Abstract
A prevacuum steam sterilization test pack, for testing the efficiency of the vacuum system of a steam sterilizer apparatus to create a vacuum, comprises a bundle of layers and a porous overwrap folded about the bundle to maintain the integrity thereof. The bundle includes a porous test sheet with a steam sensitive indicator ink printed thereon positioned between layers of the bundle to indicate the efficiency of the vacuum system of a sterilizer, a plurality of selectively porous layers within the bundle above and below said test sheet, and at least one pair of non-porous gas-impermeable layers disposed intermediate the test sheet and one of the bundle end surfaces. The pair of non-porous layers is spaced from both the test sheet and the one bundle end surface by at least one of the porous layers, and the non-porous layers are spaced apart by at least one and no more than two of the porous layers. The number, the position and spacing apart of the non-porous layers depend upon a predesignated degree of efficiency.
