Overview
EN ISO 8536-15:2022 - Infusion equipment for medical use - Part 15: Light-protective infusion sets for single use specifies requirements and test methods for infusion sets that incorporate light‑protective agents in the fluid‑path materials. This European adoption of ISO 8536-15:2022 applies to single‑use infusion sets intended to protect light‑sensitive pharmaceuticals (e.g., nitroprusside, nitroglycerin, riboflavin) and provides guidance on performance, materials, labelling, packaging and disposal.
Key topics and technical requirements
- Scope: Applies to infusion sets for single use that use light‑protective materials in the fluid path.
- Light‑transmittance: Measured across the 290–450 nm wavelength range (Annex A). Component limits:
- Drip chamber ≤ 35% transmittance
- Tube ≤ 15% transmittance
- Transparency/visibility: Tubing must remain transparent or translucent enough to permit observation of the air–liquid interface and bubbles; the upper part of drip chambers must allow droplet observation (refer ISO 8536-4).
- Decolourization testing: Ensures the light‑protective agent does not leach or change color
- Outer surfaces: Test by physical method (Annex B)
- Inner surfaces: Test by chemical visual colorimetry (Annex C)
- Materials and safety: Materials must meet the chemical and biological requirements of ISO 8536-4, including biocompatibility and chemical compatibility.
- Labelling and instructions:
- Product must be labelled “Light‑protective set” (or translation).
- Labelling must include the wavelength spectrum for which the transmittance limits apply.
- Instructions for use should warn about infusion length and ambient lighting effects and refer to the pharmaceutical monograph.
- Packaging & disposal: Follow ISO 8536-4 packaging rules; include guidance for secure and environmentally sound disposal.
Practical applications
EN ISO 8536-15:2022 is used to design, test and certify infusion sets that protect light‑sensitive drugs during administration. It enables:
- Consistent manufacturing controls for light‑protective infusion sets
- Objective test methods for quality assurance and regulatory submissions
- Clear labelling so clinicians select appropriate sets for light‑sensitive infusions
- Risk reduction for drug degradation due to light exposure
Who should use this standard
- Medical device manufacturers (R&D, product development, QA)
- Regulatory and conformity assessment bodies
- Test laboratories performing light transmittance and decolourization tests
- Hospital procurement, clinical engineering and pharmacy teams selecting infusion equipment
Related standards
- ISO 8536 series (other parts referenced for physical, chemical and biological requirements)
- ISO 8536-4 (specific chemical and biological requirements, labelling and packaging references)
