Medical Device Process Validation Services
Medical device process validation is the documented process of establishing, through objective evidence, that a manufacturing process will consistently produce a device meeting its predetermined specifications — every single time. The U.S. FDA defines it under 21 CFR 820.75 as: “establishing by objective evidence that a process consistently produces a result or product meeting its predetermined specifications.”
In simple terms: when you cannot fully verify the output of a manufacturing step through inspection or testing alone — such as sterilization, injection molding, welding, or aseptic processing — you must validate the process itself. This is not optional. Both FDA (21 CFR 820.75) and ISO 13485:2016 Section 7.5.6 mandate it. As of February 2026, the new QMSR regulation has fully aligned FDA requirements with ISO 13485, making robust process validation even more critical for US market access.
TRACC Global helps medical device manufacturers across the USA execute compliant, audit-ready process validation programs that protect patients and prevent costly FDA warning letters.
When Is Medical Device Process Validation Required?
The core question every manufacturer must answer: Can the output of this process be fully verified through inspection and testing alone? If the answer is no — validation is required by law.
| PROCESS TYPE | WHY VALIDATION IS REQUIRED | REGULATORY REFERENCE |
|---|---|---|
| Sterilization (ETO, Gamma, Steam) | Sterility cannot be verified without destroying the product — outcome must be guaranteed through process control | FDA 21 CFR 820.75 / ISO 11135 |
| Injection Molding & Welding | Internal defects may not be visible post-production; consistent parameters ensure structural integrity | GHTF SG3 Guidance / ISO 13485 |
| Aseptic Filling & Packaging | Microbial contamination cannot be fully tested in finished product batches without risk | FDA 21 CFR 820.75 |
| Sterile Barrier Packaging (Heat Seal) | Seal integrity testing is often destructive — validation proves the process reliably maintains sterility | ASTM F2097 / ISO 11607 |
| Plating, Coating & Surface Treatment | Surface properties like adhesion and uniformity cannot be verified without compromising the device | GHTF SG3 / ISO 13485 §7.5.6 |
| Lyophilization (Freeze-Drying) | Final product moisture content and stability cannot be individually tested for every unit | FDA Process Validation Guidance |
| Software Used in Manufacturing (QMS) | Software validation required under ISO/TR 80002-2:2017 and FDA CSA guidance for QMS-critical applications | 21 CFR 820 / ISO 80002-2 |
| Cleanroom Environmental Controls | Air particle counts and bioburden cannot be verified on every production unit | ISO 14644 / GHTF SG3 |
The IQ, OQ, PQ Framework — Explained Simply
Medical device process validation follows a structured three-phase qualification approach recognized by both FDA and ISO 13485. TRACC Global manages all three phases with complete documentation, risk-based evidence, and audit-ready protocols.
IQ : Installation Qualification — “Is Everything Installed Correctly?”
IQ verifies and documents that all equipment, utilities, instruments, and auxiliary systems are installed according to manufacturer specifications and your facility requirements. This includes equipment design features, environmental conditions, safety features, calibration baselines, and spare parts documentation. If the foundation is wrong, every run after it is suspect. TRACC Global conducts thorough IQ reviews aligned with FDA 21 CFR 820.70(g) and ISO 13485 §7.5.6 — ensuring nothing is overlooked before a single unit is produced.
OQ: Operational Qualification — “Does It Work as Designed Under All Conditions?”
OQ challenges equipment across its full operating range — including worst-case conditions — to confirm it performs within defined parameters. This includes validating process control limits, testing failure modes, reviewing change control procedures, and running software verification if applicable. Our team designs OQ protocols that push your equipment to its limits so that regular production never gets close to them. Process control limits established in OQ become the guardrails for every subsequent production run.
PQ: Performance Qualification — “Does the Process Consistently Produce Compliant Devices?”
PQ is the proof. Conducted under actual production conditions using real materials, real operators, and normal process parameters, PQ demonstrates that your process reliably and repeatedly produces devices meeting all predetermined specifications. TRACC Global designs statistically rigorous PQ protocols, including appropriate sampling plans, acceptance criteria, and capability studies (Cpk/ppk). A successfully completed PQ enables formal process release for full-scale production — and gives you the confidence to face any FDA inspector.

Frequently Asked Questions (FAQ)
What is medical device process validation under FDA 21 CFR 820?
