PA-DOP-01748, R1 Helium Leak Testing Page 4 of 24 1.0 INTRODUCTION Purpose The purposes of this procedure are to describe the process of performing helium leak testing, to provide forms for recording test results, and to define leak test acceptance criteria. The final leak test shall demonstrate the leak tightness of the finished system.
Leak testing with helium or another test gas does not necessarily have to be carried out with the parameters that are decisive for the specification. Conversions are possible, for example, for various gases, gases and fluids, different pressure conditions, mass leak rates and volume leak rates, etc.
MS-40GT Portable Helium Leak Detector. The MS-40GT available either wet or dry pumping package is fully automatic, easy to use, and highly accurate. These advanced leak detectors are ideal for a broad range of applications including clean, oil-free testing. Model No. MS-40GT, Part No. 0137-910-00.
GasCheck G Handheld Helium Leak Detector. The GasCheck handheld helium leak detector represents the latest in gas detection technology. Its advanced system of micro thermal conductivity enables advanced sensitivity for the rapid, effective detection of gas leaks down to ccsec, mgm or ppm levels.
Helium leak detectors also work on principles based from sector field mass spectrometers. Entry gases such as Helium will be analyzed then ionized in vacuum and its ions will be accelerated with the help of added voltage before being separated in a magnetic field. Using a special detector, the helium ion will be turned into an electric current.
Phoenix Quadro Helium Leak Detector. The Phoenix Quadro is a compact helium leak detector with roughing pump Leybold D2.5E inside the unit. The Phoenix Quadro is a portable unit good for leak checking vacuum systems, use at power plants for leak checking condensers and other general applications where precise leak detection is needed.

Clients may request helium leak testing to assess the performance of a material or to analyze or evaluate component longevity. Helium is the preferred leak testing medium because technicians can detect and measure it at minute leak rates less than 1 cubic centimeter300 years and because the gas is inert, meaning it will not react with most components being tested.
Helium is safe because it is non-combustible. A helium molecule has a small diameter and a small mass as well. It is easy to leak through even tiny holes. Usually, helium is present only in small amounts in the atmosphere or metal. Such helium and leaked helium are easy to distinguish. Helium is difficult to be liquefied in a normal environment.

The basic principle of operation of a pressure decay leak test instrument is to fill the test part to a specified target test pressure, isolate the test part from the source air and allow the pressure to stabilize, and then measure the pressure loss due to a leak over a
Helium Leak Detection System . Application. In helium leak testing, a test part is pressurized with a heliumair mixture in a test chamber.The test chamber is then evacuated so that helium is allowed to pass through any leakage points in the surrounding vacuum.
Helium Leak Testing methods can be implemented in simple, manually-operated bench-top systems or in highly automated high volume production systems. This flexible method can be used with or without a test fixture or chamber, for testing in-leakage or out-leakage , and both global leak testing as well as leak location. Select a leak test ...
Vacuum helium leak test systems are used for testing parts with low leak rates and provide better repeatability than other tracer gas leak detection methods. We manufacture standard and custom hard vacuum test systems with extreme sensitivity and fast cycle times. Contact us to learn more.
Helium Leak Testing is a type of non-destructive quality control testing of manufactured parts to ensure fluids do not leak into or out of the part. Depending on the material of the part and the criticality of the application of the part, leak rates to the extent of 1 10-12mbar.l.sec -1 need
LACO manufactures a wide range of Helium Leak Standards using our proprietary micro tube capillary design. We are so confident in the reliability of this design we offer a limited lifetime warranty. These leak standards are available in both reservoir and open-style configurations. For leak rates in the 10-9 range and lower, select a permeation style helium leak standard with reservoir.
There are 2 basic techniques high vacuum testing which allows leak test thresholds to be set down as low as 1 10 -12 mbar.l.sec -1, or sniffing which is generally used for helium leaks down to 1 10 -6 mbar.l.sec -1. For reference 1 cubic millimetre per second is approximately 1 10 -3 mbar.l.sec -1. or 1cc is approximately 1mbar litre per ...
