The concept of using paper in medical packaging has been accepted widely. as it provides the essential permeability to allow ingress of the sterilising media whilst preventing the post‐penetration of bacteria. thereby maintaining sterility of the medical device itself.
In Europe this widespread application of paper has demanded the introduction of proper standards for sterilization papers and converted items, such as bags and pouches. In this article these standards are discussed, i.e. British Standards, German DIN 58953, French Pharmacopoeia and Eucomed (European Confederation of Medical Suppliers Association).
Comparisons of these standards, including results of our testing, also are presented t o underline the essential differences between specifications for the same grade of paper. In particular, special note is made in the case of air permeability of papers used for gas sterilization. The most reasonable solution is put forward by Eucomed, in which permeability performance is more fully addressed. The principles of various methods for the determination of microbial barrier performances of sterilization papers also are described and some comments in this respect are given.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
