ISO 11607-1 specifies requirements for materials, sterile barrier systems, and packaging systems. ISO 11607-2 covers validation requirements for forming, sealing, and assembly processes. The sterile barrier system must allow sterilization, keep the device sterile until use and allow aseptic presentation. Part 1 requires testing of material properties, seal strength, package integrity (such as dye penetration or bubble tests) and stability, often through accelerated and real-time aging. Part 2 requires installation, operational and performance qualification of sealing and forming processes. Both parts were amended in 2023.

Why it matters

Co-cited with sterilization standards in FDA Recognized Standards; packaging changes commonly drive Letter-to-File vs new submission decisions.

Common pitfalls

•A common mistake is failing to consider the entire life cycle of the device when designing packaging, leading to sterility breaches during transport or storage.
•Companies often underestimate the rigor required for process validation under ISO 11607-2, resulting in inadequate documentation and potential regulatory findings.
•Assuming that a packaging material approved for one device is suitable for another without re-evaluation is a frequent error.
•Neglecting to perform ongoing monitoring and revalidation of packaging processes can lead to undetected issues over time.
•Failing to conduct comprehensive usability testing of the sterile barrier system can result in issues during aseptic presentation by end-users.

Why compare MedTech terms side by side?

MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.

Common comparison patterns

Regulatory pathway choice - 510(k) vs PMA, 510(k) vs De Novo, Abbreviated vs Special 510(k).
Quality systems - QSR vs ISO 13485, QMSR vs QSR.
Software classification - SaMD vs SiMD, Locked vs adaptive AI.
EU frameworks - MDR vs IVDR, CE Mark vs UKCA.
Cybersecurity artifacts - SPDX vs CycloneDX SBOM, CVE vs CVSS.
Post-market actions - Recall vs field action, Removal vs correction.
