The sensitivity of the test depends heavily on the test parameters, specifically the vacuum level. The standard suggests that with optimal conditions, the method can detect holes as small as a specific micron diameter (often cited around 50 to 125 microns depending on the specific apparatus and product headspace). astm d3078

However, ASTM D3078 is designed for detecting . It is not intended to detect ultra-fine leaks that might require trace gas detection (like Helium leak testing) or high-voltage leak detection. The standard suggests that with optimal conditions, the
