Aoying anti deformation ability tooling Aoying anti deformation ability tooling

Anti deformation capability toolingIn the YY 0336-2020 standard, it is specifically used to test the anti deformation ability of disposable sterile vaginal dilators, ensuring their structural stability and safety in clinical use.

The core requirements and design of this fixture are as follows:

U-shaped fixture structure: The fixture adopts a U-shaped fixture, and its inner surface needs to basically match the outer surfaces of the upper and lower blades of the expander to ensure uniform force distribution.

Fixture widthThe width of the contact part of the fixture is (3 ± 0.1) mm to precisely control the action area and avoid edge stress concentration.

Range of loading forceThe testing equipment should be able to apply a loading force of 0N-0.5N with an accuracy controlled within ± 0.1N, simulating the deformation under mild external forces in clinical practice.

Test speedThe loading speed should be stable at (90 ± 10) mm/min to ensure that the testing process meets standard dynamic conditions and reflects real usage scenarios.

measurement methodBefore and after loading, use a universal or specialized measuring tool to measure the straight-line distance between the outer edges of the front ends of the upper and lower blades of the expander, accurate to 0.5mm, and calculate the deformation.

environmental conditionsThe test should be conducted in an environment of 22 ℃± 2 ℃, and the sample should be placed under this condition for more than 4 hours to eliminate the influence of temperature on material properties.

This fixture is used in conjunction with a mechanical testing machine and is a key auxiliary device for quality control in medical device manufacturing enterprises and testing institutions, ensuring that products comply with《YY 0336-2020 "Industry Standard.
