What is the standard for an air permeability tester?

 

This standard applies to the air permeability test of paper, cardboard, plastic film, fabric and other materials. It specifies the requirements for test instruments, test methods, test sample size and test conditions. These include test conditions such as atmospheric pressure, temperature and relative humidity.

This standard applies to the air permeability test of textiles. It specifies the requirements for test instruments, test methods, test sample size and test conditions. These include test conditions such as atmospheric pressure, temperature and relative humidity.

 

This standard applies to the air permeability test of medical masks. It specifies the requirements for test instruments, test methods, test sample size and test conditions. These include test conditions such as test time, test flow and test pressure.
 

When using the Air Permeability Tester for testing, it is necessary to select the corresponding standard test method according to different materials and application fields to ensure the accuracy and repeatability of the test results. At the same time, attention should be paid to complying with the test conditions and operating requirements stipulated in the test standards, such as applying standard pressure, adjusting test time or flow, etc. In addition, it is also necessary to pay attention to the influence of the test environment, such as wind force, water vapor, temperature and humidity, etc., so as to avoid the interference of external factors on the test results.

 

In a word, the standard of Air Permeability Tester is a very important reference in material air permeability test, it can help testers to choose appropriate test methods and test conditions to ensure the accuracy and repeatability of test results, so as to meet the requirements of different application fields Require.
