What Do IQ, OQ and PQ Mean for a Packaging Line?
Where a regulated quality system requires qualification, IQ confirms installation, OQ challenges operation and PQ demonstrates the approved process under defined routine conditions.
IQ, OQ and PQ provide different evidence and must be defined for the actual quality system
Installation qualification (IQ) confirms that equipment and supporting services are installed against approved information. Operational qualification (OQ) challenges defined functions and operating ranges. Performance qualification (PQ) demonstrates performance with approved materials, procedures and routine conditions where the user’s quality system requires it.
IQ, OQ and PQ are not alternative names for factory acceptance testing (FAT), site acceptance testing (SAT) or commissioning. Those activities can supply useful evidence, but the customer’s validation or qualification plan determines whether evidence is suitable, who approves it and what additional tests are required.
EU GMP Annex 15 describes lifecycle, risk-based principles for qualification and validation of facilities, equipment, utilities and processes used in medicinal-product manufacture. It also makes clear that the scope and extent should be based on a justified and documented risk assessment. Read EU GMP Annex 15.
| Stage | Question answered | Typical evidence categories |
|---|---|---|
| IQ | Is the approved equipment installed and documented correctly? | Identity, location, utilities, components, software versions, drawings, manuals, calibration status and installation checks. |
| OQ | Do functions, controls, alarms and operating limits behave as intended? | Operating modes, interlocks, alarms, recipes, access, challenge conditions, reject functions, recovery and data handling. |
| PQ | Does the qualified system perform consistently under the approved production process? | Approved materials, trained operators, procedures, routine environment, quality results, sampling plan and repeated production evidence. |
Start with the user requirement, risk assessment and validation strategy
Do not buy a generic document pack and assume it proves the installed packaging process.
Define the regulated boundary
Identify which equipment, utilities, software, records, inspection functions and interfaces affect product quality or controlled data.
Link every test to a requirement
Use requirement references and an approved protocol so results can be traced to the intended use and acceptance criteria.
Separate supplier and user responsibilities
The supplier can provide design, installation, functional and test evidence. The regulated manufacturer owns its validation strategy, approvals and final release.
Plan deviations and changes
Record unexpected results, assess impact, approve corrective work and decide which tests or documents must be repeated.
Qualification scope must be agreed, not assumed
Lancing can discuss machinery documentation, agreed tests and project evidence. Final IQ, OQ, PQ, process validation and regulatory acceptance depend on the customer’s product, intended use, quality system, risk assessment and competent approval.
Use FAT, SAT and commissioning evidence without confusing their purpose
Controlled supplier evidence can reduce duplication when the qualification plan accepts it and its conditions, instruments, records and approvals are suitable.
| Project activity | Useful evidence | Qualification limitation |
|---|---|---|
| Design review | Approved drawings, specifications, risk decisions, component lists and software architecture. | Approval of a design does not prove installation or operation. |
| FAT | Functional tests, sample handling, alarms, recipes, reject functions and documented deviations before dispatch. | The supplier environment may not reproduce installed utilities, retained equipment or routine production. |
| Commissioning | Connection checks, settings, interfaces, dry runs, product trials and initial fault resolution. | Commissioning establishes operation; it is not automatically an approved qualification protocol. |
| SAT | Installed functions, utilities, line interfaces, site materials, operators and agreed site acceptance criteria. | SAT scope may be commercial and narrower than the customer’s regulated qualification need. |
| Production qualification | Approved routine procedures, trained personnel, representative or worst-case products and recorded quality results. | Conditions and sampling must follow the customer’s approved validation approach. |
Questions buyers ask about packaging-line IQ, OQ and PQ
The correct answer depends on intended use and the customer’s quality system.
What is IQ for a packaging line?
IQ is documented confirmation that the approved packaging-line equipment, utilities, software and supporting records are installed as intended. The protocol should identify what is in scope, the approved references, the checks, acceptance criteria, instruments, results, deviations and approval route.
What is OQ for a packaging line?
OQ is documented testing of defined functions and operating conditions. It can challenge modes, controls, alarms, access, recipes, inspection, rejection, line states and operating ranges. The exact challenge set should be justified by the intended use and risk assessment rather than copied from another machine.
What is PQ for a packaging line?
PQ demonstrates that the qualified line performs consistently for its approved process under defined routine conditions. It commonly uses approved materials, trained operators, controlled procedures and a sampling plan. The manufacturer’s quality unit or authorised function determines the protocol and release decision.
Is FAT the same as OQ?
No. FAT is normally a supplier-site acceptance activity. OQ is a qualification stage performed under an approved validation framework. Some FAT evidence may support OQ when it is planned, traceable, suitably controlled and accepted by the customer, but the terms should not be treated as interchangeable.
Is SAT the same as PQ?
No. SAT confirms agreed installed and site-dependent acceptance conditions. PQ demonstrates performance for the approved routine process under the user’s qualification plan. A SAT run may contribute evidence, but it does not automatically fulfil PQ scope, repetition, sampling or approval requirements.
Who owns packaging-line qualification?
The regulated manufacturer owns its validation strategy, procedures, risk decisions and final approval. Suppliers and integrators can provide design information, documentation and agreed test execution. Responsibilities should be written into the URS, project scope, protocols and responsibility matrix before testing begins.
Information to discuss before quotation
- Intended use, product family and regulated quality-system context.
- Existing URS, validation plan and risk assessment.
- Required supplier documents and approval format.
- Software, data, user-access and audit-trail expectations.
- FAT, SAT, IQ and OQ boundaries and witness requirements.
- Samples, instruments, protocols, deviation handling and handover records.
Define the evidence package early
Share the intended line, qualification expectations and current procedures before the proposal is fixed. Lancing can then identify which machinery documents, tests and project records can be included and which responsibilities remain with the user.
