Lifecycle Qualification Strategies for Modern Cleanrooms (DQ–IQ–OQ–PQ)

By Kjeld Lund 30 January, 2026 • January 29, 2026
Lifecycle Qualification Strategies for Modern Cleanrooms (DQ–IQ–OQ–PQ) 1. Introduction Lifecycle qualification is a foundational framework for ensuring that modern cleanrooms consistently meet the performance, compliance, and product-protection requirements defined by ISO 14644 , GMP Annex 1 , and related regulatory expectations. The DQ–IQ–OQ–PQ sequence provides a structured, evidence-driven method to verify that a cleanroom is designed correctly, installed correctly, operating correctly, and performing consistently under real process conditions. This article outlines practical, engineering-grounded lifecycle qualification strategies suitable for new cleanroom facilities, major retrofits, and ongoing performance lifecycle management. 2. Design Qualification (DQ) Design Qualification establishes that the cleanroom design—down to the HVAC architecture, building envelope, process layout, and control strategies—meets the intended functional, regulatory, and risk-reduction requirements. DQ must be fully documented and approved prior to procurement or construction. Key Objectives Demonstrate alignment with user requirements (URS), regulatory standards, and contamination-control risk assessments. Validate the design basis for airflow volume, pressure regime, filtration efficiency, heat loads, and classification goals. Confirm that materials, finishes, and mechanical/electrical systems support cleanability, durability, and cleanroom compatibility. Core Activities URS Development: Defines required cleanliness class (e.g., ISO 7/8 rooms leading to ISO 5 zones), environmental parameters, process flows, and gowning strategy. Basis of Design (BOD) Review: Verifies engineering assumptions including supply air volume, terminal HEPA load, air change rate targets, and pressure cascade. Design Risk Assessment: Evaluates contamination pathways, personnel/material movement, and failure modes (e.g., loss of differential pressure). Drawings and Specification Review: Architectural drawings, HVAC schematics, control diagrams, and finish schedules are checked against URS and applicable standards. DQ Acceptance Criteria All functional requirements traceable to the URS. Design conforms to ISO 14644 requirements, GMP zoning concepts, and classified-area pressure cascade norms. Design risks identified and mitigated with engineering or procedural controls. 3. Installation Qualification (IQ) Installation Qualification verifies that the cleanroom and its systems were installed according to approved design documentation and equipment specifications. IQ is typically executed after construction is complete but prior to HVAC balancing and environmental verification. Key Objectives Confirm correct installation of architectural elements, HVAC components, filtration assemblies, electrical systems, and monitoring devices. Verify that materials and finishes meet certification requirements (e.g., low-VOC, non-shedding, GMP-compatible). Document all utilities, equipment IDs, calibration statuses, and as-built conditions. Core Activities Component Verification: HEPA/ULPA filters, fan filter units (FFUs), terminal housings, ductwork, dampers, valves, and sensors must match approved specifications. Material and Finish Inspection: Wall panels, flooring, doors, pass-throughs, and sealants are checked for fit, compatibility, cleanability, and integrity. As-Built Documentation: Includes redlined drawings, HVAC equipment lists, control sequences, and wiring diagrams. Calibration and Utilities Check: Differential pressure sensors, temperature/humidity probes, and airflow measurement devices are installed, tagged, and calibrated. IQ Acceptance Criteria All equipment installed per manufacturer recommendations and design documents. All sensors and instruments calibrated with traceability. As-built documentation complete and approved. 4. Operational Qualification (OQ) Operational Qualification demonstrates that the cleanroom and its supporting HVAC/control systems operate as designed across the full range of expected environmental and operating conditions. OQ is executed after HVAC commissioning and initial balancing but before introducing process equipment or personnel workflows. Key Objectives Confirm the HVAC system achieves and maintains the required environmental conditions (classification, pressure, temperature, humidity). Demonstrate correct operation of interlocks, alarms, monitoring systems, and control loops. Verify that control logic supports contamination-control requirements, including recovery and cascade stability. Core Activities Airflow and Pressure Verification: Measurement of supply volume, extract volume, and differential pressures between adjacent zones under at-rest conditions. HEPA Integrity Testing: Leak testing using ISO 14644-3 compliant methods (e.g., PAO/DEHS aerosol challenge). Particle Classification Testing: Conduct at-rest classification tests per ISO 14644-1 to confirm compliance with specified cleanroom class. Recovery Testing: Demonstrate the room’s ability to return to classification levels after a particle challenge or simulated disturbance. Alarm and Interlock Testing: Validation of door interlocks, pressure-loss alarms, temperature/humidity deviations, and exhaust/supply failures. Environmental Stability Study: Trending temperature, humidity, and pressure over time to ensure steady-state performance. OQ Acceptance Criteria All environmental parameters meet specified limits under at-rest conditions. All alarms/interlocks operate predictably and within defined tolerances. HEPA filters pass integrity tests with no leaks above allowed limits. Particle counts comply with the ISO class designation. 