Educational Leak Testing Resources

ATEQ’s Leak Testing Academy is committed to providing educational industrial leak testing information through training courses, white papers, articles, videos and application studies.

White Papers

  • Setting Leak Testing Specifications
    • This article will help provide a guideline on how to determine leak testing specifications. It will provide testing specification examples, theoretical models, and address various considerations such as the consequences of a failed part, test scenarios, test conditions, component material, shelf life, surface tension, hole geometry, air flow models and other leak testing methods.
  • Sealed Component Testing
    • This article is designed to assist people that have never used an air leak tester to quality control test a fully sealed component.  This includes guidance on different test methods, formulas, test fixture designs, test time, test materials, part temperature and test environments that are involved in ingress leak testing products that do not have any openings to connect to a tester such as: food packaging, waterproof electronics, watches, cosmetics, and medical devices
  • Internal Combustion Engine Leak Test
    • This article is designed to assist people that test an automotive engine for smaller leaks in industrial quality control. Proper understanding of engine technology, thermodynamics and pressure regulation can help manufacturers to have better quality control on their fully assembled engines. The simple use of multiple fill points, compressed air tanks, and heat exchangers are key factors in improving the performance of a leak test station.
  • Transmission Leak Test
    • This article is designed to assist people that leak test automotive transmissions for industrial quality control. While most automotive leak testing applications are usually best handled by a differential pressure air leak test, for a transmission leak test, ATEQ actually recommends a flow meter for testing internal and external leaks throughout the cavities of a transmission.
