Geotextile tensile test testing equipment generally includes accessories such as tensile testing machines, fixtures, and steel rulers. The following are general test methods for geotextile tensile tests:
1. Prepare the test sample: According to the test standards and requirements, cut out the geotextile test sample that meets the requirements, and record its size and weight.
2. Install the test sample: place the test sample in the fixture of the testing machine, make sure that the sample is clamped evenly without slipping or twisting.
3. Set test parameters: Set test parameters according to test standards and requirements, such as loading speed, loading method, test temperature, etc.
4. Start the test: start the tester and start the test. The testing machine automatically applies force, stretching the sample until it breaks. The testing machine records the force and elongation data during the test.
5. Analysis of test results: According to the test results, calculate the tensile strength, elongation, elongation at break and other parameters of the sample, and perform data analysis and statistics.
It should be noted that when conducting tensile tests on geotextiles, relevant testing standards and specifications should be followed, such as GB/T 1040.1-2006, GB/T 1040.2-2006, etc. At the same time, in order to ensure the accuracy of the test results, the following items should be noted:
1. The selection and preparation of samples should meet the test standards and requirements.
2. The installation of fixtures and testing machines should meet the testing standards and requirements to ensure that the test samples are clamped evenly without slipping or twisting.
3. The setting of test parameters should meet the test standards and requirements, such as loading speed, loading method, test temperature, etc.
4. During the testing process, attention should be paid to the stability and accuracy of the testing machine to avoid failures or errors.
5. After the test is completed, the test samples and test instruments need to be cleaned and maintained to ensure the long-term stable operation of the test instruments.
To sum up, the tensile test of geotextile needs to use special tensile testing machine and accessories, and follow the relevant testing standards and specifications for testing.
