ISO 11040-4:2015 applies to tubing-glass barrels (single-chamber design) for injection preparations, and sterilized subassembled syringes ready for filling. It specifies materials, dimensions, quality, and performance requirements, as well as relevant test methods. ISO 11040-4:2015 also specifies those components that are part of the sterilized subassembled syringe ready for filling. Glass barrels and sterilized subassembled syringes ready for filling in accordance with ISO 11040-4:2015 are intended for single use only. Components to complete the subassembled syringe, such as plunger and rod, are not specified in ISO 11040‑4:2015.
