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. Vacuum leak tests are widely used for quality control in industries such as packaging, automotive, and aerospace to ensure product integrity, prevent contamination, and maintain performance standards by confirming the airtightness of components or packaging.
