What Does Cleanroom IQ/OQ/PQ Mean?
Cleanroom qualification is the structured process used to prove that a cleanroom and its supporting systems are suitable for intended use. The three most recognized stages are IQ, OQ and PQ.
In practice, these stages are not just paperwork milestones. They form the evidence chain that links design intent, installation status, operational controls and routine performance. Without that chain, a cleanroom may appear functional but remain weak from a GMP or audit perspective.
IQ = 設置資格
- システムが正しくインストールされたことを確認します
- Checks drawings, materials and components
- Verifies utilities, labeling and documentation
OQ = 運用資格
- 定義された動作制限の下でクリーンルームをテストします
- Verifies alarms, airflow, pressure, recovery and controls
- システムが意図したとおりに動作することを示します
PQ = パフォーマンス資格
- 一貫した現実世界のパフォーマンスを実証
- 認定を実際のプロセス条件にリンク
- 日常的な生産または運用の準備をサポート
なぜそれが重要なのか
- GMP準拠の証拠を構築する
- 汚染管理の不確実性を軽減
- 監査の防御性と変更管理を向上します
クリーンルーム認定が GMP 準拠に重要な理由
A cleanroom is not qualified simply because it was built according to specification. It must be shown, with documented evidence, to operate and perform in a controlled, repeatable way. This is especially important in regulated environments where contamination risk, process consistency and data integrity all matter.
Qualification also protects the business side of operations. A weak validation framework can delay product release, increase deviation investigations, create repeated rework and undermine procurement decisions. A strong qualification strategy helps standardize equipment selection, SOP execution, environmental monitoring and cleaning system design.

Installation Qualification: Proving the Cleanroom Was Installed Correctly
IQ is the stage where the team confirms the cleanroom and its associated systems match approved design requirements. This includes room construction elements, utilities, HVAC components, HEPA or ULPA filtration setup, instruments, labeling, equipment lists, approved materials and document traceability.
Typical IQ Scope Includes
Design and Document Review
Approved drawings, specifications, equipment manuals and material certificates should match the installed condition.
Component Verification
Confirm critical components such as air handling units, filters, pressure gauges, doors, pass-throughs and monitoring devices are correctly installed.
Utility and Service Confirmation
必要な電気、圧縮空気、水、ガス、または制御インターフェースが正しく接続され、識別されていることを検証します。
校正および識別ステータス
動作テストを開始する前に、校正が必要な機器が特定され、管理されていることを確認します。
IQ is often undervalued, but weak IQ creates downstream failures in OQ and PQ. If the installed condition is not documented properly, later performance results become harder to interpret and defend.
運用資格: クリーンルームが定義された制限内で動作することを検証する
OQ confirms the cleanroom functions as intended under controlled operating conditions. This is where teams test alarms, airflow behavior, pressure differentials, temperature and humidity ranges, air change performance, recovery and other operating parameters.
The purpose of OQ is not merely to collect numbers. It is to prove that control systems, room behavior and operating limits are defined, understood and repeatable.
Common OQ Test Areas
- 気流速度と気流の可視化
- 差圧検証
- 温度と湿度のマッピング
- アラームチャレンジテストと応答検証
- 動作障害後の復帰時間
- 環境モニタリング戦略の調整
OQ はお客様と密接に関係している必要があります。 リスクベースのクリーンルーム環境モニタリング戦略, because routine monitoring logic becomes stronger when it is built on verified operational behavior rather than assumption.
Performance Qualification: Demonstrating Reliable Real-World Performance
PQ is the stage where the team proves the cleanroom can consistently support intended use during routine operation. Unlike IQ and OQ, which are more structured around design and system limits, PQ focuses on actual operating performance, including personnel, workflows, cleaning practices, environmental monitoring trends and process interaction.
In many regulated facilities, PQ is where the cleanroom becomes meaningful from a compliance standpoint. It shows that the room does not just operate in theory, but performs reliably in the presence of people, materials, interventions and routine demand.
PQ は通常考慮します
- 日常的な環境モニタリングのパフォーマンス
- オペレーターのガウンと行動制御
- 洗浄と消毒の効果
- 一般的な生産負荷またはプロセス負荷
- 長期にわたる傾向の一貫性
- 逸脱と逸脱への対応の成熟度
PQ は自然に次のようにリンクします クリーンルーム清掃SOP、 アラートおよびエクスカーション対応ワークフロー, and GMP監査の準備.

