  • What is a Thermal or Temperature Test?
    to purposely induce failures to determine weak points or latent defects. What is thermal vacuum testing?
  • Application Note: Vacuum Decay Testing Using a Self-Contained Vacuum Generator
    A variety of products must be leak tested by subjecting them to vacuum (negative pressure).
  • 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.
  • Low Outgassing Accelerometers and Cables for Thermal Vacuum and Vibration Test Environments
    impossible to remove the accelerometers. Sensors installed for ground vibration testing may, therefore, remain on the structure even if they are no longer needed for testing purposes. In any application involving a thermal vacuum environment care must be taken to select the. proper accelerometers
  • Cryogenic Vacuum Insulation for Vessels and Piping
    Cryogenic vacuum insulation systems, with proper materials selection and execution, can offer the highest levels of thermal performance. Three areas of consideration are vital to achieve the optimum result: materials, representative test conditions, and engineering approach for the particular
  • What is a pressure/vacuum decay test?
    Pressure decay testing measures the change in pressure between atmospheric pressure and your pressurized test sample. Unlike some other current methods of leak testing, this test method yields quantitative information, hard data points that can be recorded and upon which decisions can be made
  • Assessing Work-Basket Alloys for Vacuum Furnaces
    A commercial heat treating company draws on its experience and test results to determine which high-temperature alloys to use for vacuum furnace baskets.
  • What Is A Virtual Leak And How Does It Affect Your Vacuum System?
    A virtual leak is a trapped volume of gas within a vacuum chamber that cannot be easily pumped out due to restrictions in the path connecting the trapped gas to the main chamber. Virtual leaks reference a leak that cannot be found during any activities or tests performed outside of the vacuum
  • Understanding Insulation Resistance Testing
    A regular program of testing insulation resistance is strongly recommended to prevent electrical shocks, assure safety of personnel and to reduce or eliminate down time. It helps to detect deterioration of insulation in order to schedule repair work such as: vacuum cleaning, steam cleaning, drying
  • Case Study: Non-destructive Vacuum Decay Chamber Test - Blister Packs
    Problem/Goal: The customer was looking for a method to confirm. the leak integrity of medical dispenser blister. packs without destroying the package and/or. contaminating the contents. Read about the solution
  • Climatic Chamber for Eight-Thousander Test
    It looks like you are using an old version of the Microsoft Edge browser. To get the best experience with the Busch website, please update your browser. Outdoor jackets and satellite solar panels need to be able to withstand the most adverse conditions. They are subjected to an endurance test
  • Meeting Feedthrough Challenges on the A-3 Test Stand
    The purpose of this paper is to share the experience and knowledge that engineers at NASA and Douglas Electrical have gained regarding the specification of hermetic seals and feedthroughs used in engine test stand vacuum chamber applications. This paper looks specifically at the experience
  • Test it Right for Thin-Cake Filtration Operations
    , centrifuges, belt filters and others. This article concentrates on the testing of pressure or vacuum operations. In solid-liquid separation systems, a wide variety of parameters influence performance. Evaluation and testing procedures can help plants determine the effectiveness of a particular system
