Foreword
YY/T 0573 "Sterile hypodermic syringes for single use" consists of the following
parts:
- Part 2: Syringes for use with power-driven syringe pumps;
- Part 3: Auto-disable syringes for fixed dose immunization;
- Part 4: Syringes with re-use prevention feature.
This part is part 4 of YY/T 0573.
GB 15810 "Sterile syringes for single use" adopts, through modification, the ISO
7886-1 "Sterile hypodermic syringes for single use - Part 1: Syringes for manual
use". Therefore, the standard series of YY/T 0573 "Sterile hypodermic syringes
for single use" does not have part 1.
This part was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces YY 0573.4-2010 "Sterile hypodermic syringes for single use
- Part 4: Syringes with re-use prevention feature".
Compared with YY 0573.4-2010, the main technical changes in this part are as
follows:
- INTRODUCE the content of 15.4 "Performance after shipment" into 8.3
"Large package" (see 8.3);
- ADD the requirements for easy oxides and ethylene oxide residues, in the
chemical requirements (see 6.3, 6.4);
- ADD the requirements for sterility and bacterial endotoxins, in the biological
requirements (see 7.2, 7.3);
- MODIFY the requirements of "initial packaging or self-sealing packaging"
(see 8.1; Chapter 16 of the 2010 edition);
- ADD the Appendix A "Test methods for capacity tolerance and residual
capacity" (see Appendix A);
- ADD the Appendix B "Test method for leakage at the connection of the fixed
needle tube and the needle seat, at the piston or seal ring, when the syringe
is under positive pressure" (see Appendix B);
- ADD the Appendix C "Test method for leakage, at piston or sealing ring
AND separation of piston and core rod, when syringe is pumped under
negative pressure" (see Appendix C);
- ADD the Appendix D "Test method for fit between jacket and piston
assembly" (see Appendix D);
- ADD F.2 "Test method for residual ethylene oxide" (see Appendix F);
- ADD the Appendix G "Guidelines for design and materials" (see Appendix
G);
- DELETE the Appendix C "Environmental aspects" of the original standard
(see Appendix C of the 2010 edition).
This part uses the redrafting method to modify and adopt ISO 7886-4:2006
"Sterile hypodermic syringes for single use - Part 4: Syringes with re-use
prevention feature"
The technical differences between this part and ISO 7886-4:2006, as well as
the reasons, are as follows:
- Regarding normative references, this part has made adjustments with
technical differences, to adapt to China's technical conditions. The
adjustments are specifically reflected in Chapter 2 "Normative references";
the specific adjustments are as follows:
● DELETE the ISO 7000;
● DELETE the ASTM D999-01;
● DELETE the ASTM D5276-98;
● USE the GB/T 6682-2008, which modifies and adopts the international
standard, to replace ISO 3696:1987;
● USE the GB 15811-2016, which non-equivalently adopts the
international standard, to replace ISO 7864:1993 (see 5.6.2);
● USE the GB/T 18457-2015, which modifies and adopts the
international standard, to replace ISO 9626 (see 5.6.2);
● USE the GB/T 191-2008, which modifies and adopts the international
standard, to replace ISO 780 (see 9.1);
● USE the GB 15810, which modifies and adopts the international
standard, to replace ISO 7886-1:1993 (see Chapter 3);
● USE the YY/T 0497, which modifies and adopts the international
standard, to replace ISO 8537:1991 (see Chapter 3);
Sterile hypodermic syringes for single use - Part 4:
Syringes with re-use prevention feature
1 Scope
This part of YY/T 0573 specifies the terms and definitions, naming and
classification, physical requirements, chemical requirements, biological
requirements, packaging, markings, etc. of sterile hypodermic syringes for
single use (hereinafter referred to as syringes) with re-use prevention features.
This part applies to sterile hypodermic syringes for single use, which are made
of plastic materials, with or without needles, used for aspirating liquids OR for
injection immediately after aspirating liquids, designed to prevent re-use. It is
suitable for the re-use prevention performance of syringe, which can prevent
accidental needle stick injury. This part does not involve the performance of
preventing accidental needle stick injury of this type of syringe.
This part does not apply to glass syringes, self-destructive fixed-dose vaccine
syringes, syringes with prefilled liquid medicine. This part does not involve the
compatibility of the syringe and the injection liquid.
This part does not specify the design requirements for self-destructive features.
Note: When the syringe is used beyond the intended use, which is specified in this part,
other standards apply.
