Overview
EN ISO 7886-3:2020 (CEN adoption of ISO 7886-3:2020) specifies the required properties and performance of sterile, single‑use hypodermic syringes that incorporate an auto‑disabled (AD) feature and are intended to deliver a fixed vaccine dose immediately after filling. The standard applies to syringes made of plastic, rubber or other materials, with or without an integrated needle and optional sharps‑protection features. It defines general requirements, testing methods and packaging/labeling expectations but does not prescribe the detailed design of the auto‑disable mechanism nor address compatibility with specific injection fluids or vaccines.
Keywords: EN ISO 7886-3:2020, auto‑disable syringe, fixed‑dose immunization, sterile single‑use syringe, syringe performance requirements.
Key topics
- Scope & exclusions
- Covers AD syringes for fixed‑dose immunization.
- Excludes insulin syringes (ISO 8537), pumps (ISO 7886‑2), reuse‑prevention syringes (ISO 7886‑4), and prefilled syringes (ISO 11040 series).
- Materials & construction
- Permits plastic, rubber or other materials; allows syringes with or without needles and needle protection.
- Performance requirements
- Tests for dead space, freedom from air and liquid leakage, and mechanical performance after shipping.
- Specific attention to the auto‑disable feature (test method provided in Annex C).
- Usability & dimensional checks
- Requirements for barrel dimensions, tolerances on nominal capacity, graduated scales, plunger/stopper fit and fiducial markings.
- Safety & cleanliness
- Limits for extraneous matter, acidity/alkalinity and extractable metals; lubricant acceptance criteria.
- Packaging & labeling
- Unit sterile barrier packaging, multiple‑unit packs, user packaging and manufacturer information requirements.
- Test methods
- Normative and informative annexes (e.g., extract preparation, piston forces, AD test method).
Applications
Who uses this standard:
- Syringe manufacturers - design verification, production QA and conformity assessment for AD fixed‑dose syringes.
- Regulatory authorities & procurement agencies - specification for tenders and regulatory review of vaccine delivery devices.
- Testing laboratories - perform performance and safety tests (dead space, leakage, AD function, shipping robustness).
- Immunization programs & NGOs - procurement guidance to ensure safe, single‑use injection devices that prevent reuse.
Practical uses:
- Ensuring AD syringes reliably disable after one use to reduce reuse and disease transmission.
- Defining packaging and labeling to maintain sterility and support field immunization campaigns.
- Providing objective test methods for procurement acceptance and batch release.