5. Performance Qualification (PQ) Performance Qualification confirms that the cleanroom performs as required under normal operational conditions, including personnel activity, equipment operation, and process workflows. PQ represents the final verification stage before routine production or regulated use. Key Objectives Validate real-world performance including personnel-generated loads, process equipment heat loads, and operational contamination sources. Demonstrate environmental control and consistency during typical and peak operational states. Establish baseline performance data for future ongoing monitoring. Core Activities Dynamic Classification Testing: Particle sampling during typical operations with personnel, processes, and equipment running. Microbial Monitoring: Viable air and surface sampling following GMP Annex 1 expectations. Temperature/Humidity/Pressure Trending: Confirmation that environmental parameters remain stable during active operations. Process Simulation (Media Fill or Surrogate Operations): For aseptic processes, PQ may include media fills or other simulation protocols. Workflow Verification: Assessment of gowning, personnel behavior, and material transfer methods to ensure contamination control integrity. PQ Acceptance Criteria Cleanroom meets required ISO class under operational conditions (where required by process). Microbial contamination levels remain within specified action and alert limits. Operational conditions do not compromise the pressure cascade or airflow patterns. All critical process simulations meet acceptance criteria. 6. Documentation Structure and Traceability A robust documentation package ensures regulatory compliance and facilitates future audits and requalification. Each lifecycle stage must include: Qualification protocols (DQ/IQ/OQ/PQ) with clearly defined acceptance criteria. Traceability matrices linking URS → DQ → IQ/OQ/PQ tests. Calibration records, commissioning reports, and as-built drawings. Deviations, corrective actions, and risk assessments. A final qualification summary report consolidating results and confirming readiness. 7. Integration With ISO 14644 and GMP Annex 1 Modern cleanroom qualification strategies must continuously reflect international standards and regulatory updates. ISO 14644 Part 1: Air cleanliness classification by particle concentration. Part 2: Monitoring requirements for demonstrating continued compliance. Part 3: Test methods for cleanroom performance (airflow, recovery, HEPA integrity). Part 4: Design, construction, and start-up best practices. Part 16: Energy efficiency considerations. GMP Annex 1 adds requirements for: Contamination Control Strategy (CCS). Formal risk management throughout the cleanroom lifecycle. Demonstrable environmental control during sterile operations. Expected performance and monitoring frequencies for classified areas. Qualification strategies must ensure that the DQ–IQ–OQ–PQ lifecycle aligns with every relevant element of the CCS, including airflow design, cleaning effectiveness, gowning, and monitoring programs. 8. Requalification and Ongoing Lifecycle Management Qualification does not end with PQ. Cleanrooms require periodic requalification, especially HEPA integrity, airflow verification, and environmental monitoring performance assessments. Typical requalification intervals: HEPA integrity: annually (or more often for high-risk areas). Airflow/pressure/temperature/humidity: semiannual to annual, depending on risk. ISO classification tests: typically annual for high-grade areas; up to biennial for lower-risk rooms, based on documented risk justification. Changes in configuration, HVAC equipment, control logic, or process flows should trigger change control and potentially partial requalification. 9. Conclusion Effective lifecycle qualification using the DQ–IQ–OQ–PQ framework is fundamental for ensuring that modern cleanrooms are engineered, constructed, and operated to meet rigorous contamination-control requirements. A disciplined approach grounded in ISO 14644, GMP Annex 1, and established engineering practice produces cleanrooms that operate with reliability, safety, and regulatory confidence. By maintaining robust documentation, integrating risk management, and committing to ongoing monitoring and requalification, facility owners and operators can ensure long-term cleanroom performance and compliance.
