Internal Pressure

The hazardous material package test specifications require that any sealed vessel be subjected to a pressure differential test equal to one atmosphere. The test is designed to guarantee that packages subject to high temperatures and/or lower external pressures (higher altitude) will not leak or explode.

This test can be conducted by means of internal pressurization of the package system or by means of drawing a vacuum in the area immediately surrounding the sealed container. The internal pressurization method is often favored because of its ability to determine the margin of safety built into a given package design.
