Test methods for particle contamination of infusion,
transfusion and injection equipment for medical use
1 Scope
This Standard specifies test methods for particle contamination of intravenous
infusion, blood transfusion, injection equipment.
This Standard is applicable to particle contamination inspection of intravenous
infusion device. For other products, the particle contamination test method can
refer to this Standard.
This Standard is not applicable to syringe for intramuscular injection with a
nominal capacity of 1 mL or less.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.
GB/T 6682-2008, Water for analytical laboratory use - Specification and test
methods (ISO 3696:1987, MOD)
GB/T 25915.1-2010, Cleanrooms and associated controlled environments -
Part 1: Classification of air cleanliness (ISO 14644-1:1999, IDT)
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1 fluids for washing
liquids that have not been contacted with test sample and are used to elute
particles contained in the test sample
3.2 fluids after washing
liquids that after the fluids for washing are in contact with the test sample, the
particles contained in the sample have been eluted into the fluid for washing
6 Principle
Choose the right fluids for washing. Rinse the test piece by the specified method.
Classify and count the particles in the fluids after washing (3.2) by a suitable
counting method.
7 Instruments and materials
7.1 Fluids for washing
7.1.1 Fluid A for washing: purified water, filtered through a membrane with a
pore size of not more than 0.22μm.
7.1.2 Fluid B for washing: isopropanol, analytically pure, filtered through a
membrane of no more than 0.22μm.
7.1.3 Fluid C for washing: Tween-80 solution, 3g of commercially available high
concentration polysorbate 80 (Tween-80) is dissolved in 10L of pure water (in
accordance with GB/T 6682-2008 level 1 or 2).
7.2 Vacuum filter
The aperture is 0.45μm.
7.3 Erlenmeyer flask
The volume is 300mL.
7.4 Ultrasonic cleaner
The frequency is 40kHz.
7.5 Oscillating device
Move at a frequency of 300 times/min ~ 350 times/min on a horizontal circular
path with a diameter of 12mm ± 1mm.
7.6 Particle counter
It uses extinction (light shading or light blocking) principle. And it can classify
and count particles in the fluids after washing according to the categories
defined in Table 1.
7.7 Microscope
Magnification is about 50 times, with proper direct illumination of 0°~10° with
the microscope stage.
after washing to obtain at least 100mL of collected fluid.
10.3.2 For syringes with a nominal capacity greater than 10mL and less than or
equal to 100mL, take 5 syringes. Respectively extract the fluids for washing of
half nominal capacity. Pull the piston to the nominal capacity. Oscillate on the
oscillating device (7.5) for 20s. Bring the fluids after washing from each syringe
together. If the fluids after washing is less than 100 mL, repeat the above steps
for the same 5 syringes. Combine the obtained fluids after washing to obtain at
least 100mL of collected fluid.
10.3.3 For test syringes with a nominal capacity greater than 100mL, take 3
syringes. Respectively extract 100mL of fluids for washing. Move the piston to
the nominal capacity. Place the cone head on the oscillating device (7.5) and
oscillate for 20s to obtain 3 portions of 100mL unit washing fluid.
10.4 Containers
Take 3 containers for supply. Respectively fill the fluids for washing of nominal
capacity through the filling tubing. Close container. Use ultrasonic cleaner to
elute 2min. Collect the fluids after washing into the sampling cup to obtain 3
portions of unit washing fluid of test sample’s nominal capacity.
10.5 Small entries
Take 10 test products. Place them in an Erlenmeyer flask (7.3). Add into 100mL
of fluids for washing. Cover the top of the conical bottle with aluminum foil (or
other suitable material). Place in an oscillating device (7.5) to oscillate for 20s
to obtain 100mL of collected fluid.
10.6 Piercing devices
Take 5 test sample......
