The Importance of Validating your Cleanroom

Regular cleanroom validation can help detect and identify any harmful contamination sources, as well as assuring regulatory bodies and clients that your controlled environment continues to meet its ISO Class parameters.  In short, it ensures your critical process remains protected.

If a cleanroom does not have a current validation certificate to prove it meets the particle concentration limits set out in ISO 14644-1:2015 then it will not be compliant to ISO 14644-2:2015.

What is the risk to your business if you don’t regularly validate your Cleanroom?

Although guidance is in place for validating your controlled environment, the scope and frequency of your validations should be defined by your businesses individual risk assessment.  Intervals should be assigned in-line with each risk identified.  Failure to do so could result in high maintenance costs and loss of operational time.

How often should you validate your cleanroom?

To ensure that your cleanroom continues to perform efficiently and enhance your business process, it needs to be validated to prove it complies with ISO 14644-1:2015 - Classification of air cleanliness by particle concentration.

ISO 14644-2:2015 - Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration, recommends customers to complete risk assessments and monitoring plans to determine the frequency of testing and validation to their individual processes.

The above standard states the maximum time interval between airborne particle concentration testing of a cleanroom of ISO class 5 and below is 6 months and ISO class 6 and above is 12 months.

Filter integrity testing

Filter integrity and efficiency is vital.  If the filter is not working efficiently you run the risk of contamination entering your cleanroom, potentially impacting on your processes and product quality and, in turn, affecting your cleanroom classification.

Equipment using a HEPA or ULPA filter should be tested every time the equipment is moved to ensure no damage due to transportation has occurred and at regular intervals.

If your filter is not working efficiently you run the risk of contamination entering your cleanroom, potentially impacting on your processes and product quality and, in turn, affecting your cleanrooms classification. A DOP test can therefore reduce costly product recalls, saving money, time and preventing damage to your brand.
