What is the principle of vacuum leak test?
The principle of a vacuum leak test involves detecting and measuring leaks in a sealed system by creating a vacuum inside it and monitoring pressure changes. During the test, the system or container is evacuated to a specified vacuum level. If there is a leak, air or gas will infiltrate, causing a rise in pressure. This change indicates the presence and potential location of a leak.
