  • Technical Article: Air Under Water (AUW) - Also known as the "Bubble Test" / Dye Penetrant Leak Test
    AUW, also referred to as the "bubble test," may be okay for medium and large leaks, but is poor for SPC and correlation to other leak test methods is almost impossible. AUW can be used to detect. Air Under Water (AUB) - Bubble Test and Immersion Leak Testing. Please Note: You are viewing
  • High Throughput Leak Detection
    Various methods have historically been used to check leaks in systems and components from bubble tests to rotameters and pressure loss detection. While these traditional methods have their place, they each have serious drawbacks in accuracy, throughput, and automation. High Throughput Leak

    of the test equipment available. The limited dynamic range of conventional helium leak detectors required that a secondary test procedure be developed to cover the large, or gross, leak range. Several methods have been tried, and the most commonly used procedure, referred to as the bubble test, involves

  • Medical Device Link .
    struggle with the possibility of false-positive results when performing sterile integrity testing (bubble-leak or dye-penetration tests) on a flexible sterile barrier system (SBS) containing porous materials. A false positive can occur when a flexible pouch containing a porous material is bent, folded

    of pinholes, stress cracks, or other breaks in coating integrity. For microelectrodes, it may be possible to use a bubble test, in which the electrodes are immersed in a saline solution and subjected to a current; any subsequent hydrogen evolution indicates a break in a coil insulation.8 In all

    of helium transferred through the part indicating a leak. So why are the valves used in testing important? If the valves being used to control the test are themselves leaking,. then yo u cannot tell if the product under test is leaking.  The Dale Advantage.  Bubble Tight – The patented poppet design
