The following points need to be paid attention to when using a waterproof and breathable membrane real water tester:
Preparation before the test: Ensure that the test equipment is in normal working condition, and pretreat the waterproof and breathable membrane, such as removing surface dust, oil and other impurities to ensure the accuracy of the test results
Sample Preparation: Cut the material sample into a circle or square of appropriate size to ensure the flatness and consistency of the sample surface and avoid damage or contamination on the sample.
Test Instrument Settings: Adjust the parameters of the test instrument, such as test temperature, humidity and test time, etc., to meet the test requirements.
Sample Loading : Place the sample in the test chamber of the test instrument and ensure that it is well sealed to avoid interference from the external environment on the test results
Test Conduct: Start the test instrument and measure the water vapor transmission rate of the sample over a period of time according to the set parameters, while paying attention to controlling the ambient temperature and humidity during the test to maintain the accuracy of the test.
Recording and analysis of test results: After the test is completed, the test results are recorded and related data analysis is carried out to evaluate the water vapor transmission rate performance of the material sample.
Specific testing process: For example, when testing the airtightness of an audio vent, strict parameter settings need to be followed, including the air intake phase, the voltage stabilization phase and the test phase, as well as the final deflation phase. When the leakage value in the test stage does not exceed 80 Pa, the audio waterproof and breathable membrane is judged to be a qualified product.
Through the above steps and treatments, the accuracy and effectiveness of the waterproof and breathable membrane real water tester can be ensured.
