Prefilled syringes are one of the more complex drug-device combinations. ISO 11040 is a series of standards that establishes the requirements, dimensions, materials, performance, and testing for prefilled syringes and their components used in pharmaceutical applications.
The packaging must protect both the drug product and the delivery mechanism while simultaneously meeting sterile barrier and shelf-life requirements, compatibility demands, and functional performance. It is used primarily by pharmaceutical and medical device industries to ensure that syringes perform reliably in clinical settings. Understanding the full scope of ISO 11040, including its individual parts and the test methods tied to each, is an important starting point.
Packaging for Prefilled Syringes
Packaging is an active component of the drug-device combination. The primary packaging components, including the barrel, plunger stopper, tip cap, and needle shield, must maintain compatibility with the drug product while preserving sterile barrier integrity through sterilization, distribution, storage, and end-use. Any compromise in these components can affect both product safety and clinical performance.
ISO 11040 Parts Supported by PCL:
ISO 11040 - Part 4: Glass barrels for injectables and sterilized subassembled syringes ready for filling.
ISO 11040 – Part 5: Plunger stoppers for injectables.
ISO 11040 - Part 6: Plastic barrels for injectables and sterilized subassembled syringes ready for filling
ISO 11040 - Part 8: Requirements and test methods for finished prefilled syringes
Parts 4 & 6: Prefilled syringe subcomponents
ISO 11040 Parts 4 and 6 define the requirements for the primary components of prefilled syringes: glass barrels, plastic barrels, and plunger stoppers. Each standard outlines the applicable dimensional specifications, material characteristics, and performance requirements for its respective component.
Glass barrels covered under ISO 11040-4 are typically manufactured from Type I borosilicate glass, selected for its chemical resistance and compatibility with a wide range of drug formulations.
Plastic barrels under ISO 11040-6 are commonly produced from cyclic olefin polymer (COP) or cyclic olefin copolymer (COC), materials valued for their break resistance and lower risk of glass delamination. Plunger stoppers, addressed separately under ISO 11040-5, must be evaluated alongside the barrel to confirm proper break loose and glide force, and dimensional characteristics.
Part 8: Finished syringe requirements and Test Methods (Updated 2026)
Part 8 evaluates the complete syringe rather than it’s individual subcomponents. The 2026 revision to ISO 11040-8 introduces several updates. Key updates include an expanded definition of intended use, formalizes Break Loose and Extrusion Force testing in Annex A, consolidates leakage and burst resistance testing in Annex C, and introduces a new Administration Time test method in Annex D.
Frequently asked questions
When are ISO 11040 evaluations performed?
ISO 11040 evaluations are performed throughout the manufacturing process. Testing may support component selection, design verification, supplier qualification, stability, distribution studies, lot release, or regulatory submissions.
How many test methods are associated with ISO 11040?
There are over 100 combinations of devices and test methods covered by ISO 11040 series of standard.
What products are covered by ISO 11040?
The standard applies to prefilled syringe systems and individual syringe components used in pharmaceutical drug delivery applications. Specific products covered depend on the individual part of the ISO 11040 series.
Does ISO 11040 apply to complete syringe systems?
Yes. ISO 11040 includes both component-level requirements and finished syringe system testing, particularly under ISO 11040-8.
