What equipment qualification means in GMP
Qualification is the documented evidence that equipment, utilities and systems are installed correctly, operate as intended and consistently produce results that meet specifications. In EU GMP, qualification is a prerequisite for any product manufactured for patient use.
For cannabis operations seeking EU GMP certification or supplying pharmaceutical-grade markets, qualification is not optional. Unqualified equipment cannot legally be used to manufacture a medicinal product under European pharmaceutical law.
Installation Qualification (IQ)
IQ confirms that equipment has been installed correctly and in accordance with manufacturer specifications, drawings and engineering requirements. It captures the physical installation — utilities connected, dimensions confirmed, safety systems in place, documentation received and reviewed.
IQ should be performed before the equipment is used for any production or testing purpose. The IQ protocol is approved before execution and the completed IQ report is reviewed and signed off before OQ begins.
Operational Qualification (OQ)
OQ confirms that the equipment operates as intended across its operating range. It tests the equipment functions — typically at minimum, maximum and nominal conditions — to demonstrate that the system behaves predictably and within defined acceptance criteria.
OQ is where many cannabis operations encounter difficulties. Acceptance criteria must be defined before execution, not after reviewing results. Criteria defined retrospectively are not considered valid under EU GMP.
Performance Qualification (PQ)
PQ demonstrates that the equipment consistently produces product or output that meets specification under routine operating conditions. Unlike IQ and OQ, PQ is performed using actual production materials and conditions. It is the closest test to real-world performance.
PQ requires a minimum number of successful, consecutive runs — the number is risk-based and should be justified in the validation master plan or qualification protocol.
Lifecycle thinking and requalification
Equipment qualification is not a one-time event. Under ICH Q8, Q9 and Q10, pharmaceutical quality systems are expected to manage qualification across the equipment lifecycle: initial qualification, ongoing monitoring, change control when modifications are made and periodic review to confirm the qualified state is maintained.
In cannabis manufacturing, change control is a common gap. Equipment modifications made without formal change control can invalidate the qualified state and require partial or full requalification.