Medical device process validation under FDA 21 CFR 820.75 is the documented practice of establishing, through objective evidence, that a manufacturing process will consistently produce a device meeting its predetermined quality and performance specifications. The FDA requires validation specifically for processes where the output cannot be fully verified through inspection or testing of the finished product alone — such as sterilization, welding, molding, and aseptic processing. As of February 2026, the QMSR has aligned this requirement with ISO 13485:2016 Section 7.5.6, making the standard more globally harmonized.
What are IQ, OQ, and PQ in medical device process validation?
IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification) are the three sequential phases of medical device process validation. IQ confirms equipment is installed correctly per manufacturer specifications. OQ challenges the process across its full operating range — including worst-case conditions — to verify it performs within defined parameters. PQ demonstrates that the process consistently produces compliant devices under real production conditions using actual materials and personnel. Together, these three phases provide the objective, documented evidence required by FDA and ISO 13485 to release a process for full production.
Which medical device processes require validation?
Any manufacturing process where the output cannot be fully verified through inspection or testing of the finished product must be validated. Common examples include: sterilization (ETO, gamma radiation, steam), aseptic filling and processing, injection molding, welding (ultrasonic, laser), heat-seal packaging, surface treatments (plating, coating), lyophilization, and cleanroom environmental controls. Software used in manufacturing or quality management systems also requires validation. The GHTF SG3 N99-10 guidance document provides a process validation decision tree to help manufacturers determine which processes require formal validation.
What is the difference between process validation and design validation in medical devices?
Design validation confirms that the finished medical device meets user needs and intended use — it answers “did we build the right product?” Process validation confirms that the manufacturing process consistently produces a device meeting its design specifications — it answers “can we build this product correctly, every time?” Design validation typically involves clinical evaluation, usability testing, and performance testing of the final device. Process validation involves IQ/OQ/PQ studies on the manufacturing equipment and methods. Both are required under FDA 21 CFR Part 820 and ISO 13485, but they address fundamentally different questions. Most companies conduct design validation in the final stages of product development, while process validation happens before and during scale-up to commercial production.
When does process validation need to be revalidated for a medical device?
Process revalidation is required whenever changes occur that could affect the validated state of the process. Triggers include: significant equipment changes or equipment relocation, changes in raw materials or component suppliers, changes in the manufacturing environment, significant personnel changes, process deviations or out-of-spec results, and facility moves. For critical processes like sterilization, periodic revalidation every 2–3 years is advisable even without changes, per ISO/TR 80002-2:2017. Under QMSR 2026, manufacturers must have formal procedures defining exactly when and how revalidation is initiated and documented.
How long does medical device process validation take?
The timeline for medical device process validation varies depending on the complexity of the process, number of process parameters, device class, and whether validation activities run sequentially or in parallel. For a single manufacturing process (e.g., heat-seal packaging), a well-organized IQ/OQ/PQ can be completed in 6–12 weeks. More complex programs involving multiple processes, sterilization validation, and statistical analysis typically require 3–6 months. TRACC Global begins with a clear validation master plan that defines your specific timeline upfront — so there are no surprises mid-project.
What happens if a medical device manufacturer fails FDA process validation inspection?
Process validation remains one of the top 3–5 FDA inspection deficiencies found in warning letters every year under 21 CFR 820.75. If FDA finds process validation deficiencies, they issue a Form 483 observation requiring a formal Corrective Action Response. Repeated or unresolved deficiencies can escalate to a Warning Letter, import alerts, or even consent decrees. These actions disrupt production, damage brand reputation, and are extremely expensive to remediate. The most effective strategy is proactive: having well-documented, risk-based IQ/OQ/PQ protocols before an FDA inspection, not after. TRACC Global helps manufacturers achieve this proactively.
Does ISO 13485 certification mean my process validation is FDA compliant?
Under the new QMSR regulation effective February 2026, ISO 13485:2016 is now incorporated by reference into 21 CFR Part 820, which significantly narrows the gap between ISO and FDA requirements. However, ISO 13485 certification alone does not guarantee full FDA compliance. The FDA has specific additional requirements beyond ISO 13485 — particularly around complaint records, UDI, and traceability — and FDA inspections evaluate the effectiveness of your QMS in practice, not just certification status. TRACC Global ensures your process validation program satisfies both ISO 13485 and FDA-specific requirements simultaneously.
