ISO 8536-9:2015

Overview

ISO 8536-9:2015 specifies requirements for sterilized fluid lines for single use designed to be used with pressure infusion equipment up to a maximum of 200 kPa (2 bar). It covers three product types: syringe pump lines (SPL), connecting lines (CL) and lines with integrated injection cannula (LIC). The standard is part of the ISO 8536 series on infusion equipment and focuses on safety, performance, labelling and testing for disposable pressure-fed fluid lines.

Key topics and technical requirements

• Scope and product types: Applies to single-use, sterilized fluid lines for pressure infusion (SPL, CL, LIC).
• Physical requirements:
  • Transparency: tubing must be transparent so an air–water interface is detectable (A.1).
  • Particulate contamination: manufactured to minimize particles; particle counts must not exceed defined contamination index (A.2).
  • Tensile strength: all parts must resist a static tensile force of at least 15 N for 15 s (A.3).
  • Leakage: fluid lines must be impermeable to air, microorganisms and fluids (A.4).
  • Adapters: conical fittings must conform to ISO 594-2 (Luer lock).
  • Storage volume / bolus volume: storage volume (filling + bolus) must be determined and declared (Annex C).
• Chemical and biological requirements:
  • Materials must meet chemical tests (Annex B) and biological safety including validated sterilization, freedom from pyrogens, and absence of haemolytic constituents (ISO 10993-4 referenced).
• Accessories and filters: accessories (except infusion filters) conform to ISO 8536-10; infusion filters to ISO 8536-11.
• Packaging and labelling:
  • Unit containers must carry manufacturer, contents description, sterility and pyrogen statements, lot number, expiry date, single‑use indication, instructions, storage volume, and the letter “P” for pressure (9.2).
• Disposal: guidance for secure and environmentally sound disposal of single‑use infusion sets is required.

Practical applications / who uses this standard

• Medical device manufacturers - design, test and certify single‑use pressure fluid lines for regulatory submissions and market access.
• Quality and regulatory teams - ensure compliance with physical, chemical and biological requirements and labelling rules.
• Test laboratories - perform the normative physical, chemical and sterility tests referenced in the standard’s annexes.
• Procurement and clinical engineers - select compatible, compliant pressure infusion lines (SPL, CL, LIC) for hospitals and infusion systems.
• Clinicians and risk managers - understand bolus/storage volume implications and safety limits for pressure infusion.
