Plunger seal of syringes for single use
1 Scope
This standard specifies the terminology and definition, classification and
marking, requirements, type inspection, packaging, marking, transportation and
storage of plunger seal of syringes for single use (hereinafter referred to as
plunger).
This standard applies to plungers for single-use syringes. The plunger can be
used for disposable sterile syringes and disposable sterile insulin syringes, but
it is not suitable for syringes with prefilled liquids and syringes matching for
liquids.

5.1.7 The yellowing resistance test is carried out in accordance with the test
method of Appendix B. Under the condition of aging at 70 °C for 14 days, the
color of the plunger before and after aging shall not change significantly.
5.2 Physical and mechanical properties of material
5.2.1 Hardness (shore A)
When tested in accordance with the method specified in GB/T 531.1, it shall
comply with the hardness agreed by the manufacturer of the plunger or the
manufacturer of the syringe for single use. The deviation shall not exceed the
nominal value ±5. Unspecified hardness shall meet 60+5/-3.
5.2.2 Compression set
When tested in accordance with the method specified in GB/T 7759.1, the aging
test is carried out at 40 ± 1 °C and 120+0/-2 h. The compression set of the
plunger shall not exceed 40%.
Note. Appendix C gives the test method for the permanent compression of the
finished plunger.
5.2.3 Change rate in tensile strength
When tested in accordance with the method specified in GB/T 3512, after aging
at 70°C for 72 hours, the change rate of tensile strength of the plunger before
and after aging shall not exceed ±20%.
5.2.4 Change rate in elongation at break
When tested in accordance with the method specified in GB/T 3512, after aging
at 70°C for 72 hours, the change rate of elongation at break of the plunger
before and after aging shall not exceed ±20%.
5.3 Chemical properties
5.3.1 pH
When measuring with a laboratory pH meter and a universal electrode, the
difference between the pH of the extract prepared in accordance with Appendix
D and the pH of the blank shall not exceed 1.0.
5.3.2 Extractable metal content
The extract prepared in accordance with Appendix D is tested using approved
microanalytical methods (e.g., atomic absorption method). The sum of the
Appendix A
(Informative)
Material guide
The material used to make the plunger shall be compatible with the sterilization
process of a suitable syringe.
The material used to make the plunger shall not have a physical or chemical or
other deleterious effect during the routine use of an injection by a suitable
syringe.
The material used to make the plunger uses a high quality natural or synthetic
rubber polymer. The content of rubber shall not be less than 40%. It can be
tested in accordance with clause 4.4 “Rubber polymer content” or clause 5 “Test
of rubber polymer” in GB/T 7766-2008. The distinction between natural rubber
and non-natural rubber can be determined in accordance with the test method
of “Nitrogen content by protein” in clause 4.10.7 of GB/T 7766-2008.
This standard does not limit the progress of technology. If thermoplastic
elastomers or other polymer materials are used, manufacturers should make
reference to this standard and relevant standards and regulations for evaluation.
The surface of the plunger can optionally use dimethyl silicone oil as a lubricant
in accordance with the Chinese National Pharmacopoeia.
The plunger shall not release any substances that have side effects on the
human body. When the new product is put into production, materials and
production processes have major changes, they shall be evaluated biologically
in accordance with GB/T 16886.1. The basic evaluation test is.
