Patent ID: 6935163

Claim:
A method for leak testing of a part comprising: A. presetting of a plurality of test parameters including: (1) test pressure value; (2) standard pressure differential value; (3) total test time; (4) snapshot time delay; (5) slam test time; (6) slam pressure differential value; B. sealing of the test part with a fill line and a pressure sensing means attached thereto in fluid flow communication with respect to the sealed environment therewithin; C. pressurizing of the test part by supplying fluid through the fill line into the part being tested while monitoring thereof; D. ceasing pressurization of the test part; E. pausing for a period of time of a duration equal to the snapshot time delay; F. determining the snapshot pressure value by measuring the instantaneous current pressure within the pressurized part; G. calculating the low good standard threshold pressure by subtracting the standard differential value from the snapshot pressure value; H. calculating the low good slam threshold pressure by subtracting the slam differential value from the snapshot pressure value; I. measuring of the current pressure instantaneously within the part being tested; J. delay for a period of time equal to the slam test time after determining the snapshot pressure value; K. performing slam test by determining whether the measured current pressure is greater than the low good slam threshold pressure value, and, if yes, then proceeding to display the good part indicator and proceeding to depressurizing; L. performing standard test by determining whether the measured current pressure is less than the low good standard threshold pressure, and, if yes, displaying bad part indicator and proceeding to depressurizing; M. further performing of the standard test repeatedly until expiration of the total test time and then, if all standard tests result in a no result, proceeding to display a good part indicator and depressurizing; and N. depressurizing the test part.
