ISO 11607: Complete Guide to Medical Device Packaging Standards & Requirements

By Tanner Vandenberg, CEO, FlexPak Leak Detectors Inc.

ISO 11607 is the international standard for packaging terminally sterilized medical devices, meaning devices sterilized after they are sealed in their package. It has three parts. Part 1 covers the materials and the sterile barrier system itself. Part 2 covers validating the forming, sealing and assembly processes. Part 3, published in September 2026, covers developing the heat sealing process before you validate it.

We make leak detection equipment that medical packaging teams use for ISO 11607 integrity testing. This guide explains what each part asks for, where integrity testing fits, and which tests we can and cannot help with.

Understanding ISO 11607 Standards

The standard is built around one idea: the package has to keep the device sterile from the moment it is sterilized until someone opens it at the point of use. Everything in ISO 11607 supports that.

A few definitions do most of the work:

• Sterile barrier system (SBS): the minimum package that keeps microorganisms out and allows aseptic presentation of the device at the point of use. A sealed pouch or a lidded tray is a typical example.
• Preformed sterile barrier system: a sterile barrier system supplied partly assembled, such as a pouch sealed on three sides, which the device maker fills and closes.
• Protective packaging: the cartons, shippers and inserts that protect the sterile barrier system from damage.
• Packaging system: the sterile barrier system and its protective packaging together.

Key Components and Scope

ISO states that Part 1 applies to industry, to health care facilities, and wherever medical devices are placed in sterile barrier systems and sterilized. It also states what Part 1 does not do. It does not cover all requirements for aseptically manufactured devices. It does not describe a quality assurance system for every stage of manufacture. It does not apply to packaging used to return contaminated devices for reprocessing or disposal.

Does ISO 11607 apply to non-sterile medical devices?

No. ISO 11607 is written for terminally sterilized devices. Packaging for non-sterile devices is usually handled through the manufacturer’s general quality system and distribution testing, not ISO 11607.

Recent Updates and Amendments

• 2019: the current second editions of Part 1 and Part 2 were published. ISO reviewed and confirmed both in 2024, so they remain current.
• 2023: Amendment 1 to Part 1 and to Part 2 added the application of risk management.
• September 2026: ISO 11607-3 was published. It applies to both preformed sterile barrier systems and sterile barrier systems made with heat sealing.

Amendment 1 also clarified a point about test methods. Part 1 lists test methods in Annex B, and the amended note says publishing a method “does not make it validated by the user of the test method.” In other words, picking a method from the list is not enough. You have to validate it on your own package.

Requirements for Medical Device Packaging

Part 1 asks the manufacturer to show that the materials, the sterile barrier system and the full packaging system are right for the device, the sterilization method and the trip to the user.

Material Requirements

Materials have to be compatible with the sterilization method (for example ethylene oxide, radiation or steam), provide a microbial barrier, and not harm the device. Many teams use porous materials such as Tyvek so the sterilant can get in and out while microorganisms stay out. The material choice decides which integrity tests work later, because porous and nonporous materials test differently.

Sterile Barrier Systems

The sterile barrier system has to keep its integrity after sterilization, after shipping, and for the full labelled shelf life. It also has to open cleanly so the device can be presented without contaminating it. That is why ISO 11607 validation usually tests the package after conditioning, not just straight off the sealer.

Package Validation Testing

Validation under Part 1 usually combines three kinds of evidence: the package holds up over time, it survives distribution, and the seal and barrier stay intact. Here is how the common test methods line up, and which ones FlexPak equipment performs.

Stability and Shelf Life Testing

Stability testing shows the package still works at the end of its labelled shelf life. Most teams run accelerated aging to ASTM F1980 to get an early answer, and real-time aged samples to confirm it. The aged packages then go through the same integrity and seal strength tests as new ones.

