Vacuum Decay Test Methods<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Principle of Vacuum Decay Method<\/h3>\n\n\n\n<p>The vacuum decay leak test method operates on the principle of pressure change detection. When a vacuum is applied to a sealed test chamber, any leaks in the tested package will cause a change in the pressure inside the chamber. By monitoring this pressure change over time, the presence and size of leaks can be determined.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.
