Installation Qualification (IQ) of Pharmaceutical Equipment
A practical guide to verifying that pharmaceutical equipment is installed as approved, documented correctly, and ready for operational qualification.
Quick answer: What is Installation Qualification?
Installation Qualification (IQ) is documented verification that equipment, utilities, instruments, and related components have been installed or modified according to approved drawings, specifications, and predefined criteria. It also confirms that key installation records—such as manuals, calibration evidence, material information, and maintenance requirements—are available and controlled. IQ establishes a reliable installed-state baseline before Operational Qualification (OQ).
What is Installation Qualification (IQ) of pharmaceutical equipment?
Installation Qualification is the documented check that the equipment as installed matches its approved design and is supported by the records needed for controlled use. Depending on the asset, IQ can cover the main machine, product-contact parts, instrumentation, control panels, connected pipework, utility connections, software or firmware identification, and associated documentation.
IQ answers the question: “Has the equipment and its relevant supporting systems been installed correctly and can the installed configuration be identified and maintained?” It does not, by itself, prove that the equipment operates across its full operating range or consistently performs the manufacturing process. Those are generally addressed through OQ and PQ.
For a new tablet press, for example, IQ may verify the asset identification, installation location, machine configuration, electrical and compressed-air connections, relevant instrumentation, calibration status, manuals, drawings, and maintenance information. It would not normally use IQ alone to demonstrate tablet weight control across the press’s operating range.
Regulatory and GMP context for equipment IQ
EU GMP Annex 15 states that IQ should be performed for equipment, facilities, utilities, and systems. Its examples include checking installation of components, instruments, equipment, pipework, and services against engineering drawings and specifications; verifying installation against predefined criteria; collecting supplier operating and maintenance instructions; checking instrument calibration; and verifying construction materials. The Annex also describes IQ as part of qualification across the lifecycle. See EU GMP Annex 15.
In the United States, FDA’s drug CGMP framework requires equipment to be suitable for its intended operation and designed to facilitate cleaning and maintenance. Product-contact surfaces must not adversely affect product quality, and automatic, mechanical, or electronic equipment must be appropriately controlled and checked. FDA’s equipment Q&A discusses these expectations and references 21 CFR 211.63, 211.65, 211.67, and 211.68. Read the FDA equipment Q&A.
These regulations and guidance do not create one universal IQ checklist for every asset. The manufacturer defines an appropriate, documented approach based on applicable requirements, intended use, equipment complexity, and quality risk. ICH Q9(R1) states that quality risk evaluation should be scientifically grounded and that the level of effort, formality, and documentation should be proportionate to risk. See ICH Q9(R1).
Define IQ scope, equipment boundaries, and interfaces
Before drafting the protocol, define what is included and where the equipment boundary ends. A skid-mounted system may include a vessel, pump, valves, local instruments, control panel, and software. It may also connect to site utilities, a building management system, a data historian, or a central automation platform. If these interfaces are not described, installation checks can overlook important connections or duplicate work across system owners.
Use the approved URS, Design Qualification (DQ), purchase specification, approved drawings, supplier documentation, and project risk assessment to define the baseline. Make sure the IQ protocol identifies equipment tags, subassemblies, instruments, utilities, and any excluded items with a rationale.
When equipment is computerized or has programmable control, the IQ should capture the installed hardware and software configuration needed to identify the system. Detailed access, electronic records, audit trail, and functional testing belongs in the applicable computerized-system lifecycle and/or OQ, not automatically in IQ. See Computerized System Validation.
IQ prerequisites and installation readiness
Starting IQ before the equipment is ready can create a pile of avoidable deviations. Before execution, confirm the following as applicable:
- The equipment is received, identified, and in a condition suitable for inspection.
- Approved URS, design records, installation drawings, specifications, and protocol revisions are available.
- The equipment scope, tag numbers, critical components, and utility interfaces are defined.
- Installation and commissioning activities that could affect IQ results are complete or have a documented interface plan.
- Required utilities are available and their qualification or release status is known.
- Measuring devices used to perform IQ checks are calibrated and suitable for the measurement.
- Supplier documents, material certificates, manuals, and maintenance recommendations have been requested and are traceable.
- Personnel executing and reviewing the checks are trained for their assigned responsibilities.
- Safety controls, permits, and isolation requirements are in place for inspections and checks.
Not every IQ needs every prerequisite. The protocol should identify which are relevant and how readiness is evidenced. If commissioning and qualification run in parallel, clearly separate commissioning records from approved qualification evidence and define how any commissioning change is assessed.
How to perform Installation Qualification: step-by-step
Approve the protocol and confirm the baseline
List the equipment scope, location, tag and serial numbers, approved design references, roles, prerequisites, test methods, acceptance criteria, deviation process, and required approvals. Reference the current approved URS and DQ package.
