Overview
EN ISO 8536-9:2015 - Infusion equipment for medical use - Part 9: Fluid lines for single use with pressure infusion equipment (ISO 8536-9:2015) specifies requirements for sterilized, single‑use fluid lines intended for use with pressure infusion equipment up to a maximum of 200 kPa (2 bar). The standard covers three product types: syringe pump lines (SPL), connecting lines (CL) and lines with integrated injection cannula (LIC). It is published by CEN/ISO and aligns with European medical device system requirements.
Key topics and technical requirements
The standard addresses design, safety and performance aspects relevant to single‑use pressure infusion tubing, including:
- Scope and classification - defines device types (SPL, CL, LIC) and the maximum working pressure (200 kPa / 2 bar).
- Materials - biocompatibility and material selection for medical fluid contact.
- Physical requirements:
- Transparency and visual inspection for flow and particulates.
- Particulate contamination limits.
- Tensile strength and mechanical integrity under stress.
- Leakage and adapter sealing (conical fittings).
- Filters, injection needles, protective caps and accessory compatibility.
- Storage volume specifications (normative Annex C).
- Chemical requirements - extraction/chemical compatibility tests (see normative Annex B).
- Biological requirements - sterility, pyrogen control and haemolysis considerations; sterilization methods and validation are referenced.
- Packaging and labelling - requirements for unit and multi‑unit containers, traceability and symbol use (includes guidance on ISO 7000 symbols).
- Disposal - recommendations for safe disposal of single‑use fluid lines.
- Normative tests - physical, chemical and biological tests are specified in Annexes A–C.
Practical applications and users
EN ISO 8536-9:2015 is used by stakeholders involved in the design, manufacture, regulation and clinical use of pressure infusion tubing:
- Medical device manufacturers - to design and validate single‑use fluid lines for pressure infusion systems and ensure conformity with harmonized standards.
- Quality and regulatory teams - to demonstrate compliance with CE marking and directives relevant to infusion devices.
- Clinical engineers and procurement - to specify compliant tubing for emergency, operating room and transfusion/infusion therapy where pressure infusion is required.
- Hospitals and clinicians - to understand performance and safety expectations for single‑use pressure infusion lines.
