SIST EN ISO 7886-4:2019 PDF

Overview

EN ISO 7886-4:2019 (ISO 7886-4:2018) specifies requirements for sterile hypodermic syringes for single use that include a re‑use prevention feature. Endorsed by CEN, this European adoption of the ISO standard covers plastic and rubber syringes, with or without integrated needles, intended for aspiration or immediate injection after filling and designed to be rendered unusable after one use. The standard supports regulatory compliance in the EU (see informative Annex ZA) and supersedes the 2009 edition.

Key topics and technical requirements

This standard addresses the design, testing and information requirements necessary to demonstrate safe single use and effective re‑use prevention. Key technical topics include:

• Types of syringe and re‑use prevention features - classification of intended designs and mechanisms that prevent re‑use.
• Materials and cleanliness - limits for extraneous matter, acidity/alkalinity and extractable metals.
• Lubricant and assembly - requirements affecting plunger performance and user feel.
• Graduated scale and capacity tolerance - marking, scale position and dimensional tolerances on nominal capacity.
• Barrel, plunger and nozzle/needle interfaces - dimensional and fit requirements for safe operation.
• Performance tests - dead space measurement, freedom from air and liquid leakage, verification of the re‑use prevention feature, and performance after shipping.
• Packaging and labeling - unit and multiple unit pack requirements, transport wrapping and information supplied by the manufacturer.
• Normative test methods - Annex A (preparation of extracts) and Annex B (test method for re‑use prevention feature) provide standardized test procedures.

Note: the standard does not apply to glass syringes (ISO 595 withdrawn), auto‑disable syringes for fixed‑dose immunization (ISO 7886‑3), or pre‑filled syringes. Compatibility with injection fluids and anti‑needle‑stick properties are not addressed.

Applications

EN ISO 7886-4:2019 is used to:

• Develop and validate single‑use syringe designs with built‑in re‑use prevention.
• Define quality control and incoming inspection criteria for syringe production.
• Create regulatory and procurement specifications for hospitals, public health programs and medical device distributors.
• Provide standardized test methods for conformity assessment and certification, including support for CE marking in Europe.

Who should use this standard

• Medical device manufacturers and product designers
• Quality assurance and regulatory affairs professionals
• Test laboratories and conformity assessment bodies
• Hospital procurement and infection‑control teams
• Public health organizations seeking to limit unsafe syringe reuse

Related standards
