introduction
Breathable packaging materials for medical device sterilization are often provided to medical institutions and medical device manufacturers. Due to two situations such as extinction
The differences in bacterial methods, transport conditions, storage conditions, and shelf life have different requirements for their microbial barrier properties.
This part of YY/T 0681 is technically equivalent to DIN58953-6.2010. Health and safety review of disinfection products issued by the health department
The price regulation stipulates that the package of sterilized articles with a sterilization mark shall be subjected to a microbial barrier test, and the "Disinfection Technical Specifications" gives corresponding
Test method. The test method specified in this standard is consistent with the principle of the method given in the Disinfection Technical Specification (2002 edition).
Medical device manufacturers are required to comprehensively evaluate the microbial barrier properties of breathable packaging materials in accordance with the requirements of GB/T 19633.1.
The test conditions given in this part of YY/T 0681 are relatively low and easy to promote. However, medical device manufacturers are evaluating one
When using the YY/T 0681 part of the MN/T 0681 for the microbial barrier properties of the venting material, the following aspects must be carefully considered.
--- The repeatability and reproducibility results of the test methods given are not very satisfactory (see Appendix A);
--- The acceptance criteria given are still somewhat controversial in the industry.

3 wet conditions microbial barrier test
3.1 Method summary
The microbial droplets were dropped onto the test sample. After the droplets are dried, a test is performed to determine if microorganisms penetrate into the test sample.
the other side.
3.2 Sampling
Sampling according to GB/T 450-2008.
3.3 Sample preparation and quantity
A square having a side length of about 50 mm was cut from the packaging material to be tested for testing. Should be tested according to the manufacturer or customer instructions
The sample is sterilized.
The sample was conditioned for at least 24 h in an environment with a temperature of (23 ± 1) ° C and a relative atmospheric humidity of (50 ± 2)%.
Note. Wet packaging materials can produce false results.
It is advisable to use 5 test samples for each batch of packaging materials, see 3.7.
3.4 medium
3.4.1 General
The medium was prepared using freshly prepared distilled water. Do not use deionized water. Can also be used if there is no newly prepared distilled water
Water for Injection.
