What is Vacuum Decay Leak Testing Vacuum decay testing is a highly sensitive, non-destructive testing method capable of detecting leaks as small as a few micrometers. It is primarily used to assess the integrity of sealed systems and is suitable for rigid, semi-rigid, and flexible packaging. Unlike traditional testing methods, this approach relies on precision sensors that provide quantitative, reliable, and objective data. This facilitates comparisons between different batches and data traceability, while also supporting compliance verification. Working Principle The test sample is placed inside a test chamber, which is evacuated. Pressure sensors monitor changes in pressure; if the pressure rises, it indicates a leak. Key Benefits of Vacuum Decay Leak Testing

• Non-destructive testing • High sensitivity and accuracy • Detects minute leaks • Compliant with USP <1207> standards • Pharmaceutical blister packs • Sterile medical device packaging • Flexible pouches and bags • Sealed trays and thermoformed packaging • High-barrier food packaging Vacuum decay testing quantifies leak rates, providing a more objective and reliable testing method. It is becoming an essential component of modern quality control systems, particularly in the pharmaceutical and high-risk product industries.
