Electrophysiology catheter
1 Scope
This Standard specifies the terms and definitions, requirements, test methods
for electrophysiology catheter and connection cable.
This Standard is applicable to the electrophysiology catheter specified in 3.1
(hereinafter referred to as the catheter) and connection cable (hereinafter
referred to as the cable). For electrophysiological catheters with special
functions and features, the manufacturer shall supplement the corresponding

4.4 Chemical properties
4.4.1 Reducing substance
The test solution is compared with the same volume and the same batch of
blank control solution. The difference between the consumption of potassium
permanganate solution [c(KMnO4)=0.002 mol/L] shall not exceed 2.0 mL.
4.4.2 Heavy metal
The color of the test solution shall not exceed the standard control solution with
a mass concentration of ρ(Pb2+)=1 μg/mL.
4.4.3 pH
The pH of the test solution is compared with the same batch of blank control
solution, and the difference between pH shall not exceed 1.5.
4.4.4 Evaporation residue
In 50mL test solution, the total mass of non-volatiles shall not exceed 2 mg.
4.4.5 Ethylene oxide residue (if applicable)
The residual amount of ethylene oxide shall be no more than 10 μg/g.
4.4.6 Ultraviolet absorbance
When the test solution has a wavelength range of 250 nm to 320 nm, the
absorbance shall be no more than 0.1.
4.4.7 Corrosion resistance
After the corrosion test, the metal parts of the catheter shall not have corrosion
4.5 Biological performance
4.5.1 Sterile
Sterilized catheter shall be sterile.
4.5.2 Pyrogen
The catheter shall be pyrogen free.
4.5.3 Cytotoxicity
The chemical performance test liquid can be prepared by using only the
material in the catheter that is in contact with the human body to prepare the
test solution. Adopt the method of No. 2 in Table 1 of GB/T 14233.1-2008. If the
finished catheter product is used for verification, the test solution shall be
prepared by using the method without destroying the catheter, and immersed
according to the method of No. 2 in Table 1 of GB/T 14233.1-2008.

requirements of 4.4.1.
5.4.2 Heavy metal
When testing according to 5.6.2 of GB/T 14233.1-2008, it shall meet the
requirements of 4.4.2.
5.4.3 pH
When testing according to 5.4.1 of GB/T 14233.1-2008, it shall meet the
requirements of 4.4.3.
5.4.4 Evaporation residue
When testing according to 5.5 of GB/T 14233.1-2008, it shall meet the
requirements of 4.4.4.
