Operator influence on testing with electronic tensile testing machines

The accuracy of the test results of the electronic tensile testing machine on the one hand is related to the electronic tensile testing machine itself. On the other hand, it has a lot to do with the quality of the electronic tensile testing machine operator. wooTextile Testing Instruments, Testing Equipment Manufacturer

Judging from the records of after-sales maintenance, the overall quality of electronic tensile testing machine operators is generally not high, and their understanding of material-related testing standards is relative superficial, and they can not fully understand that the expertise and theoretical level related to the operation of the testing machine is relatively low, and they are specially trained by the manufacturer's technical staff mmust before they can start their work. wooTextile Testing Instruments, Testing Equipment Manufacturer

After training, most operators just clamp the sample according to the requirements, and then start the instrument to read out the test data directly. For a single function that only performs a single test material, there's nothing wrong with that, but as soon as the material is changed or the mount is changed, it won't work at that point. wooTextile Testing Instruments, Testing Equipment Manufacturer

Using the example of tensile testing of materials, different materials show different strengths at yield points and stress-strain curves, and the test results are also very different. However, some operators confuse the yield strength of metal material with the yield strength of plastic material due to lack of expertise. However, the physical properties of metal materials and plastic materials are very different: metal materials have an upper Stryield strength and a lower yield strength for yield strength, while plastics only have a yield strength. In addition, the yield strength of metal materials must be less than the ultimate strength, while the yield strength of plastics can be less than or equal to the ultimate strength. Due to the operator's own problems, the parameters of the plastic tensile test are used for the tensile test of metal materials, or the parameters of the tensile test of metal materials are used for the plastic tensile test, resulting in some unreasonable discrepancies between the test results and the actual values ​​error. wooTextile Testing Instruments, Testing Equipment Manufacturer

Therefore, improve the quality of the operator of the electronic tensile testing machine and improve the quality of the material too the respective testing theory and the level of knowledge about the operation of the testing machine are of positive importanceutation for improving the accuracy of the test results of the electronic tensile testing machine. wooTextile Testing Instruments, Testing Equipment Manufacturer
