Full title and description

ISO 11608-3:2022 — Needle-based injection systems for medical use — Requirements and test methods — Part 3: Containers and integrated fluid paths. Edition 3 (published 7 April 2022; corrected version January 2023). Specifies design verification requirements and test methods for containers (cartridges, syringes, reservoirs) and fluid paths that are integrated with needle-based injection systems (NISs).

Abstract

This part of ISO 11608 defines the functional requirements and specific test methods used to verify containers and integrated fluid paths intended for use with needle-based injection systems in accordance with ISO 11608-1. It covers single- and multi-dose primary containers (manufacturer-filled or end-user filled) and integrated fluid-path components, and sets acceptance criteria for key performance attributes such as resealability, particulate burden, leakage, break‑loose and sustaining forces, and disc fragmentation. The document excludes certain products (see Scope).

Scope

Applies to design verification of single- and multi-dose containers and integrated fluid paths used with needle-based injection systems (NISs) covered by ISO 11608-1. Examples include cartridges, reservoirs and syringes (including prefilled syringes when used with a NIS). The standard addresses functional and safety-relevant tests performed at design verification and appropriate acceptance criteria. It does not apply to sterile hypodermic needles or sterile hypodermic syringes sold separately, single-use insulin syringes, containers intended to be refilled multiple times, containers for dental use, or catheters/infusion sets that are assembled or attached separately by the user.

Key topics and requirements

• Design verification of containers and integrated fluid paths to ensure safe, compatible use with NISs.
• Resealability testing for multi‑dose elastomeric access (specified penetration cycles and post‑penetration performance).
• Disc fragmentation (coring) limits and methods for detecting elastomeric fragments produced by needle access.
• Particulate matter requirements and limits (sub‑visible and visible) for reservoir/fluid-path contributions; recommended numerical limits for common particle size bands.
• Break‑loose and sustaining force tests for plungers/pistons to verify user‑perceived forces and dose delivery consistency.
• Leakage and container integrity tests under defined loading/pressurization conditions.
• Dimensional and interface compatibility checks to confirm correct mechanical fit and safe assembly with the intended NIS.
• Material and medicinal‑product compatibility considerations, including impact on dose accuracy and patient safety.
• Test methods, sample sizes and acceptance criteria intended for design verification and risk‑based assessment.

Typical use and users

Used by medical device and pharmaceutical manufacturers (design and R&D teams), contract testing laboratories, quality assurance and regulatory affairs professionals, device integrators and suppliers of cartridges, prefilled syringes and integrated fluid-path components. Also referenced by clinical engineers and notified bodies during conformity assessment for NISs.

Related standards

ISO 11608-1 (general requirements and definitions for NISs); ISO 11608-2 (pen needles); ISO 11040 series (pre-filled syringes; see ISO 11040-8 as referenced); applicable pharmacopeial monographs and regional device/packaging standards; previous edition ISO 11608-3:2012 (withdrawn). Amendment 1 to ISO 11608-3:2022 is under development to update specific clauses (e.g., particulate requirements).

FAQ

Q: What is this standard?

A: ISO 11608-3:2022 (corrected January 2023) is Part 3 of the ISO 11608 series and specifies requirements and test methods for containers and integrated fluid paths used with needle-based injection systems.

Q: What does it cover?

A: It covers design verification tests and acceptance criteria for primary containers and integrated fluid paths (cartridges, reservoirs, syringes) used with NISs, including resealability, disc fragmentation (coring), particulate limits, leakage, and plunger force characteristics. It also identifies products and situations that are excluded from the scope.

Q: Who typically uses it?

A: Device and drug-device combination manufacturers, suppliers of cartridges and prefilled syringes, test laboratories, QA/regulatory teams, and conformity assessment bodies involved in evaluating needle-based injection systems.

Q: Is it current or superseded?

A: The 2012 edition was superseded by ISO 11608-3:2022 (Edition 3), published 7 April 2022; a corrected text was issued in January 2023. The 2022 edition is the current published edition; an amendment (FDAmd 1) has been developed to update selected clauses.

Q: Is it part of a series?

A: Yes — ISO 11608 is a multi‑part series addressing needle‑based injection systems. Key related parts include ISO 11608-1 (general requirements) and ISO 11608-2 (pen needles); other related standards include ISO 11040 (pre‑filled syringes) referenced where relevant.

Q: What are the key keywords?

A: Needle-based injection systems, containers, cartridges, prefilled syringe, fluid path, resealability, disc fragmentation, particulate matter, leakage, break‑loose force, sustaining force, design verification, ISO 11608-3.
