If you make or convert packaging for terminally sterilized medical devices, ISO 11607 isn’t optional reading — it’s the standard FDA and EU regulators point to when they ask how you know your pouches, trays, or wraps keep a device sterile until the moment it’s opened. Getting it wrong means failed audits, recalled lots, or a device that reaches a clinician with a compromised sterile barrier.
This guide breaks down what ISO 11607-1 and ISO 11607-2 actually require, what a validation project looks like in practice, which ASTM test methods you’ll need, and the mistakes that most often trip up packaging teams during audits or FDA submissions.
Quick Answer
ISO 11607 is a two-part international standard (Part 1: materials and sterile barrier system design; Part 2: validation of forming, sealing, and assembly processes) that defines how packaging must protect a terminally sterilized medical device, allow sterilization to occur, maintain sterility until use, and permit aseptic presentation. Compliance means validating your materials, your seal/package design, and your manufacturing process — not just running a single lab test.
What ISO 11607-1 and ISO 11607-2 Actually Cover
ISO 11607-1:2019 sets requirements for materials, preformed sterile barrier systems, sterile barrier systems, and full packaging systems. It covers things like biocompatibility of materials, microbial barrier properties, compatibility with your chosen sterilization method (EO, steam, radiation, etc.), physical and chemical stability during storage and transport, and — since the 2019 revision — clearer criteria for evaluating usability for aseptic presentation, plus guidance distinguishing a sterile barrier system from protective packaging that merely cushions the product.
ISO 11607-2:2019 covers validation of the processes that actually create the sterile barrier: forming, sealing, and assembly (including kitting). This is where installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) come in — you’re proving that your sealing equipment is installed correctly, that it runs within a validated process window, and that it consistently produces conforming seals across your real production range, not just under ideal conditions.
Both parts received Amendment 1 in 2023, which folds in a more explicit risk-management framework (aligned with ISO 14971 thinking) without changing the underlying test and validation requirements. If your quality system references the 2019 editions, check whether your procedures also need to reflect the 2023 amendment.
Building a Validation Program That Holds Up in an Audit
Start with material and design qualification: confirm your chosen film, foil, or Tyvek combination is compatible with your sterilization modality and passes the physical property tests relevant to your use case (e.g., seal strength, porosity, tear resistance) before you commit to full process validation.
Move to process validation (IQ/OQ/PQ) on your actual sealing equipment. IQ documents the equipment is installed per specification; OQ establishes and challenges the operating range (temperature, pressure, dwell time) to find your process window; PQ confirms the process reliably produces good seals across multiple production lots using product in its final configuration.
Run your seal strength and seal integrity testing as separate exercises — ISO 11607 treats them as distinct requirements. Seal strength (the mechanical force needed to peel a seal apart) is typically measured with ASTM F88. Seal integrity (whether there’s an actual leak path or channel defect) is verified with a different method depending on your material: ASTM F1929 dye penetration for porous materials like Tyvek, ASTM F3039 for nonporous foil/film seals, or ASTM F2096 bubble/vacuum leak testing for gross leaks. Burst and creep testing (ASTM F1140 and F2054) round out the destructive test package for many packaging systems.
Finally, validate shelf life with real-time and/or accelerated aging protocols so you can support the sterility maintenance claim on your labeling, and build a transport/distribution simulation (commonly referencing ASTM D4169) into your validation so the package survives the environmental and handling stresses of actual shipping.
Tips and Common Mistakes
Don’t treat ISO 11607 as a one-time lab report. Auditors and FDA reviewers want to see the full chain: material qualification, process validation with IQ/OQ/PQ, and ongoing verification tied to your change-control process — a single third-party test certificate isn’t a validation.
Don’t skip revalidation after a ‘minor’ change. A new sealing bar temperature setpoint, a different film supplier lot, or a packaging line relocation can all invalidate a prior PQ. Build a change-impact assessment into your process so these triggers aren’t missed.
Don’t confuse seal strength with seal integrity. A seal can pass a peel-strength spec and still have a channel defect that compromises the barrier — that’s exactly why ISO 11607 requires testing both, using different methods.
Don’t forget the aseptic presentation requirement. ISO 11607-1 expects you to demonstrate that a clinician can open the package and remove the device without contaminating it — this is a usability evaluation, not just a materials test.
Since 2019 (and reinforced by the 2023 amendment), make sure your packaging risk assessment is documented and traceable, ideally linked to your broader ISO 14971 risk management file rather than treated as a standalone packaging exercise.

ISO 11607 FAQs
Is ISO 11607 mandatory for medical device manufacturers?
ISO 11607-1 and -2 are FDA-recognized consensus standards and harmonized standards under the EU MDR, so while adoption is technically voluntary, regulators expect compliance in practice — most 510(k), PMA, and MDR technical file submissions reference conformance to these standards for terminally sterilized devices.
What’s the difference between ISO 11607-1 and ISO 11607-2?
Part 1 covers requirements for packaging materials and sterile barrier system/packaging system design. Part 2 covers validation of the manufacturing processes — forming, sealing, and assembly — used to create that packaging, typically through IQ/OQ/PQ.
Does a small packaging or process change require full revalidation?
It depends on the risk impact of the change. Changes to materials, seal parameters, equipment, or facility location typically require at least a documented impact assessment, and often partial or full revalidation, to maintain your ISO 11607-2 validation status.
What test methods are used for seal integrity versus seal strength?
Seal strength is commonly tested with ASTM F88 (peel testing). Seal integrity uses different methods depending on material: ASTM F1929 dye penetration for porous materials like Tyvek, ASTM F3039 for nonporous film/foil, and ASTM F2096 for gross leak detection.
