Overview
EN ISO 8536-16:2025 (ISO 8536-16:2025) specifies requirements for sterilized, single-use, gravity-feed infusion sets designed to be used with volumetric infusion controllers (see IEC 60601-2-24). The standard covers design elements, materials, performance and safety tests, labelling, packaging and disposal considerations for infusion sets intended for medical use. It addresses sets used with both rigid and collapsible containers and defines key components such as flow elements, drip chambers, tubing and air-inlet devices.
Key topics and technical requirements
The standard defines technical requirements across several domains:
-
General design and components
- Required parts (e.g., closure-piercing device, air-inlet with filter, drip chamber, fluid filter, tubing, flow regulator, flow element, injection site, male conical fitting).
- Configurations for rigid vs. collapsible fluid containers.
-
Materials and chemical/biological safety
- Material selection and compatibility for sterilized, single-use devices.
- Chemical and biological requirements to protect patient safety (biocompatibility and sterility).
-
Physical performance tests
- Tests and acceptance criteria for particulate contamination, leakage, tensile resistance, flow rate and flow regulator performance.
- Requirements for closure-piercing devices, air-inlet devices, tubing integrity, fluid filters and drip-chamber behaviour.
- Annex A contains normative physical test methods.
-
Labelling, packaging and disposal
- Unit and multi-unit container labelling requirements, use of standardized symbols (ISO 15223‑1, ISO 7000).
- Packaging to maintain sterility and instructions for safe disposal of single-use infusion sets.
-
Terminology and scope
- Definitions (e.g., volumetric infusion controller, flow element, lifetime) to ensure consistent interpretation.
Applications and who uses this standard
EN ISO 8536-16:2025 is intended for:
- Manufacturers of infusion sets and accessories designing single-use, gravity-feed sets compatible with volumetric infusion controllers.
- Medical device engineers and product development teams ensuring device interoperability and regulatory compliance.
- Quality assurance, regulatory and conformity assessment bodies assessing performance, safety and labelling.
- Clinical procurement and biomedical departments evaluating devices for hospital use.
- Testing laboratories performing the normative physical and biological tests.
Adoption supports safe, compatible infusion therapy solutions, reduces risk of device failure, and helps manufacturers meet European and international regulatory expectations.
