This Part of EN 868 provides test methods and values for materials for preformed sterile barrier systems and packaging systems that are intended to maintain sterility of terminally sterilized medical devices to the point of use. This Part of EN 868 introduces no additional requirements to the general requirements specified in EN ISO 11607-1. As such, the particular requirements in 4.2 can be used to demonstrate compliance with one or more but not all of the requirements of EN ISO 11607-1. NOTE 1 If the intended use as specified by the manufacturer includes the possibility of the material being used as a sterile field or a surgical drape the EN 13795 series applies. NOTE 2 If the intended use as specified by the manufacturer includes the possibility of the material being used as container filter or as an inner wrap for containers then additional and/or other requirements can apply, see e. g. EN 868-8.
