Does the test result of the tensile testing machine have anything to do with the operator?
The entire process of the tensile testing machine test is carried out under human operation and control, and human factors will inevitably affect the test results. Even if a person with careful and serious experimental experience does the experiment, the data will not be completely consistent every time. Human factors involve sampling, sample preparation process, sample processing, test process, data processing, etc. For comparison experiments, it is best to operate with the same person to ensure that the correct conclusions are drawn. Through the above analysis, it is clarified from the perspective of tensile testing machine that there are many factors that affect the results of plastic tensile testing. In addition to internal factors, there are also test environment, test equipment, sample preparation and processing, operation process, data processing, and personnel operation. And other external factors. Some of these external factors are objective aspects, such as temperature and humidity, and some are subjective aspects, such as human operation. These factors will ultimately affect the test results. The tensile test of the same plastic may yield different test and test results. The external factors related to the accuracy of the test data must be fully considered and strictly controlled, especially the subjective external factors, so that the test data has Comparability, consistency and accuracy. Therefore, test personnel must have a high sense of responsibility, strictly implement test standards and operating procedures, and pay attention to maintenance, operation and self-calibration of equipment such as tensile testing machines to ensure that they are in good condition during the experiment to obtain accurate test data. .
