Modern airtightness testing technology is evolving rapidly, with inspection times ranging from seconds to minutes. Optimizing test times can save costs and increase efficiency. Choosing the right equipment, optimizing the process, training personnel and using data analysis are key. Case studies show that optimizing test time can lead to significant cost reductions.
This article describes four common methods for testing the waterproofness of product seals: pressure testing, vacuum testing, watertightness testing and spray testing. Each method has its own principle, test method, advantages and disadvantages. The choice of test method should be based on the actual product, and combined with a variety of tests to ensure that the airtightness waterproof performance in line with the standard.
This article details the seven common testing principles and methods used in airtightness testers, including positive pressure, negative pressure, quantitative, flow, differential pressure, positive and negative pressure and helium mass spectrometry, as well as factors to consider when selecting an airtightness tester, such as testing accuracy, speed, range and reliability. The article emphasizes the importance of choosing the right airtightness testing instrument for different application needs and budgets.
This article describes in detail the classification of airtightness tester, test methods and their applications in industrial production. The article classifies the airtightness tester according to the airtightness detection principle, detection object, automation degree, application environment and product function, and introduces the three test methods of bubble method, pressure drop method and mass spectrometry and their advantages and disadvantages.
This paper describes the importance and methods of waterproof testing of medical devices for airtightness. It focuses on the pressure drop method of pressure testing (gas testing), which determines leakage by observing the pressure change after increasing the pressure, emphasizes its advantage of simplicity and speed, and compares the high cost of other testing methods such as vacuum testing (helium testing).