Distribution Simulation Testing

Distribution testing puts the packaging system through the handling it will see in shipping, such as drops, vibration, compression and pressure changes, and then checks whether the sterile barrier survived. Altitude is easy to overlook. Packages shipped by air, especially on smaller feeder aircraft, see lower air pressure, which makes sealed pouches expand and stresses the seals. ASTM D6653 conditions packages to that pressure, and a leak test afterwards shows whether any seal opened.

Package Integrity Testing

Integrity testing answers the question that matters most: is there a hole or channel that could let microorganisms in? For medical pouches made with Tyvek, ASTM F2096 is the usual choice. The package is punctured, inflated to a set pressure under water, and a steady stream of bubbles shows the leak and exactly where it is.

Be clear about what F2096 can claim. The standard’s round-robin study found it detects a 250 µm (0.010 in) defect with about 81% probability, with that sensitivity established on spunbonded polyolefin (Tyvek). It is a destructive test, so it belongs in validation and sampling plans, not 100% inspection. Operators should exercise extreme caution when handling the needle at all times.

Seal integrity and seal strength are different things, and ISO 11607 validation normally needs both. See the difference between seal strength and seal integrity. For a step-by-step look at running these tests on a sterile barrier system, see our sterile barrier system testing guide.

Validation Requirements for Manufacturing

Part 2 is about the process, not a single package. You have to show that your forming, sealing and assembly processes consistently produce packages that meet Part 1. Part 3 now covers the development work that comes before that.

Sealing and Assembly

For heat sealing, the critical parameters are temperature, pressure and dwell time. Process development (the subject of Part 3) establishes the operating window for those parameters. ISO 11607-3 also recommends minimum heat sealing equipment features to support later validation, process control and monitoring.

Quality Control Measures

Part 2 validation follows the familiar three stages:

• Installation qualification (IQ): the equipment is installed correctly and calibrated.
• Operational qualification (OQ): the process makes acceptable packages across the full operating window, including its upper and lower limits.
• Performance qualification (PQ): the process makes acceptable packages consistently under normal production conditions.

After validation, routine monitoring confirms the process stays in control. That is where a fast integrity test on sampled production packages earns its place.

Regulatory Compliance and Documentation

In the United States, FDA lists ANSI/AAMI/ISO 11607-1:2019 and 11607-2:2019 as recognized consensus standards (recognition numbers 14-530 and 14-531). Manufacturers can declare conformity to them in premarket submissions.

Since February 2, 2026, FDA’s Quality Management System Regulation has replaced the old Quality System Regulation in 21 CFR Part 820. It incorporates ISO 13485:2016 by reference. For packaging teams, the practical effect is that packaging validation records are reviewed as part of a quality system aligned with ISO 13485.

Record Keeping Requirements

ISO 11607 expects documented evidence at each stage. Most packaging validation files include:

• Material specifications and supplier documentation
• The design rationale for the sterile barrier system and packaging system
• Test method validation for each integrity and strength test used
• IQ, OQ and PQ protocols and reports for forming, sealing and assembly
• Stability (aging) and distribution test results
• Routine monitoring records after validation

For integrity test records, the FlexPak touchscreen controllers store test recipes and log each result to an SD card, so every test has a date, a setting and a pass or fail result.

Risk Management Approach

Amendment 1 (2023) brought risk management into both Part 1 and Part 2. In practice, that means you identify how the packaging could fail, rate the risk to sterility, and use that to decide what to test, how many samples to test, and which process parameters to control most tightly.

ISO 11607: Quick Answers

What is the difference between ISO 11607-1, 11607-2 and 11607-3?

Part 1 covers the package: materials, design and performance. Part 2 covers validating the process that makes it. Part 3, published in 2026, covers developing the heat sealing process before it is validated.

Is ISO 11607 recognized by FDA?

Yes. FDA recognizes ANSI/AAMI/ISO 11607-1:2019 and 11607-2:2019 as consensus standards.

Which leak test should I use for ISO 11607 validation?

It depends on the material. ASTM F2096 is common for porous pouches such as Tyvek. ASTM D3078 suits nonporous flexible packages with headspace. Whichever you choose, the standard expects you to validate the method on your own package.