Verify equipment identity and physical condition
Compare nameplate details, manufacturer, model, serial number, asset tag, configuration, and supplied accessories with the purchase and design records. Note visible damage, missing parts, or unapproved substitutions before proceeding.
Inspect installation against drawings and specifications
Check location, orientation, mounting, anchoring, clearances, guards, pipework, cabling, connections, and component arrangement against approved documents and predefined criteria. Record drawing numbers and revisions used during the check.
Verify utilities and interfaces
Confirm the required utility connections are present, correctly identified, and connected according to approved design. Verify interface boundaries with qualified site systems or other equipment. Do not infer utility quality from a connection check alone; use the relevant utility qualification records.
Check instruments and calibration status
Confirm critical instruments are identified, installed in the intended location and orientation, and listed in the instrument register. Verify calibration status, range, units, and traceable certificates according to site procedures. Document instruments that require calibration before OQ or use.
Verify construction materials and product-contact components
Review material certificates, component lists, labels, or other approved evidence for product-contact parts and critical piping where required by the design. Confirm supplier documentation matches the installed components and the approved specification.
Collect controlled supplier and maintenance documents
Record receipt and revision of operating instructions, maintenance requirements, spare-parts lists, drawings, manuals, certificates, and recommended calibration details. Identify missing documents and assign closure actions.
Capture computerized-system configuration where applicable
Document relevant hardware identifiers, software/firmware version, controller or HMI identity, network connections, and configuration references needed to establish the installed baseline. Perform functional challenges under the appropriate approved test stage.
Record discrepancies and assess impact
Document each failed or unclear check as required by the approved procedure. Assess whether it affects safety, product quality, data, downstream qualification, or readiness to use. Resolve or formally disposition the finding before IQ closure.
Prepare the IQ report and release decision
Summarize results against acceptance criteria, list evidence references, explain deviations and open items, and recommend whether the installed equipment may progress to OQ. Obtain approval from designated personnel before moving to the next stage.
Pharmaceutical equipment IQ checklist
This checklist is a planning aid, not a universal regulatory form. Adapt it to the equipment, approved design, and site risk assessment.
| IQ area | Typical verification | Example evidence |
|---|---|---|
| Identification | Manufacturer, model, serial number, asset tag, configuration, and location match the approved records. | Nameplate record; asset register; photograph if permitted |
| Installation | Position, orientation, supports, clearances, guards, and assembly match approved drawings. | Marked-up drawing; installation checklist; inspection record |
| Utilities | Connections, sizes, labels, and interfaces match the design; utility release status is referenced. | Utility connection check; P&ID; utility qualification reference |
| Instrumentation | Required instruments are installed, tagged, correctly ranged, and calibrated as defined. | Instrument list; calibration certificate; tag check |
| Materials | Critical construction and product-contact materials match approved specifications. | Material certificates; vendor records; identification checks |
| Documentation | Current manuals, drawings, operating instructions, maintenance information, and certificates are received. | Document index; supplier handover package |
| Control system baseline | Relevant hardware and software versions and configuration identifiers are captured. | Version record; configuration backup reference; system inventory |
| Safety and access | Installation permits safe operation, inspection, cleaning, and maintenance access as designed. | Safety inspection; access review; handover record |
| Deviation and closure | Findings are recorded, assessed, corrected, or formally dispositioned. | Deviation/CAPA records; closure evidence |
IQ acceptance criteria and deviation handling
Acceptance criteria should be written before execution and be objective. Examples include: the installed tag and serial number match the approved equipment list; the measured or observed installation condition meets a stated drawing or specification; required instruments are present and have acceptable calibration status; specified documents have been received; and no unresolved critical installation discrepancy prevents safe progression to OQ.
There is no single numeric IQ acceptance limit that applies to all equipment. Use approved drawings, supplier specifications, user requirements, engineering standards, calibration procedures, and site-defined criteria as the basis. If an acceptance criterion must change, handle it through controlled, scientifically justified revision rather than editing a result after the fact.
For a failed check, document what was expected, what was observed, evidence collected, potential impact, correction or rationale, retest results, and approval. A critical open item may block OQ or equipment release. Lower-risk open items may only remain open if site procedures allow it and there is an approved impact assessment, owner, deadline, and appropriate restriction on use.
Use the site's CAPA process when the issue warrants systemic corrective or preventive action. Any change to the installed configuration after IQ should be assessed through change control and may require partial or full requalification.
IQ protocol, records, and final report
A complete IQ package normally includes:
- Approved IQ protocol with scope, responsibilities, prerequisites, procedures, and predefined acceptance criteria.
- Equipment identification and boundary list, including relevant instruments, accessories, and utility interfaces.
