The international standards for cleanroom operation (ISO 14 644-1) have been updated. Philippe Duhem, a Senior Consultant with Intertek, examines the changes
Cleanroom operation impacts many high tech industries including pharmaceutical manufacturing, but did you know that cleanroom international standards have been recently updated?
Cleanrooms are classified by their air quality, and the class of a cleanroom is determined by measuring the number of particles in one cubic foot, and defining their limits. Standards exist for classification and testing as covered in the ISO 14 644-1 standards. After 10 years of effort by regulatory bodies and industry authorities the revision has now been published, bringing improved scientific rigor to the testing requirements, monitoring and data handling.
The main change to ISO 14 644-1 is the introduction of a model based on hypergeometric law.
The practical consequences for users are:
An additional, significant change is relevant to the particulate concentration limits for 5μ particles in ISO5 classes. These changes have a regulatory impact for the healthcare product industry.
With these changes in mind, users should now assess and update their practices, their atmosphere classification documentation and train their employees to this new standard.
