Introduction to the test principle: each component of the shunt should be able to withstand 19The positive pressure of 613 3 kPa (2 m water column) should have no significant change in its characteristics, i.e., within the range of 10% deviation of its specification. Within 2 hours of this pressure being applied, its characteristics should be within the range described.
The anti-vandalism stress test of hydrocephalus is an important test to assess its ability to withstand stress without vandalism. Here are some of the key steps and takeaways from this test:
1.Test preparation: Before you start testing, make sure you have the appropriate test equipment and tools, including pressure testing machines, sensors, brackets, and fixtures. At the same time, make sure that the hydrocephalus device is installed correctly and securely.
2.Set parameters: According to the product specifications and requirements, set the parameters such as the pressure range, loading rate and number of tests for the test. These parameters should be able to simulate the maximum pressure situation that may be encountered in real-world use.
3. Perform a stress test: Connect the hydrocephalus fluidizer to the pressure tester and apply pressure gradually. Observe how the shunt behaves under pressure, specifically for any signs of deformation, cracks, leaks, or other damage.
4. Data Logging: During the test, record the pressure value applied, the reaction of the shunt, and any observed damage. This data is critical for evaluating the performance of the shunt.
5. Result analysis: According to the test data, analyze the performance of hydrocephalus under different pressures. Determine the maximum pressure it can withstand, and whether there is any damage at that pressure. This will help evaluate the quality and reliability of the shunt.
6. Judging criteria: Generally, if the hydrocephalus fluid apparatus is not damaged or leaked under the specified maximum pressure, it can be considered to have passed the anti-destruction stress test. However, the specific criteria may vary depending on the product type and criteria.
7. Follow-up measures: If the test results are not satisfactory, further examination and improvement of the hydrocephalus apparatus is required. This may include adjustments in material selection, structural design, or manufacturing processes.
