ABSTRACT:
An improved test pack for determining the efficiency of a vacuum in an autoclave comprises a porous bundle partially including open cell foam and having a plurality of non-porous gas impermeable layers placed on its surface to leave a portion thereof exposed. A sheet with a steam sensitive indicator ink printed thereon is embedded in the bundle for placement in an autoclave where a vacuum is drawn to evacuate air therefrom through the exposed surface portions of the bundle. Steam is then introduced to replace the evacuated air and react with the indicator ink wherever there is contact. The amount of indicator ink contacted by the steam is a measure of the efficiency of the vacuum.
