Introduction
As a single device, sterile syringes for single use needs to be combined with sterile injection needle for single use for clinical application.
This standard encourages the manufacturers to treat the syringe together with the supporting injection needle as sales units, the structures and terms related to injection needles have therefore been added into the "syringe illustration".
Considering that syringes without injection needles shall not be restricted, syringes without injection needles specified in this standard shall be used in conjunction with the sterile injection needles for single use meeting those specified in GB 15811.
If the syringe itself is equipped with an injection needle, the chemical and biological properties shall be tested with the extract prepared with the injection needle mounted on the syringe.
ISO 594-1: 1986 corresponding to GB/T 1962.1-2015 and ISO 594-2: 1998 corresponding to GB/T 1962.2-2001 have been replaced by ISO 80369-7: 2006, and the corresponding professional standard converted is YY/T 0916.7 (under approval).
