In this article, I made the statement that vulcanized patches were not acceptable because they are impenetrable to steam. This has been called to my attention as an error.
Quite a few years ago, I tested the patching material and found it to be a barrier to steam. I have, therefore, tested it again and found that my assumption is now incorrect. The patching material is permeable to both steam and ethylene oxide.
The tests were carried out very simply. A piece of wide patching material was folded back on tests and the sides were sealed by heat treatment to form a pocket. Into this pocket spore strips and an integrator were placed. The end was then sealed. A small piece of wood
