—How to Choose a Tensile Tester?
1. The universal tensile testing machine should be selected according to the standard adopted and the region where it is sold.
Because different regions adopt different standards. Usually, European customers widely accept the ISO standard system, American customers widely recognize the AATCC and ASTM standard system, while Japanese customers are more inclined to the JIS standard system. Generally, tensile tester manufacturers will indicate in the product manual which standards apply, certainly, you can consult the manufacturer.
2. Consider the tension range of the test material (maximum tensile strength).
The difference in the tension range of the test material will determine the size of the sensor, and the structure of the tensile strength testing machine, but of course, this has little effect on the price (except for the double column type). For general tensile textile testing, a maximum tension of 200N is sufficient. Therefore, the purchase of a single-column tension machine can be. TESTEX universal tensile machine maximum tension of 2500N, a broader range of applications; if the maximum tension needs to exceed 5000N should choose a double-column type.
3. According to the test needs to choose the appropriate maximum stroke.
Usually, the maximum stroke is the distance between the upper and lower fixture (test stroke) + the height of the upper fixture + the height of the lower fixture + the height of the sensor. Because different test materials will need different fixtures, choose a good fixture to know the specific test stroke. In general textile testing, the stroke in 600-800mm can be. Material elongation of more than 1000% can be selected stroke 1000 or 1200mm.
A tensile tester, also named a universal material testing machine, is a kind of tester used for adding the mechanical force to fabrics under the test of their mechanical properties such as instrumentation static load, tensile, compression, bending, shear, tear and peel. It is also suitable for testing various physical and mechanical properties of plastic plates, tubes, profiles, plastic film and rubber, wire and cable, steel, glass fiber, and other materials, becoming an indispensable testing machine for boosting material development, teaching research, quality control, and other aspects. The fixture is a crucial componence of the tester. And different materials call for different fixtures, which plays an important role in finishing the test smoothly and the accuracy of the test result.
The tensile tester is mainly applicable to determine the tensile strength of metal and non-metal materials subject to compression, bending, shear, peeling, tearing, etc, such as rubber, plastic, wire and cable, safety belt, insurance belt, plastic profiles, waterproof coil, copper and so forth.
Measure the displacement by the imported photoelectric encoder. The controller adopts an embedded single-chip microcomputer structure. There is powerful measurement and control software inside the machine which integrates the function of measurement, control, calculation, and storage into one system. It can also carry out the automatic calculation of stress, elongation (need to be equipped with an extensometer), tensile strength and elastic modulus, and even statistics of results. Moreover, it has the function of recording the maximum force, fracture point, force, and elongation at the specified point. It is also characterized by the dynamic display of the test process and test curve by the computer which is used for the data processing. Once the test is completed without any error, you can re-analyze and re-edit the data by enlarging the curve in accordance with the graphic processing module. Finally, you can print the report which will denote that the performance of the product has met the international advanced level.
The tensile tester is extensively used across a wide range of industries, such as measurement and quality inspection, rubber and plastic, metallurgy and steel, machinery manufacturing, electronic appliances, automobile production, textile and chemical fiber, and commercial arbitration, and technical supervision departments, petrochemical and so on.
一 When adding load on the tensile testing machine, the pointer chattering keeps or stops operation from time to time. There are three reasons for this situation.
There is wear in the clutch gear which needs to repair or replace.
There is wear in the leather washer of the friction disk or spring, which needs to replace with another leather washer or spring.
The displacement of the manipulation handle needs to adjust the manipulation handle to match well with the tooth groove.
二 When tensile testing machine pendulum comes back to the original position too fast or slow. There are also three reasons for this situation.
1 the buffer valve block is not properly placed: adjust the buffer valve to the appropriate position.
2 hydraulic oil viscosity is too low or too high: should replace the hydraulic oil with the appropriate viscosity.
3 there is smudginess in the buffer valve, oil pipe, or hydraulic oil: clean the buffer valve and oil pipe. should replace the hydraulic oil.
1 Regularly check the screws in the jaw area. If they become loose, you should tighten them in time.
2 The sliding surface of the steel plate contacting with the liner and the dovetail groove surface on the liner should be kept clean and regularly coated with a thin layer of MoS2 (molybdenum disulfide) grease.
3 Regularly check the transmission of the sprocket. If they become loose, please re-tension the tension pulley.
4 If there is no need to use the machine for a long time, please close the controller and computer.
5 According to the use of the machine and the service life of the oil, regularly replace the oil suction filter and filter element, the hydraulic oil, and regularly check whether there are oil leaks at the host and oil source. If there is any oil leak found, the sealing ring or combination gasket should be replaced in time.
One end of the sample to be tested is held by the upper gripper, and the other end is applied with the standard prescribed pre-tension. It is clamped by the lower gripper. The lower gripper stretches the sample at a constant rate during the test, and the lower gripper drops at a displacement that is the elongation of the sample. The tensile force on the sample is converted into an electrical signal by the sensor connected with the upper gripper, which is amplified by the amplifier and converted by the A/D converter, and the force on the sample during the stretching process is calculated by the microcontroller, and the corresponding data chart is output for reference.
Test procedures (taking the textile tensile test as an example)
(1) Preparation of specimens. According to the fabric species, choose the shape of the test strip, cut the specimen according to the specified specimen size, and the length direction should be parallel to the warp (longitudinal row) or transverse (or horizontal column) of the fabric. Each sample of warp and weft direction specimens at least 5 pieces, and in the standard atmospheric conditions to adjust the wet 4h.
(2) Prepare a tensile testing machine. According to the shape of the fabric with the appropriate clamping fixture.
(3) according to the requirements, adjust the upper and lower clamp spacing (clamping length), and stretching speed.
(4) Clamp the specimen. First, clamp one end of the specimen in the center of the upper clamp, and then put the other end of the specimen into the center of the lower clamp and straighten it under pre-tension; then tighten the lower clamp (or use the loose clamping method).
(5) Start the button to begin repeated testing and output the data information chart.
The rate at which a test is performed can have a significant effect on tensile properties. Materials such as plastics, polymers, steels exhibit tensile properties that are very sensitive to testing rates. Consequently, these types of materials have higher tensile strengths and lower elongation values at faster speeds.
Standardized test methods developed for these materials often specify a loading rate or a range within certain limits. In order to obtain accurate and repeatable results, it is critical to maintain the same loading rate when testing these materials.
We recommend keeping up with the recommended calibration schedules to ensure load and strain measuring devices provide accurate and repeatable results.
2. How does specimen alignment affect tensile properties?
When a specimen is properly aligned, the top and bottom test fixtures are in one straight line with the direction of force, the loading train, and with one another. In addition, the specimen is clamped between the top and bottom grip jaws at the same center line.
