  • Application Note: Air Leak Testing for Liquid Leak Sites
    This Application Note discusses two different volumetric flow rate equations and their limitations. The note also cites a recent study done by a car radiator manufacturer that reaffirmed the 4 cc/min test criteria.
  • Detecting Air Leaks in Low Emissivity Enclosures
    the required precise control. When leaks of substantial size occur, thermography provides the solution. A procedure has been developed by the author that will determine the locations of air leaks in a test cell made of metallic materials that are not painted and have a low emissivity value. A modern
  • Pressure Sensors for Leak Detection
    measurement decreases, then air is leaking out of the test part. Measuring the change in pressure over a period of time allows the user to calculate the leak rate.
  • Structural Leak Testing Utilizing a Spray Rack and Infrared Thermography (.pdf)
    This paper will explain the basic procedures utilized in setting up leak testing of window and wall systems. It will cover building and testing the spray rack to ASTM standards, setting up the negative air chamber and performing the testing utilizing digital and infrared thermography.
  • Application Note: The Advantages of Broadband Ultrasonic Analysis During Leak Detection on Compressed Air Systems
    Ultrasonic testing devices have long been established in the field of preventive maintenance to detect leaks on compressed air systems. These devices usually record a frequency range around 40 kHz. SONOTEC Ultraschallsensorik Halle GmbH is breaking new ground with the SONAPHONE ultrasonic testing
  • CASE STUDY: Leak Testing Vacuum Packaged Coffee Pouches
    The customer's product consisted of ground coffee vacuum packed and sealed into small foil packages. Because of this packaging process, there was no "head space" (air or gas space inside the package) to facilitate vacuum decay testing, so a pressure decay chamber test was designed.
  • Pressure Monitoring of Air Leakage Detection Equipment
    Air leakage detector is a commonly used device for detecting various gas leaks and product airtightness. Traditional testing equipment is low in precision, poor in efficiency, and greatly influenced by human factors. Moreover, products such as electrical components cannot quantitatively measure
  • Nondestructive Testing of Nonferrous Tubes, In Particular Copper Tubes
    Tubes made of nonferrous metals are manufactured for an extremely wide variety of applications and must consequently meet the applicable requirements. Proof must be furnished that the requirements are met. Some of these requirements relate to testing for leaks and freedom from surface damage
  • Low Global Warming Potential Refrigerants A New Option for Environmental Test Chambers That Helps Combat Climate Change
    Low Global Warming Potential Refrigerants. A New Option for Environmental Test Chambers. That Helps Combat Climate Change. Weiss Technik North America, Inc. White Paper. 2022. Low Global Warming Potential Refrigerants. White Paper. 2. Table of Contents. Summary
  • Technical Article: Air Under Water (AUW) - Also known as the
    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
  • Technical Article: Traditional Mass Flow Meters
    Typically traditional mass flow sensors are hot wire sensors that operate on the heat loss principle and designed for general flow applications (e.g continuous pipe flow). ATC's micro-flow sensors, like the IGLS, are used for leak testing. They are designed for leak testing, where air flows
  • Flammable Gas Sensors: Which is the Best?
    Flammable gas sensors monitor ambient air for flammable gases like propane, methane, butane, isopropanol, hydrogen or any of over a dozen gases that can easily ignite in air. Even though you don't see them, flammable gas sensors are everywhere. They are used to check for gas leaks in home gas
