Puhtausluokkat

Puhtausluokkat, a Finnish term, translates to "cleanliness classes" or "purity classes." In various contexts, it refers to systems or standards that categorize environments based on their level of cleanliness and freedom from contaminants. These classifications are crucial in industries where hygiene is paramount, such as pharmaceuticals, food production, and electronics manufacturing.

The purpose of puhtausluokkat is to define acceptable limits for airborne particles, microorganisms, and other potential contaminants within a specific area. Different classes are established, with stricter requirements for lower-numbered or higher-purity classes. For example, a pharmaceutical cleanroom designed for sterile drug manufacturing will have a much more stringent puhtausluokka than a general assembly area in an electronics factory.

The implementation of puhtausluokkat involves rigorous monitoring, control measures, and validation processes. This can include specialized ventilation systems, air filtration, strict gowning procedures for personnel, and regular environmental testing. Adherence to these classes ensures product quality, prevents contamination, and safeguards public health. Standards like ISO 14644 provide internationally recognized guidelines for cleanroom classification, which are often adapted or referenced when establishing puhtausluokkat within a facility.
