Cleanroom Validation IQ/OQ/PQ

-- Steady & Reliable Manufacturer --

Cleanroom Validation IQ/OQ/PQ Overview

Validation is the documented proof that a cleanroom is built correctly and performs as intended. Pharmaceutical and other regulated plants follow a standard sequence: design qualification (DQ), installation qualification (IQ), operational qualification (OQ) and performance qualification (PQ). Together they show that the room was designed, installed and operated to meet its purpose.

Pharma United Co., Ltd. manufactures cleanroom panels, doors, windows, equipment and modular PODs near Shanghai. We do not replace your validation team or an independent testing company, but we support qualification by providing clear drawings, component data, factory records and technical answers that make the work faster.

What you will find under this tag:

  • Drawings and bills of materials that match what was built.
  • Component data, such as material specifications, filter efficiency records and wiring diagrams.
  • Factory inspection and function test records for panels, doors and equipment.
  • Installation checklists that feed into IQ.
  • Technical support for protocol preparation and test planning.

Who it is for: pharmaceutical, biotech, medical device, hospital pharmacy and laboratory owners, and the validation engineers and consultants who work for them.

A clear note: qualification testing must be carried out by qualified people with calibrated instruments, and the final approval belongs to your quality unit.

Our team reviews your document list and schedule, and tells you honestly what we can supply from the factory and what must come from other parties, such as the HVAC contractor and the testing company. We reply promptly and in plain language.

Technical Parameters and Qualification Activities

The stages build on each other. Your validation master plan, your risk assessment and the standards you follow define the exact tests. The table shows typical activities for a cleanroom, with common references such as ISO 14644 and EU GMP Annex 15.

StagePurposeTypical activities
DQShow the design meets the user requirementsReview of drawings, specifications and risk assessment
FAT (factory acceptance)Check equipment at the factoryFunction tests of doors, interlocks, Pass Boxes, booths
IQShow the room is installed as designedCheck of components against drawings, material records, calibration status, utilities
OQShow the room operates within set limitsHEPA leak tests, airflow volume and velocity, pressure differentials, interlock and alarm tests, temperature and humidity mapping
PQShow the room performs under real conditionsParticle counts at rest and in operation, recovery tests, airflow visualization, microbial monitoring
Re-qualificationShow continued performancePeriodic tests, commonly every 6 months for ISO 5 or cleaner and 12 months for others

Common test methods (ISO 14644-3 and related):

  • Airborne particle count: sampling locations and volumes follow ISO 14644-1.
  • Installed filter leak test: aerosol photometer or particle counter scan of each HEPA filter and its seal.
  • Airflow: velocity at terminal filters and air change rate.
  • Pressure differential: between rooms, with calibrated gauges.
  • Recovery: time for a room to return to class after a challenge.
  • Airflow visualization: smoke studies to show flow patterns.

Cross-Border Delivery and Localized Construction Support

Qualification starts long before the testing day. For overseas projects, the paperwork that will be needed at IQ should be collected during manufacture and shipping, not rebuilt afterward. We therefore prepare documents along the way.

  1. Document plan: we agree with your team which documents are needed for DQ, FAT and IQ.
  2. Factory stage: we record inspection results, function tests and filter data, and can support witnessed tests.
  3. Shipping stage: packing lists and batch records link each item to its documents.
  4. Installation stage: checklists and as-built drawings are kept during construction.
  5. Test stage: we answer technical questions and provide information to the testers.

Local conditions: testing companies and calibration services differ by country. Plan early who will perform the tests, with which instruments, and when, since qualified testers may have waiting times. Local regulators may also require a local entity or specific accredited laboratory.

To avoid failure at OQ, the room should be clean, sealed and balanced before testing begins, with HEPA filters installed and the HVAC commissioned. Your team remains responsible for protocols, execution and approval, and we support them with technical information.

Please also tell us your validation timeline and the date of your inspection or audit. Working backward from that date, we can agree when each document must be ready and when shipments must arrive, so that qualification is not delayed by missing papers.

