ISO 11608-2:2022 defines requirements and test methods for single-use, sterile, double-ended pen needles used with certain needle-based injection systems (typically pen injectors) that use a non-integrated, double-ended needle interface.
It is commonly used in design verification, supplier qualification, and incoming QC for pen needle products where consistent fit, function, and basic performance checks are needed alongside ISO 11608-1 system-level expectations.

ISO 11608-2:2022 — Needle-based injection systems for medical use — Requirements and test methods — Part 2: Double-ended pen needles
ISO 11608-2 is a product-focused standard for pen needles that connect to needle-based injection systems using a non-integrated double-ended needle arrangement. It pairs “requirements” with “test methods,” so it is typically applied as both a compliance checklist and a verification test plan reference.
This standard is specific to double-ended pen needles (patient end and cartridge/pen end). It is not a general hypodermic needle test standard and should be applied only where the product and intended use match the scope.
Quick Definition
Document type: Requirements and test methods (mixed requirements + verification testing).
What it covers: Single-use, sterile, double-ended pen needles intended for use with certain needle-based injection systems that use a non-integrated double-ended needle interface.
What it does not cover: Many other needle categories (for example, dental needles, pre-attached syringe needles, general hypodermic needles, and needles intended for other administration routes).
What This Standard Covers
ISO 11608-2 focuses on the pen needle as a component: the needle assembly and its interfaces, and the verification tests used to demonstrate it meets the stated requirements. In practice, it is used to support repeatable evaluation of pen needle product performance and consistency.
Because pen needles are used with a compatible injection system, ISO 11608-2 is often applied alongside system-level requirements in ISO 11608-1, with additional references depending on whether the needle is integrated into a container/fluid path or provided separately.
Why This Standard Matters in Testing
Pen needles are medical device components where performance is closely tied to user experience, medication delivery reliability, and compatibility with the injection system. ISO 11608-2 gives manufacturers and labs a recognized framework for demonstrating that a pen needle design meets defined requirements using defined test methods.
For labs and QA/QC teams, the value is repeatability: using a known standard helps align internal verification, supplier requirements, and test reporting across product changes and across sites.
Common Materials, Product Types, or Applications Covered
Common product type: Single-use, sterile, double-ended pen needles intended to be attached to compatible needle-based injection systems (often used for self-administration therapies such as insulin delivery via pen injectors).
Common application context: Medical-device design verification, process validation support, and routine production or incoming inspection where pen needle performance must be demonstrated consistently.
Common Test or Verification Workflow
Workflows built around ISO 11608-2 typically follow a verification plan approach rather than a single bench test. Teams commonly use the standard to define which performance attributes to evaluate, how to run those evaluations, and what to record for technical documentation.
Common workflow points: design verification (DV), supplier qualification, incoming lot checks, and change-control re-verification when materials, geometry, or manufacturing processes change.
Equipment Commonly Used for This Standard
ISO 11608-2 is a requirements-and-test-methods document, so equipment selection typically depends on which clauses your lab is executing. Many programs use a combination of force measurement, dimensional inspection, and functional verification setups.
Common equipment families: force testing systems (e.g., motorized test stands or universal testing machines with appropriate fixtures), calibrated force gauges/load cells, dimensional metrology tools (optical or contact measurement as applicable), functional fit/attachment evaluation fixtures matched to the intended injection system interface, and leak/pressure evaluation equipment when needed by the selected test methods.
Practical purchasing caution: matching fixtures and measurement ranges to your specific pen needle design (and the exact ISO 11608-2 edition cited in your requirement) is often more important than the base frame capacity.
How to Read This Designation or Revision
Designation: “ISO 11608-2” identifies Part 2 within the ISO 11608 series for needle-based injection systems for medical use.
Edition and year: ISO standards are frequently cited with a year (for example, ISO 11608-2:2022). Requirements, referenced companion parts, and test details can change between editions, so purchase specifications and test plans should name the exact year being applied.
Legacy citations: You may still encounter older references to ISO 11608-2:2012 in documentation; ensure your quality system and customer/regulatory requirements specify whether the current edition or a legacy edition applies.
Related Standards, Methods, or Frameworks
ISO 11608-2 is commonly used with other documents depending on how the needle is supplied and how the injection system is configured.
-
ISO 11608-1: System-level requirements and test methods for needle-based injection systems used with non-integrated double-ended needles.
-
ISO 11608-3: Commonly referenced where needles are provided by the manufacturer integrated into the fluid path or container.
-
ISO 7864: Commonly referenced for hypodermic needles provided separately, when that needle category (rather than pen needles) is in scope.
