Generally , the test environment of the electronic tensile testing machine determines the accuracy of the test data, the integrity of the test equipment, etc., so in order to obtain accurate test data, the environmental requirements related to the electronic tensile testing machine should be strictly observed. Generally speaking, it can be divided into six categories. This is just a general introduction. When using the electronic tensile testing machine, users must follow the relevant standards of the corresponding materials.
1. The laboratory space must be larger than the size of the electronic tensile testing machine itself, such as the vertical electronic tensile testing machine model, such as the 3 m ring stiffness testing machine. For the convenience of testing and placement, the laboratory space should at least It is 4 meters; for horizontal electronic tensile testing machines, the space of the laboratory is up to several tens of meters because of its unique test space requirements.
2. The humidity of the thermometer in the laboratory must be controlled within a certain range. If the test temperature is too high, it is easy to increase the frequency of failure of the motor and sensor of the test equipment. If the indoor humidity is too high, the equipment will be produced. Rust, in short, if there are no special requirements, all materials are required to be in the range of room temperature 10 ° C -35 ° C, and the relative humidity is not more than 80%.
3. The ground at the position where the electronic tensile testing machine is installed must be flat and stable. If it is not flat, the electronic tensile testing machine will inevitably produce a certain inclination, so the upper and lower clamps of the clamp cannot maintain the coaxiality. The test results have a great impact.
4. The power supply voltage in the laboratory should be stable and cannot fluctuate too much back and forth. It is similar to household appliances. The voltage fluctuation is too large, and the electrical switch back and forth will cause the electrical appliance to malfunction. Equipment that is typically fluctuating like an electronic tensile tester should not exceed ±10% of the voltage.
5. Corrosive media around the electronic tensile testing machine is absolutely impossible. After all, the testing equipment is metal products. Once the electronic tensile testing machine is damaged, it will reduce the mechanical properties such as strength, plasticity and toughness of the metal material.
6. The laboratory where the electronic tensile testing machine is located should not have vibration. If the vibration is generated during the test, it will affect the test data, and if it is in this case for a long time, it will cause the sensitivity of the sensor, encoder, etc. .