Staged shipments can also be arranged when the building is handed over in phases.

Our staff reply promptly and in plain language, and our designers can adapt standard layouts to your building and your process.

Quality Control and Certification

Qualification relies on traceable records. No wall panel or door is "validated" on its own, since validation applies to the finished room and its operation. We make sure the parts we supply come with the records that your validation file needs.

RecordContentUse in qualification
Material specificationFace, core, profiles, gaskets, glassIQ component identity
Factory inspection recordDimensions, flatness, bonding, edge sealingIQ and acceptance
Function test recordInterlock, door, Pass Box, booth testsFAT and OQ preparation

Batch and packing recordsLink between items and documentsTraceability

Documents available: the records above and, where available, reports on fire or surface performance. Please give us your document list early. We will confirm what exists and will not claim records that do not exist.

Customer audits of our factory, witnessed factory tests and sample approvals are welcome, and we can adjust our schedule to your FAT plan.

Validation teams and auditors often ask how component records are kept and linked to the installed rooms. We use position codes and batch numbers that connect each panel, door and filter to its inspection record, and we share the system with you. Our factory can host audits or witnessed tests.

We recommend agreeing the document list and the format of records at the start, so that nothing is missing when the IQ binder is assembled.

Our staff reply promptly and in plain language, and our designers can adapt standard layouts to your building and your process.

After-Sales Service and Response Capability

Qualification is not a one-time event. Rooms are re-qualified regularly, and any change must be assessed. We keep complete project records that help with each cycle.

  • Fast communication: technical questions answered in English by email, phone or messaging.
  • Document retrieval: we can re-send records, drawings and certificates when your auditors ask.
  • Failure analysis support: if a test fails, we review photos and data to help find the cause.
  • Change support: updated drawings and component information for change control.
  • Spare parts: like-for-like parts that keep the qualified state.

Common test failures and likely causes:

FailurePossible causeSuggested action
HEPA leak at filter edgePoor seal or damaged filterRe-seat or replace filter, retest
Pressure below targetLeaks at joints or doors, HVAC balanceSeal, replace gasket, rebalance
Particle counts high at restDirty room, filter leak, poor cleaningClean, fix leak, retest
Slow recoveryLow air changes or poor airflow patternReview HVAC and layout

Keep baseline results from the first qualification, which help detect slow changes over time.

When a re-qualification test fails or drifts, speed and clarity matter. Please send the test report, the room name, the date and any recent changes, such as new equipment, new openings or filter changes. Our engineers will compare them with the project drawings and records and suggest likely causes and corrective steps.

Replacement parts are made to the original specification, so the qualified state is kept. For urgent cases, we discuss the fastest shipping option and prepare documents in advance.

A small stock of gaskets, sealant and filters at the site helps you act the same day.

Commercial Terms, Warranty and Lifecycle Cost

Qualification has a cost in time, testing and documents, and failing a test costs more. A well-built, well-documented room usually qualifies faster and needs fewer repeats.

ItemOur approach
Standard documentsMaterial specifications, factory records, wiring diagrams provided with the order
Extra documentationAdditional document packs or witnessed tests can be quoted separately
Trade termsFOB, CFR or CIF, defined in the quotation
PaymentCommonly a deposit with balance before shipment or against documents; final terms in the contract
WarrantyDefined by component group in the contract
Third-party testingArranged and paid by the owner unless agreed otherwise

Where qualification cost is decided:

  • Number of rooms and grades: each room needs its own tests.
  • Re-test frequency: cleaner classes need more frequent testing.
  • First-time pass rate: sealing and installation quality reduce repeats.
  • Documentation effort: clear records from the start reduce consultant time.

Protocol writing, testing, calibration, consultants and regulatory fees are outside our supply unless agreed. Warranty exclusions are stated clearly in the contract.

When budgeting for qualification, include the cost of instruments and their calibration, tester time, repeat tests, consultant time and document control. The earlier these are planned, the less they surprise the project.

We provide itemized quotations for our supply and for optional document packs, and we are glad to explain every line.
