How to do airtightness and waterproof test for medical devices, using this one method is enough
This paper describes the importance and methods of waterproof testing of medical devices for airtightness. It focuses on the pressure drop method of pressure testing (gas testing), which determines leakage by observing the pressure change after increasing the pressure, emphasizes its advantage of simplicity and speed, and compares the high cost of other testing methods such as vacuum testing (helium testing).
