Fluid lines for use with pressure infusion equipment and
accessories for single use - Part 2: Accessories
1 Scope
This part of YY 0585 specifies the physical, chemical, and biological requirements for
accessories used with pressure infusion equipment.
This part applies to accessories for single-use sterile fluid lines and accessories for
pressure infusion equipment specified in YY 0286.4, including:
a) Two-way stopcock (2SC), three-way stopcock (3SC), four-way stopcock (4SC)
and stopcocks manifold (SM);
Note: The labelling of the stopcock depends on the number of connections. The number of possible
functional positions can be indicated by the addition of a supplementary note, as expressed by a slash
and the number of possible positions of the stopcock. For example, a 3/4-way stopcock means a three-
way stopcock with 4 possible positions.
b) Units with injection sites (UIS) or units with check valves (UCV);
c) Stoppers (S) or adapters (A).

Pharmacopoeia of the People’s Republic of China
3 Materials
The materials from which accessories are manufactured shall meet the requirements
specified in Chapter 4, Chapter 5, and Chapter 6.
4 Physical requirements
4.1 Avoidance of air bubbles
All components of accessories shall be designed so that no air bubbles are detected in
flow channels when they are tested in accordance with A.1 of Appendix A.
4.2 Particulate contamination
The accessories shall be manufactured with minimal particulate contamination. Fluid
pathway surfaces shall be smooth and clean. When the test is carried out according to
A.2, the pollution index shall not be exceeded.
4.3 Connection strength
When the test is carried out in accordance with the provisions of A.3, the accessories
and the connections between all components (except the protective cover) shall be able
to withstand a static tensile force of not less than 15 N for 15 s.
For stopcocks, the connections between the plug and the housing shall be able to
withstand the tensile force regardless of the position of the plug.
4.4 Leakage
The accessories shall be impermeable to air, microorganisms and fluid. No matter where
the plug is located, it shall be sealed. When the test is carried out according to A.4, there
shall be no air or water leakage.
4.5 Adapters with female and/or male conical fittings
The adapters shall have female conical fittings and/or male conical fittings in
8.2 Single package
A single package shall be labelled with at least the following information:
a) The manufacturer’s name and address;
b) Text description of the contents, such as single-use stopcocks manifold;
c) The accessories are pyrogen-free, or the accessories are free of bacterial
endotoxins;
d) The graphic symbols given in YY/T 0466.1 are used to indicate that the
accessories are sterile;
e) Lot number that begins with the word “LOT”, or indicated by the graphic symbol
of YY/T 0466.1;
f) The expiration date (month/year) represented by the corresponding text or the
graphic symbols given in YY/T 0466.1;
g) The accessories are for single use only that is indicated by the description of the
equivalent text, or the graphic symbol conforming to YY/T 0466.1;
h) Instructions for use, including warnings, such as checking whether the protective
cap has fallen off;
i) The letter “P” that represents pressure, and the size of which shall stand out from
the surrounding text.
If the single package area is too small to give all the information and/or symbols, the
information can be simplified to e) and f). In this case, the information required by this
clause shall be given on the label of the next larger shelf or multi-unit package.
8.3 Shelf or multi-unit package
The shelf or multi-unit package shall be labelled with at least the following information:
a) The manufacturer’s name and address;
b) Text description of the contents, such as single-use stopcocks manifold;
c) Lot number that begins with the word “LOT”, or indicated by the graphic symbol
of YY/T 0466.1;
d) The expiration date (month/year) represented by the corresponding text or the
graphic symbols given in YY/T 0466.1;
e) The text “Safe for use with pressure infusion equipment”;
Appendix A
(Normative)
Physical test
A.1 Air bubbles
Fill the accessory to be tested with distilled water according to the usual operation
method, and visually check whether there are air bubbles in the fluid pathway of the
transparent components.
A.2 Particulate contamination test
The volume of the rinse fluid shall be at least 50 times the volume of the inner cavity
of the test sample, and the test shall be carried out in accordance with the provisions of
GB 8368.
A.3 Connection strength test
The accessory to be tested shall be subjected to an axial static tensile force of 15 N for
15 s. The same tensile force is also applied in the direction of the rotation axis of the
stopcock’s plug body. Inspect whether the connections of the components can withstand
the applied force.
A.4 Leakage test
A.4.1 Before starting the test, place the entire system at the test temperature for
conditioning.
A.4.2 Use the male and/or female adapters that are in accordance with GB/T 1962.2 to
seal each port of the accessory, connect it with the compressed air source, apply air
pressure of...
