Overview
EN ISO 10555-3:2013 is an international standard specifying the requirements for sterile, single-use central venous catheters. Developed by ISO/TC 84 and coordinated with CEN, this standard ensures that central venous catheters (CVCs) meet strict safety, performance, and usability criteria, supporting healthcare providers in delivering safe intravascular access.
Central venous catheters are essential medical devices designed for vascular access in various clinical settings, including administration of medications, fluids, blood sampling, and hemodynamic monitoring. This standard applies specifically to CVCs supplied in sterile condition for single use only, underlining the importance of maintaining sterility and preventing cross-contamination.
Key Topics
1. Scope and Definitions
- Specifies requirements for central venous catheters intended for the central venous system.
- Covers single- or multi-lumen catheters, which may incorporate a fixation system.
- Emphasizes single-use, sterile catheters to minimize infection risks.
2. Design and Markings
- Distance Markings: If present, these markings must indicate distance from the catheter's distal end, with intervals not exceeding 5 cm. Recommended marking intervals of 1 cm assist in accurate placement and monitoring of catheter migration.
- Lumen Identification: Multi-lumen catheters must clearly identify each lumen, facilitating safe and precise usage.
3. Performance Requirements
- Peak Tensile Force: Specifies minimum tensile force for catheter tips, especially those made from softer materials or constructed differently from the shaft, ensuring mechanical stability and preventing tip detachment during use.
- Compliance with performance parameters outlined in ISO 10555-1 except for specific tensile force requirements unique to this part.
4. Manufacturer Information
- Manufacturers must provide detailed product information including:
- Description of distance marking system (if applicable)
- Flow rate for each lumen to inform clinical usage
- Maximum guidewire diameter compatible with the catheter
- Warnings against unsafe catheter manipulations (e.g., withdrawing catheter back through the needle)
- Recommended cleaning agents, even though catheters are intended for single use, supporting best practice for device handling.
Applications
EN ISO 10555-3:2013 central venous catheters are critical in various clinical procedures such as:
- Administration of intravenous therapies including chemotherapy, antibiotics, and parenteral nutrition.
- Central venous pressure monitoring and hemodynamic assessment.
- Long-term vascular access for critically ill patients or those requiring frequent blood sampling.
- Emergency interventions and dialysis access.
Adherence to this standard ensures these catheters provide reliable performance while minimizing risks such as infection, thrombosis, and mechanical failure – paramount in intensive care units, oncology wards, and surgical settings.

Summary
EN ISO 10555-3:2013 standardizes the design, performance, and user information for sterile, single-use central venous catheters, enhancing patient safety and clinical efficacy. It supports compliance with EU directives governing medical devices, fostering harmonized quality and regulatory alignment across member states. Healthcare providers and manufacturers benefit from its comprehensive guidance to optimize central venous catheter use in diverse medical interventions.
