Abstract
A disposable test package for testing the proper functioning of a steam sterilizer is formed with a test sheet adapted to change color in response to the presence of steam under preselected sterilization conditions. The sheet is surrounded by disposable nonwoven porous material, above and below, forming a core region around the test sheet having desired height and porosity parameters and a shell region around the core having different height and porosity parameters which are adapted to permit the test pack to simulate a Bowie and Dick challenge pack for the testing of steam sterilizers.
