Cable conduits need to work under various environmental conditions, therefore environmental adaptability testing is required to evaluate their performance. The test includes performance evaluation under different temperature, humidity, lighting and other conditions to ensure that the catheter can work stably in various environments. During the production process, cable conduits need to undergo multiple sampling tests to ensure their quality meets the standards. The sampling quantity, sampling method, and inspection standards all need to comply with relevant specifications and requirements.

The size and specifications of cable conduits must comply with design requirements and relevant standards. The test includes the diameter, length, wall thickness, bending radius, etc. of the catheter. Use a bending tester or bending block for testing to simulate the bending of cable conduits in actual use. Bend the conduit within the specified bending radius and observe whether there are any cracks, indentations, or other deformations on its surface, in order to determine whether its flatness meets the standard requirements. For cable conduit joints, sealing tests are required to ensure they do not leak. The testing methods include hydrostatic testing and pneumatic testing, which observe the sealing performance of the joint by applying a certain amount of pressure.
