When choosing the environment and experimental equipment, we must follow some basic principles to select, so as to have safety and quality assurance. What are the basic principles?

First, the reproduction of environmental conditions, first of all, do not hold the natural environment that you want to completely present the outside world in the laboratory. In the current science, this is impossible. However, if there is a certain amount of error, you can still do it.
Secondly, the repeatability of environmental conditions. If it is an environmental test equipment, it is of course impossible to use it only once, it can be tested multiple times. In order to ensure the comparability of the test results of the same product under the environmental test conditions specified in the same test specification, the environmental conditions provided by the environmental test equipment must be reproducible.
Thirdly, the testability of environmental condition parameters, as long as the environmental test equipment must have the conditions, not only can limit the environmental parameters within a certain tolerance range, but also ensure the reproducibility and repeatability of the experimental conditions . And it is also necessary from the safety of product testing in order to prevent damage to the tested product due to uncontrolled environmental conditions and bring unnecessary losses.
Fourth, the exclusiveness of the environmental test conditions, because each time the test has strict regulations on the type, quality and tolerance of environmental factors, it is necessary to exclude the influence of the non-experimental environment Yisu, so that it is convenient in the test After the fire test, the failure mode of the product is determined and analyzed to provide a strong basis. Therefore, in addition to providing the specified environmental conditions, the environmental test equipment is not allowed to add other environmental stress interference to the tested product.
Fifth, the safety and reliability of the test equipment, the period of the environmental test is relatively long, and the object of the test is sometimes a high-value military product. During the entire experiment, the test personnel often have to operate around the site or It is testing work. Therefore, for safety reasons, the test equipment must have the characteristics of safe operation, convenient operation, reliable use, and long working life to ensure the normal conduct of the test itself.