- Approved drawings, specifications, URS, and design references used for comparison.
- Completed checklists and objective evidence, including calibration and material documentation as applicable.
- Supplier manuals, operating instructions, maintenance requirements, and handover documents.
- Deviations, change records, corrective actions, retests, and approved impact assessments.
- IQ summary report with results, open items, conclusion, and formal authorization to progress.
Maintain records in a way that shows who performed and reviewed each activity, when it occurred, what equipment and document revision were checked, and where supporting evidence is stored. This supports ALCOA+ data-integrity expectations and helps future maintenance, investigation, and periodic review.
Common IQ mistakes and how to avoid them
- Using a generic checklist without equipment-specific criteria: tailor checks to the approved design, system boundary, and risks.
- Starting before installation is stable: define how commissioning changes and incomplete work will be controlled during qualification.
- Confusing IQ with OQ: use IQ to verify installation and baseline records; reserve operating-range and functional challenges for OQ unless an approved integrated protocol justifies combined testing.
- Checking a utility connection but not its release status: reference the qualified utility evidence and check the equipment interface separately.
- Accepting missing supplier records informally: list required deliverables, record gaps, and close them under controlled action.
- Recording only “pass” without evidence: identify the document, observation, measurement, certificate, or record that supports the result.
- Ignoring changes made after testing: assess any relocation, instrument replacement, software change, or utility modification for requalification impact.
- Allowing unclear open items at closure: classify their quality impact, define restrictions if necessary, assign ownership, and obtain required approval.
Risk-based qualification does not mean omitting checks without rationale. It means concentrating effort on features that matter to intended use, product quality, safety, data, and continued control.
Moving from IQ to OQ and PQ
Once IQ is complete and approved, OQ can challenge the equipment’s functions, controls, alarms, interlocks, operating ranges, and relevant worst-case conditions. After successful IQ and OQ, PQ can show that the equipment and connected systems perform effectively and reproducibly under intended process conditions. Annex 15 describes these stages and allows an integrated IOQ approach where justified by equipment complexity.
For full lifecycle context, see Equipment Validation in Pharmaceuticals, the related OQ guide, and the PQ guide. Equipment that affects a validated process should also be considered within the site’s Process Validation strategy.
Frequently asked questions
1. What is Installation Qualification (IQ) in pharma?
IQ is documented verification that equipment and its relevant components are installed according to approved drawings, specifications, and predefined criteria, with required installation records and calibration evidence available.
2. What is the purpose of equipment IQ?
IQ establishes that the equipment’s installed configuration is correctly identified, matches the approved design, and has the documentation and supporting controls needed before operational testing and use.
3. What is checked during pharmaceutical equipment IQ?
Typical checks include equipment identity, location, assembly, connections, utilities, instruments, calibration status, construction materials, manuals, maintenance information, drawings, and relevant software or hardware version details.
4. Is IQ required by GMP regulations?
EU GMP Annex 15 states that IQ should be performed on equipment, facilities, utilities, and systems. Other regulatory frameworks may specify equipment-control outcomes rather than one universal IQ format. Follow applicable regulations and the site’s approved quality system.
5. What is the difference between IQ and OQ?
IQ verifies that equipment is installed as approved. OQ verifies that it operates as intended across defined ranges and conditions. IQ normally precedes OQ, though an approved combined IOQ approach may be suitable in some cases.
6. Does IQ include calibration?
IQ commonly verifies that required instruments are installed and their calibration status is acceptable under site procedures. Calibration itself may be performed under a separate controlled procedure, with its evidence referenced in the IQ record.
7. Can FAT replace IQ?
No. FAT may provide evidence for selected checks when its scope and results are reviewed and its applicability is justified. IQ still needs to address installation at the site, site utilities, transport or installation impacts, and other site-specific requirements.
8. What documents are needed for IQ?
Common records include the approved protocol, URS and design references, current drawings, equipment identification, completed installation checks, calibration evidence, material records, supplier manuals, maintenance instructions, deviations, and the final report.
9. What happens if equipment fails an IQ check?
Record the discrepancy, assess its impact, correct or formally disposition the issue, and document any retest and approval. Critical unresolved items may prevent progression to OQ or release for use, according to site procedures.
10. When is requalification required after IQ?
Assess changes, relocation, major repair, utility modification, instrument replacement, or control-system updates through formal change control. The impact assessment determines whether partial or full requalification is appropriate.
Conclusion
Installation Qualification provides documented evidence that pharmaceutical equipment is installed according to its approved design and is supported by the records needed for controlled operation. A clear system boundary, equipment-specific criteria, traceable checks, and documented deviation handling make IQ more than a checklist—it becomes the dependable installed-state baseline for OQ, PQ, maintenance, and future change control.
