Overview
EN ISO 3826-4:2015 - Plastics collapsible containers for human blood and blood components, Part 4 - specifies requirements and performance criteria for aphaeresis blood bag systems with integrated features. Published by CEN and identical to ISO 3826-4:2015, this standard covers design, physical, chemical and biological requirements for collapsible plastic blood bags used to collect and store blood components by apheresis. It applies to systems used on automated or semi-automated blood collection equipment and recognizes that not every aphaeresis bag system must include all listed integrated features.
Key Topics and Technical Requirements
- Scope of integrated features: needle stick protection device, leucocyte filter, sterile barrier filter, pre-collection and post-collection sampling devices, collection/transfer tubing and outlet ports, storage bags for red blood cells, plasma, platelets, polymorphonuclear/stem cells, and connections for storage solutions, anticoagulant and replacement fluids.
- Design and dimensions: standardizes bag and connector geometries, suspension points and arrangement of integrated components to support safe apheresis operations.
- Physical requirements: addresses sterilization, transparency, coloration, thermal stability, water vapour transmission (for prefilled bags), resistance to leakage, insertion/pull forces and particulate contamination.
- Chemical and biological safety: defines requirements for materials (raw container/sheeting) and test fluids and refers to biological evaluation standards (EN ISO 10993 series) for cytotoxicity, sensitization and other biocompatibility assessments.
- Performance testing: includes mechanical stress/resistance checks, leakage tests after piercing/closure and criteria linked to safe blood collection and storage.
- Regulatory alignment: Annex ZA maps clauses to Essential Requirements of EU Directive 93/42/EEC (Medical Devices), supporting conformity assessment when used within the directive’s scope.
Practical Applications and Users
- Medical device manufacturers designing or producing apheresis blood bag systems and integrated components.
- Blood centers and transfusion services specifying procurement requirements for aphaeresis collection sets.
- Quality, regulatory and compliance teams documenting conformity with EU medical device requirements and ISO quality systems.
- Testing and certification laboratories performing sterility, leakage and biocompatibility testing on blood bag systems.
- R&D teams developing new integrated features (e.g., needle-stick protection, filtration) for apheresis workflows.
Related Standards
EN ISO 3826-4:2015 is essential for stakeholders who design, procure or regulate apheresis blood bag systems, ensuring safety, compatibility with automated collection systems, and alignment with medical device regulatory frameworks.
