PURPOSE: To provide a biological sterilized test pack such that testing conditions can be changed without changing an assembly consisting of first to fifth sets by providing a sheet of unperforated paper covering the overall outer periphery of the assembly and having porosity as a cover material, for the purpose of controlling the flow of steam and air going into and out of the assembly. CONSTITUTION: A sheet serving as a cover material made of unperforated paper whose porosity can be checked although being low, e.g. an overlap sheet 60, is provided to cover the overall outer periphery of an assembly 62 comprising first to fifth sets 14, 20, 30, 40, 50. The overlap sheet 60 controls the flow of steam and air going into and out of the assembly 62. The level of a porosity requirement given by the test pack can be attained by changing the degree of porosity of the overlap sheet 60 without changing the assembly 62. It can also be attained by holding time degree of porosity constant, covering the assembly 62 so that the number of layers of the overlap sheet 60 or the number of some of the layers vary, and changing the size of the overlap sheet 60. |
