What is the protection value of the universal test machine?

The protection value of the universal test mechanism refers to the maximum force value that the machine can exert without damaging the sample or itself. This protection value is usually determined by factors such as the material, shape, size and test requirements of the test sample. It is a safety measure designed to ensure that the sample or the machine itself will not be damaged during the test. During the test, the machine needs to exert a certain force to evaluate the strength, toughness, elasticity and other physical properties of the sample. If the force is applied too much, it may cause damage to the sample or damage the machine itself. Therefore, in order to ensure the testFor accuracy and the safety of the machine, a protection value needs to be set. When the force exerted reaches this protection value, the machine will automatically stop exerting force, so as to avoid possible damage. The setting of the protection value needs to take into account multiple factors, including the material, size, shape, test conditions, etc. of the sample. Different materials and test conditions may require different protection values. Generally speaking, the size of the protection value should be large enough to ensure that the sample or machine will not be damaged during the test, and should not be too large, otherwise it may affect the accuracy of the test results. In a word, the protection value of the universal test mechanism is a safety protection measure to ensure that the sample or the machine itself will not be damaged during the testing process. When setting the protection value, multiple factors need to be considered to ensure that the size of the protection value is appropriate.
