ABSTRACT:
An improved test fixture for verifying the reliability of leak detectors in a can-making line, comprising a can body having an orifice of a predetermined size formed therein and piece of filter paper of predetermined porosity, attached to the interior of the container by a double-faced tape, overlying the orifice. A fluid, maintained at a predetermined pressure, is introduced into the body to produce a simulated leak having a predetermined flow rate. Identification of the test fixture as a "leaker" proves the reliability of the leak detector.
A method is also provided for producing the test fixture.
