From Construction to Operation: A Guide to Cleanroom Commissioning, Qualification, and Validation


Cleanroom commissioning, qualifications, and validations are crucial processes in various industries such as pharmaceuticals, biotechnology, healthcare, electronics manufacturing, and semiconductor production, where maintaining controlled environments is essential. Here’s an overview of each process:

Cleanroom Commissioning:

Definition: Cleanroom commissioning refers to the process of ensuring that a cleanroom facility is built according to design specifications and is capable of meeting the required environmental conditions.

  • Design Review: Verify that the cleanroom design meets regulatory requirements and industry standards.
  • Construction Oversight: Supervise the construction process to ensure compliance with design specifications.
  • Installation and Testing of Systems: Install and test HVAC systems, filtration systems, monitoring systems, and other equipment to ensure they function properly.
  • Initial Cleanliness Testing: Conduct initial cleanliness testing to verify that the cleanroom meets cleanliness standards.
Cleanroom Qualification:

Definition: Cleanroom qualification involves demonstrating that a cleanroom facility consistently meets predefined criteria for cleanliness and environmental conditions.

  • Installation Qualification (IQ): Verify that equipment, instrumentation, and systems are installed correctly and meet design specifications.
  • Operational Qualification (OQ): Ensure that equipment and systems operate according to predetermined parameters and requirements.
  • Performance Qualification (PQ): Validate that the cleanroom operates consistently and meets cleanliness and environmental standards under dynamic conditions over a defined period.
Cleanroom Validation:

Definition: Cleanroom validation is the process of confirming that the cleanroom facility consistently produces the desired level of cleanliness and environmental conditions to meet regulatory requirements and product specifications.


  • Protocol Development: Develop validation protocols outlining the procedures and acceptance criteria for validation activities.
  • Execution of Validation Activities: Perform validation activities such as particle count testing, air velocity measurement, temperature and humidity monitoring, and microbial monitoring.
  • Data Analysis and Reporting: Analyze validation data to ensure compliance with predefined criteria and generate validation reports documenting the results.
  • Periodic Revalidation: Establish a schedule for periodic revalidation to ensure ongoing compliance with regulatory requirements and industry standards.

These processes are typically conducted by multidisciplinary teams consisting of engineers, validation specialists, quality assurance personnel, and other relevant stakeholders. Compliance with regulatory standards such as ISO 14644 (for cleanroom classification) and cGMP (current Good Manufacturing Practice) is essential throughout the commissioning, qualification, and validation processes.
