An object with a vacuum (low pressure) inside has less mass than the same object with air (e.g. at ambient pressure of 1bar) inside. That means, if you make a hole into an evacuated object air will flow into it, it will get heavier and "move down." We hope that this answers your question, if not please expand the question in more detail so that we can help you.
The method refers to standard ASTM E493/E493M-11(2022). If you have any further questions please feel free to contact us here: bit.ly/3doW6QZ Your INFICON Social Media Team
