ISO 3826-3:2006

Overview

ISO 3826-3:2006 defines requirements and performance criteria for plastic, collapsible, non‑vented, sterile blood bag systems that include integrated features. It is a specialized part of the ISO 3826 series and supplements ISO 3826-1:2003 (conventional containers). ISO 3826-3 covers systems that may incorporate one or more integrated features such as leucocyte filters, pre‑donation sampling devices (PDS), top‑and‑bottom (TBB) bags, platelet storage bags (PSB) and needle‑stick protection devices (NPD). Tests apply to containers “ready for use.” The standard does not apply to automated blood collection systems and national regulations or pharmacopoeias take precedence where applicable.

Key topics and technical requirements

• Scope and definitions for integrated features: LCF, PDS, TBB, PSB, NPD.
• Performance and design expectations in addition to ISO 3826-1:
  • Leucocyte filter (LCF): May be designed for gravity or pressure filtration and for operation at 4 °C or ambient temperature. Manufacturers must state recommended delay to filtration, filter capacity, operating temperature, filtration height, pressure use and suitability for centrifugation.
  • Pre‑donation sampling device (PDS): If a pouch is included, minimum capacity is 35 ml; device must achieve a mean fill flow rate of at least 50 ml/min (tested per ISO 3826-1). Mechanisms must prevent backflow of blood/air toward the donor.
  • Top‑and‑bottom bag (TBB): Designed for centrifugation separation (plasma via top outlet; red cells via bottom outlet). May be used with automatic press systems.
  • Platelet storage bag (PSB): Requires suitable gas permeability (O2/CO2) and container characteristics to support platelet storage under controlled temperature and continuous agitation; storability assessed by measures such as pH, hypotonic shock response and platelet aggregation.
  • Needle‑stick protection device (NPD): Integrated housing for donor needle with recommendations for safe use; may be subject to national rules.
• General requirements cover sterilization, physical integrity, impermeability to microorganisms (filter housing), particulate contamination, chemical/biological compatibility, packaging, labelling and shelf life - cross‑referenced to ISO 3826-1 test methods.

Applications and users

• Intended for blood bag manufacturers, medical device designers, suppliers of transfusion consumables, and contract manufacturers who develop integrated blood bag systems.
• Useful for blood banks, transfusion services, procurement officers and regulatory/quality teams to evaluate product compliance and to prepare submission dossiers.
• Helps clinicians and hospital transfusion services understand the functional expectations for integrated features (e.g., leucoreduction, sampling, platelet storage).

Related standards and notes

• Normative reference: ISO 3826-1:2003 (Plastics collapsible containers - Part 1: Conventional containers).
• Part 2 (graphical symbols) was in preparation at time of publication.
• National pharmacopoeias and regulatory standards may impose additional or overriding requirements.
