Short answer
ISO 11608-1 is the international standard that sets requirements and test methods for needle-based injection systems (NISs): single-patient-use devices that deliver discrete bolus volumes of a medicinal product through a needle or soft cannula into the skin, under it or into muscle. The current edition is ISO 11608-1:2022, which replaces the 2014 edition. In plain language, a refillable or disposable pen-style injector is the kind of device people have in mind, but that wording is a gloss, not the standard’s own term. This page is general product information, not medical advice.
Definition and scope
According to the AFNOR standards-shop record for ISO 11608-1:2022 (checked 2026-10-30), the document “specifies requirements and test methods for Needle-Based Injection Systems (NISs) for single-patient use” that deliver discrete volumes (bolus) of medicinal product through needles or soft cannulas. The routes it names are intradermal, subcutaneous and intramuscular, and the systems it covers incorporate pre-filled or user-filled containers that are replaceable or non-replaceable. The official title is “Needle-based injection systems for medical use – Requirements and test methods – Part 1: Needle-based injection systems”.
The standard also applies where the NIS incorporates a prefilled syringe. A stand-alone prefilled syringe defined by ISO 11040-8 is a separate case and is not covered by ISO 11608-1.
How the standard is used in practice
ISO 11608-1 is a requirements-and-test-methods document, so it is the reference a manufacturer, test laboratory or regulatory reviewer cites when asking whether an injection system as a whole meets a defined performance specification. It describes the system that delivers the dose, not a loose component bought on its own. Where an injection system is combined with a drug, the regulatory pathway is a separate question; see how FDA assigns a lead center for combination products.
Scope boundaries: what ISO 11608-1 covers and what it does not
| Question | Answer from the sources | Source |
|---|---|---|
| Single-patient-use needle-based systems giving bolus doses by needle or soft cannula? | Covered | AFNOR record, 2026-10-30 |
| Intradermal, subcutaneous or intramuscular delivery? | Covered | AFNOR record, 2026-10-30 |
| A system that incorporates a prefilled syringe? | Covered | AFNOR record, 2026-10-30 |
| A stand-alone prefilled syringe defined by ISO 11040-8? | Not covered by ISO 11608-1 | AFNOR record, 2026-10-30 |
| Continuous-delivery systems such as insulin patch pumps? | Excluded | AFNOR record, 2026-10-30 |
| Dental-use systems? | Excluded | AFNOR record, 2026-10-30 |
| Intravenous, intrathecal or intraocular delivery? | Excluded | AFNOR and BSI Knowledge records, 2026-10-30 |
Edition and citation tracker
The same standard appears under different citation forms, which matters when a specification sheet or tender names it.
- ISO 11608-1:2022: published April 2022 per AFNOR, status current, 72 pages, replacing ISO 11608-1:2014, which AFNOR lists as cancelled.
- BS EN ISO 11608-1:2022: the UK adoption, published 30 June 2022 per BSI Knowledge, identical to EN ISO 11608-1 and ISO 11608-1. BSI shows its status as “Current, Under Review” and lists no amendments on that page.
Both citations point to the same technical content. A document that cites only “ISO 11608” without a part number or year does not identify which edition it means.
Related standards and which question each answers
ISO 11608 is often grouped with syringe and needle standards, but each answers a different question. The table below sets out the main ones.
| If the question is about… | Look at | Further reading on CASRAI |
|---|---|---|
| A complete needle-based injection system (pen-style or similar) | ISO 11608-1 | Insulin pen storage |
| Sterile single-use hypodermic syringes for manual use: dead space, leakage, piston force, plunger fit | ISO 7886-1 | Low dead space syringes and 10 mL syringes |
| Needle gauge and tubing dimensions | ISO 9626 | Needle gauge chart and hypodermic needles |
| A stand-alone prefilled syringe | ISO 11040-8 | – |
ISO 7886-1 is titled “Sterile Hypodermic Syringes for Single use – Part 1: Syringes for Manual use”. Its test procedures and minimum performance specifications cover dead space, leakage (air and water), operating piston force and the fit of the plunger in the barrel, as described in a peer-reviewed review (Krisdiyanto et al., Medicine 101(49):e31812, checked 2026-10-30).
Where it matters for supply decisions
Procurement and regulatory staff meet these standards as citations on product documentation. The useful habit is to match the question to the standard: a pen-style system’s conformity is a question for ISO 11608-1, a manual syringe’s dead space is a question for ISO 7886-1, and a needle’s gauge designation is a question for ISO 9626. Also record the part number and year, because the 2022 edition replaced the 2014 one.
Common misunderstandings
“ISO 11608 is the syringe standard.”
It is not. Manual hypodermic syringes are the subject of ISO 7886-1, and stand-alone prefilled syringes fall under ISO 11040-8. ISO 11608-1 covers the injection system as a whole.
“It covers every wearable or automatic injector.”
Not according to the scope record: continuous-delivery systems such as insulin patch pumps are excluded, as are dental-use systems and intravenous, intrathecal or intraocular delivery.
“ISO 11608 and BS EN ISO 11608 are different requirements.”
BSI describes BS EN ISO 11608-1:2022 as identical to EN ISO 11608-1 and ISO 11608-1, so the technical content is the same and only the national citation differs.
Frequently asked questions
What is ISO 11608-1?
It is the international standard that specifies requirements and test methods for needle-based injection systems for single-patient use, covering bolus delivery through needles or soft cannulas by the intradermal, subcutaneous or intramuscular route. The current edition is ISO 11608-1:2022.
Does ISO 11608-1 cover syringes?
Only where a prefilled syringe is incorporated in a needle-based injection system. Stand-alone prefilled syringes fall under ISO 11040-8, and manual hypodermic syringes are the subject of ISO 7886-1.
Are insulin patch pumps covered?
No. Systems giving continuous delivery at a clinically specified rate, such as insulin patch pumps, are excluded from the scope.
Which edition is current?
ISO 11608-1:2022 (April 2022) replaces ISO 11608-1:2014, which AFNOR lists as cancelled. BS EN ISO 11608-1:2022 is the UK adoption.
Is ISO 11608 the same as ISO 7864 or ISO 9626?
No. Each answers a different question: ISO 11608-1 covers the injection system as a whole, while needle gauge and tubing dimensions are the subject of ISO 9626 (see the needle gauge chart).
