WebDye Ingress Methods for Container-Closure Integrity Testing: An Industry Position Paper provides guidelines and best practices for the qualification and/or validation and use of a dye ingress test method within a company’s approach to container-closure integrity (CCI). WebAs shown in figure 2, a dye ingress test has only an about 70% chance to detect a 10 µm leak. Any leaks below 5 µm are more or less non-detectable. It is therefore recommended to apply a deterministic integrity test method whenever leakage measurements are based on phenomena that follow a predictable chain of events. The

WebJul 29, 2024 · The blue dye ingress test is quite a simple test. You put the samples in a vacuum chamber, add a blue dye solution and evacuate the chamber. After air is evacuated, you vent the chamber again and put the samples under atmospheric or even overpressure. Due to the pressure difference, the blue dye will penetrate through leaks in the container. cryptography tutorial javatpoint
