An article to understand the air tightness tester equipment to determine the standard of good and defective products
This paper introduces the working principle of the air tightness tester and the criteria for judging whether a product is air tight or not. It assesses whether a product is qualified or not by measuring the leakage volume/leakage rate, which are key indicators of a product's sealing performance. The article also discusses how to set the values of leakage volume and leakage rate, and emphasizes the importance of further testing of products close to the thresholds in specific cases.
