All technical content of this Standard is mandatory.
This Standard was drafted in accordance with the rules given in GB/T
This Standard replaces GB 15811-2001 Sterile hypodermic needles for single
use. Compared with GB 15811-2001, the main technical changes are as
- added Clause 5 “Materials”;
- added Annex A Injection needle flow test device schematic;
- provided needle puncture force requirements in Annex B (informative)
Needle puncture needle requirements and test methods;
- deleted 4.3.1 Needle tube rigidity, 4.3.2 Needle tube toughness and
4.3.3 Needle tube corrosion resistance terms;
- added requirements that paper dialysis packaging materials shall be
used for primary packaging;
- modified Annex D Inspection rules.
This Standard uses redrafting method to modify and adopt ISO 7864.1993
Sterile hypodermic needles for single use. The consistency with ISO 7864.
1993 is not equivalent.
Attention is drawn to the possibility that some of the elements of this Standard
may be the subject of patent rights. The issuing authority shall not be held
responsible for identifying any or all such patent rights.
This Standard was proposed by China Food and Drug Administration.
This Standard shall be under the jurisdiction of National Technical Committee
on Medical Syringes (Needles) of Standardization Administration of China
(SAC/TC 95).

Sterile hypodermic needles for single use
1 Scope
This Standard specifies the requirements for sterile hypodermic needles for
single use of which the nominal outer diameters of needle tube are 0.3mm ~
1.2mm (hereinafter referred to as syringe needles).
The syringe needles specified in this Standard shall be matched with sterile
hypodermic needles for single use of GB 15810. They are also suitable for
other appropriate injection equipment, as human skin, subcutaneous, muscle,
vein and other liquid injections.
This Standard is not applicable to disposable dental needles.
The sterile hypodermic needles for single use of disposable sterile syringes in
non-sterile state shall refer to this Standard.

4 Marking example
4.1 The mark (specification) of the syringe needle product is composed of
the nominal outer diameter of the needle tube, the nominal length (L in Figure
1), the tube wall type and the first bevel angle (α). The outer diameter and
length are expressed in "mm", the tube wall type in RW (normal wall), TW
(thin wall) or ETW (extra thin wall), the first bevel angle in LB (long bevel
angle) or SB (short bevel angle).
4.2 The syringe needle that complies with this Standard of which the
nominal outer diameter of needle tube is 0.7 mm, the length (L) is 30 mm, the
tube wall type is thin wall, the first bevel angle is a long bevel angle shall be
Syringe needle rotates at an
angle of Φ
The view shows the difference
when the first bevel crosses the tip
marked as. 0.7 × 30 TWLB.
5 Materials
5.1 Tubes for the manufacture of injection needles shall meet the
requirements of GB/T 18457-2015.
NOTE. Each production lot of needles shall have information on rigidity, toughness and
corrosion resistance.
5.2 The materials used to make the needle seat shall meet the
requirements of Clause 7 and Clause 8.
6 Physical properties
6.1 Cleanness
In 300lx ~ 700lx illumination, with normal or corrected vision, without
amplification, observe the needle tube; and under 2.5 times magnification,
observe the needle seat surface that shall be clean, without foreign matters.
6.2 Color code
The syringe needle shall use the colors of needle seat and/or jacket as the
mark of nominal outer diameter of needle tube in according to the
requirements of YY/T 0296.
6.3 Uprightness
Visually observe the connection of needle seat and needle tube that shall be
upright. The needle tube shall not be obviously skewed.
6.4 Connection fastness
The connection between needle seat and needle tube shall be solid. Fix the
syringe needle tube on a special instrument. Use needle seat to allocate
direction and carry out the impact-free pull-off test under the load specified in
Table 1. Both must not be loose or separated.
Table 1 -- Load of pull-off test
Table 1 (continued)
6.5 Smoothness
The pinhole of syringe needle shall be smooth.
a) the tip cleaner specified in Table 2 shall be able to pass through freely;
b) or under a water pressure not greater than 100 kPa, the flow shall not be
less than 80% of minimum inner diameter syringe flo...
