The step-by-step procedure for performing a moisture management test using the MMT (Moisture Management Tester) tester is as follows:
a. Ensure that the test instrument is in good working order and calibrated to the proper test specifications.
b. Prepare the test sample, which may be a fabric or other moisture management product.
2. Sample Preparation:
a. Cut samples to appropriate size, typically 10 cm x 10 cm.
b. As required, test areas may be marked on the sample for more accurate measurements.
3. Set up the test instrument:
a. Turn on the test instrument and make sure it is in the correct test mode.
b. Set the test parameters, such as test time, temperature and relative humidity, as required.
4. Place the sample:
a. Open the sample clamp on the test instrument and place the sample to be tested flat on the clamp.
b. Ensure that the sample is not exposed to external interference such as wind or direct light.
5. Initiate the test:
a. Close the door of the test chamber to ensure stable environmental conditions.
b. Start the test instrument to begin the test.
c. Set the test time and other parameters according to the requirements of the test.
6. Monitor and record data:
a. Monitor instrument readings, including data on relative humidity, temperature, and humidity transfer, at regular intervals during the test.
b. Record readings at each point in time and ensure accurate recording.
7. End the test:
a. When the test time is complete, stop the test instrument and turn off the unit.
b. Reset the instrument readings to the initial state.
8. analyze and interpret data:
a. Based on the test results, analyze and interpret the data to determine the moisture management performance of the sample.
b. Compare test results with appropriate standards or specifications to assess whether the sample's performance meets requirements.
9. report preparation:
a. Prepare test reports based on test results, including experimental objectives, methods, results, and conclusions.
b. Provide explanations of the test results and recommendations in the report to help improve the product's moisture management performance.
The test procedure may vary with different equipment and requirements, so please consult the operation manual of the equipment and follow the relevant test standards and protocols before conducting the test. The above steps provide general guidance and can be used as a reference for the basic process of conducting a moisture management test on an MMT tester.
