ABSTRACT:
A method and apparatus for testing containers for pressure leak characteristics is disclosed. The arrangement includes monitoring the fluid pressure in a container supplied with test fluid at two different time intervals, with the monitored difference being compared with a predetermined acceptable value of container pressure loss and a signal generated to either accept or reject the tested container. To facilitate a continuous updating of the calibration of the acceptable pressure loss, a digital computer controlled arrangement is provided for adjusting the predetermined acceptable pressure loss value as a function of the monitored difference in the pressures for containers previously tested.
