ISO 3826-3:2006 specifies requirements, including performance requirements, for integrated features on plastic, collapsible, non-vented, sterile containers (blood bag systems). The integrated features refer to: leucocyte filter; pre-donation sampling device; top and bottom bag; platelet storage bag; needle stick protection device. In addition to ISO 3826-1:2003, which specifies the requirements of conventional containers, ISO 3826-3:2006 specifies additional requirements for blood bag systems using multiple units. Unless otherwise specified, all tests specified in ISO 3826-3:2006 apply to the plastic container as prepared ready for use.
