Understanding ISO Clean Room Classification: Read This in 60 Seconds: Your Guide to Clean Room Standards

ISO clean room classification is crucial for industries that require sterile environments, such as pharmaceuticals, aerospace, and electronics. Understanding these classifications helps ensure that your clean room meets the necessary standards to minimize contamination. The classifications are based on the number and size of particles permitted in the air, categorized by ISO 14644-1 standards.

What is ISO Clean Room Classification?

The ISO clean room classification system categorizes clean rooms based on the maximum allowable concentration of airborne particles. These classifications range from ISO Class 1, which allows the least number of particles, to ISO Class 9, which permits higher particle counts. The goal of this system is to maintain a controlled environment that minimizes the risk of contamination.

Key Classifications Explained

ISO Class 1

This is the cleanest classification, allowing only 12 particles per cubic meter of air, with a size of 0.1 µm or larger. It is typically used in semiconductor manufacturing and critical pharmaceutical applications.

ISO Class 5

ISO Class 5 clean rooms allow for a maximum of 3,520 particles per cubic meter, with a size of 0.5 µm or larger. This class is commonly used for clean bench environments and some medical device manufacturing.

ISO Class 9

ISO Class 9 is the least stringent, permitting up to 35,200,000 particles per cubic meter, which is suitable for areas where high cleanliness is not critical.

Importance of Clean Room Classification

Maintaining the appropriate clean room classification is essential for product quality and compliance with industry regulations. Regular monitoring of air quality and particle counts is necessary to ensure that the clean room operates within its classified parameters. Failure to adhere to these standards can lead to product contamination, recalls, and significant financial losses.

Conclusion

In summary, ISO clean room classification is vital for industries that handle sensitive products. Understanding these classifications helps ensure that clean rooms meet the necessary requirements for maintaining a controlled environment.
