  • Effective Leak Testing: Are you testing the part or the seal?

    The two most common types of leak test are pressure decay and mass flow. With pressure decay, the part is filled with a volume of air to a specific pressure, then isolated from the air source. The pressure within the part is then monitored to track decreases that indicate the presence and rate of a leak.

  • 5 Tips for Robotic Leak Testing - May 2019 - AUTO TEST - Best

    Robots are not human beings. In manual sniffer leak testing, it is the operatortask to hold - or guide - the probe at a suitable distance over the surface of the component to be tested: close enough without touching or damaging the surface. What works when stationary can fail when moving. The problem of too large a distance becomes even more acute if the probe is not held statically above a certain point, but must be moved over a larger surface, for example along welds or seals. The lower the limit leakage rate, the lower the possible speed. If the oil tightness of a component is to be ensured, a test against leakage rates in the range of 10-3 mbar∙l/s is required. Selecting the right test gas for the intended use. Forming gas (a non-combustible mixture of 95% nitrogen and 5% hydrogen) and helium are probably the two most common test gases.
