high-voltage Leak Detection system

Apr 28, 2012While ASTM has not yet established standards for electronic leak detection, both high- and low-voltage methods have a proven track record. High voltage ELD might be preferable in hot, dry weather, as there's no need to maintain a moist surface during testing. (In wet climates, care must be taken to ensure that all test surfaces are completely dry.)

  • Methods in Measuring CCI – Part II: High Voltage Leak

    HVLD equipment operates by moving a high-voltage probe along the length of a syringe; a defect (as small as 2 microns) usually results in a visible discharge through the fluid in the syringe system, however the position of the defect is always recorded. HVLD can be useful for detecting a defect between the syringe body and plunger.
