Containers covered in this part of ISO 11608 include single- and multi-dose syringe-based and cartridge-based systems, flled either by the manufacturer or by the end-user. Additional guidance for NISs equipped with electronic or electromechanical components and NISs equipped with automated functions is given in ISO 11608-4 and ISO 11608-5 respectively. Needle-free injectors, and requirements relating to methods or equipment associated with end-user flling of containers, are outside the scope of this part of ISO 11608.