The table below helps teams quickly separate what belongs in each phase. This is useful for protocol writing, project planning and avoiding the common mistake of mixing installation evidence with routine performance evidence.
| 予選ステージ | 主な目的 | 典型的な証拠 | 弱い場合の重要なリスク |
|---|---|---|---|
| IQ | 正しくインストールされていることを確認する | 図面、機器リスト、証明書、ユーティリティチェック、ラベル表示、校正ステータス | その後の結果は信頼したり擁護したりするのが難しい場合があります |
| OQ | 定義された制限内で正しい動作を検証する | Airflow, pressure, alarm, recovery, temperature, humidity and control challenge data | 運用状況はまだよくわかっていない |
| PQ | 信頼できる日常パフォーマンスを実証 | Trend data, workflow evidence, EM outcomes, cleaning effectiveness and ongoing consistency | 現実世界のコンプライアンスリスクは、逸脱が発生するまで隠蔽されたままです |
Cleanroom IQ/OQ/PQ Documentation Pack
A complete cleanroom qualification file should allow an auditor to understand what was installed, how it was tested, what acceptance criteria were used and whether the cleanroom can support routine operation.
Approved Qualification Plan
Defines scope, responsibilities, acceptance criteria and execution sequence.
IQ Protocol and Report
Confirms installation, utilities, components, drawings, manuals and calibration status.
OQ Protocol and Report
Documents operational tests such as airflow, pressure, alarms, recovery and environmental controls.
PQ Protocol and Report
Demonstrates routine performance using environmental monitoring, workflow and cleaning evidence.

Records qualification failures, investigations, corrective actions and final approval decisions.
Final Qualification Summary
Summarizes results, unresolved risks, approvals and readiness for routine use.
資格と洗浄システムおよび消耗品の選択との関係
Qualification does not stop at air handling and room classification. In actual GMP operation, routine performance is shaped by details: how operators gown, how surfaces are cleaned, which mop systems are used, whether consumables are traceable and whether SOP execution is consistent.
This is where procurement and contamination-control choices become validation-relevant. A cleanroom may pass formal tests, but still struggle in PQ or ongoing monitoring if routine cleaning materials generate lint, leave residues or lack documentation support.

- 低リントのクリーンルーム対応構造
- 材料の一貫性とロット管理
- 必要に応じて無菌または滅菌ルート

Common IQ/OQ/PQ Qualification Mistakes
1. Treating IQ, OQ and PQ as Paperwork Only
認定を文書化の練習としてのみ行う場合、実際の運用上のリスクは、逸脱や監査によって暴露されるまで隠されたままになります。
2. Mixing Stage Objectives
チームは多くの場合、OQ 中の日常的なパフォーマンスを証明したり、弱い IQ を補うために PQ データを使用したりしようとします。各ステージでは異なる質問に答える必要があります。
3. Ignoring Environmental Monitoring Logic
監視場所とアラート/アクション ロジックが実際の部屋の動作とリスクに関連付けられていない場合、認定は非常に弱くなります。
4. Overlooking Cleaning and Operator Behavior
PQ is not only about equipment. It must reflect how the room performs with people, interventions, materials and routine cleaning execution.
5. Weak Audit Traceability
If protocols, raw data, deviations, approvals and SOP references are not linked clearly, qualification can become difficult to defend during inspection.

よくある質問
What is the difference between IQ, OQ and PQ in cleanroom qualification?
IQ verifies correct installation, OQ verifies correct operation within predefined limits, and PQ demonstrates reliable performance during real routine use.
Why is IQ/OQ/PQ important for GMP cleanrooms?
IQ/OQ/PQ provides documented evidence that the cleanroom is installed correctly, operates properly and consistently supports intended use, which is essential for GMP compliance, contamination control and audit readiness.
クリーンルームの資格には環境モニタリングと清掃が含まれますか?
Yes. During OQ and PQ, environmental monitoring strategy, operator behavior, gowning control and cleaning effectiveness are all relevant to proving controlled routine performance.
Can a cleanroom pass IQ and OQ but still fail PQ?
Yes. A cleanroom may be installed correctly and operate within technical limits, yet still underperform in routine use because of workflow issues, poor cleaning execution, operator interventions or unstable environmental monitoring trends.
What documents are usually needed for cleanroom IQ/OQ/PQ?
Typical documents include approved protocols, drawings, equipment lists, calibration records, test results, deviation reports, environmental monitoring records, SOP references and final qualification reports.
