ABSTRACT:
Disclosed is an apparatus and method for testing the integrity and acceptability of the seal of a package before or after it has been sterilized by any chosen conventional process which may include heat sterilization of a sealed package, aseptic packaging or irradiation. Testing is accomplished by subjecting the package or container to a controlled external pressure, preferably a linear actuator, sufficient to create a selected level of internal pressure. Any suitable means may be used to determine the rate of pressure change within a selected time interval. Upper and lower limits of pressure change determine whether the seal is acceptable.
