Plasticized poly(vinyl chloride) compounds for
transfusion (infusion) equipment
1 Scope
This standard specifies the requirements, test methods, markings, packaging,
transportation, storage of plasticized poly(vinyl chloride) compounds for
transfusion (infusion) equipment.
This standard applies to the PVC plastics for disposable transfusion (infusion)
bags, transfusion (infusion) catheters, accessories, which are made through
blending and modifying the main material of polyvinyl chloride resin, by adding
other necessary additives such as bis(2-ethylhexyl) phthalate (DEHP)
plasticizer, epoxy soybean oil and/or epoxy linseed oil.

3 Requirements
3.1 Material requirements
It shall control the raw materials used in production. It shall not artificially add
the substances, that have been prohibited in the relevant regulations and
instructions AND have not been toxicologically evaluated. Any changes in the
material formula shall be approved by the user AND subject to related
verification.
Note: The recognition that bis(2-ethylhexyl) phthalate (DEHP) plasticizers have
reproductive toxicity risks is widely accepted. The application of non-DEHP
plasticized PVC plastics has become a trend. Pellets manufacturers and
medical device manufacturers should conduct risk assessments, on the safety
of materials and devices, based on their end use. For information about non-
phthalic plasticizers and non-phthalic PVC plastics, see Appendix A.
3.2 Appearance
It is in natural transparent or natural translucent particles, in uniform color,
without charred particles, foreign impurities. For special colors, it can be
determined, through negotiation between the user and the manufacturer.

soluble matter
4.4.1.1 Preparation of test solution for PVC plastic water-soluble matter
Take the uniform part of sheet specimen, which has a total surface area
(including the two surfaces of the plastic sheet) of 600 cm2 [when the sample is
PVC plastic for blood bags, the total surface area is 1200 cm2], AND a thickness
of (0.45 ± 0.05) mm. Use soapy water, tap water, laboratory grade 2 water to
wash it clean. Dry it naturally. Cut into pieces of 1 cm2. Then according to the
ratio of 2:1 between specimen (cm2) and water (mL) [for the PVC plastic for
blood bags, the ratio between specimen (cm2) and water (mL) is 6:1], immerse
in a 500 mL glass container. Use an appropriate method to seal it. Place it in a
pressure steam sterilizer. Extract for 20 minutes under saturated steam at (121
± 2) °C (for the PVC plastic sample for blood bags, extract for 30 min). After
heating, separate the sample from the liquid. Cool it to room temperature, as
the test solution. The water used for the preparation of the test solution shall be
laboratory grade 2 water.
4.4.1.2 Preparation of blank control solution
Use the same batch of laboratory grade 2 water, without adding the test piece,
to operate at the same time, to prepare a blank control solution.
4.4.1.3 Determination of reducing substances
It is performed according to the requirements for indirect titration of 5.2.2 in
GB/T 14233.1-2008.
4.4.1.4 Determination of pH
It is performed according to the requirements of 5.4.1 in GB/T 14233.1-2008.
4.4.1.5 Determination of color
Take 50 mL each of the test solution and the blank control solution. Respectively
place them in a Nessler colorimetric tube. Use a white object as a background.
Under a fluorescent lamp, use normal or corrected vision, to make comparison
observation with the blank control solution.
4.4.1.6 Determination of UV absorption
According to 5.7 of GB/T 14233.1-2008, within 5 h, use a 1 cm absorption cell,
to measure the peak value of the ultraviolet light absorption peak, in the
wavelength range of 230 nm ~ 360 nm.

temperature water tank, which has reached the constant temperature of (50 ±
0.5) °C. Soak it for 2 h ± 20 s.
C.3.5 After taking out the specimen from the constant temperature water tank,
immediately put it into water at room temperature. Take it out after 5 min. Wipe
off the water. Accurately weigh it within 2 min ± 20 s (C), accurate to 0.1 mg.
C.3.6 Respectively spread the test group specimens and the blank control
