644 for cleanroom qualification and classification, as well as the Food and Drug Administration (FDA) regulation for the manufacture of pharmaceutical products. These regulations define the environmental requirements for cleanrooms and establish the criteria for their classification and requalification.

Cleanrooms are facilities that must maintain a particular environmental purity to ensure the quality of the products that are processed within them. These environments are classified according to parameters such as particle concentration, pressure, humidity, temperature, and light. The frequency of requalification depends on the class and the use of the room. The regulations governing cleanrooms are ISO 14644 and FDA.
